wxPython and STC Margins - Top and Bottom

wxPython and STC Margins - Top and Bottom - python

Is there any way of implementing padding in the top and bottom of my program for 3 and 4?
Or is there a workaround like adding \n etc....
I feel asif the line numbers and the Styled text are too close to the top and bottom.

How about using panels of the same color nested inside the sizer as a dirty workaround?
import wx
import wx.stc as stc
class MainWindow(wx.Frame):
def __init__(self, *args, **kwargs):
wx.Frame.__init__(self, *args, **kwargs)
self.panel = wx.Panel(self)
self.text = stc.StyledTextCtrl(self.panel)
self.text.SetWindowStyle(self.text.GetWindowStyle() | wx.NO_BORDER)
self.text.StyleSetSpec(stc.STC_STYLE_DEFAULT, "size:15,face:Courier New")
self.text.SetWrapMode(stc.STC_WRAP_WORD)
self.text.SetMarginLeft(50)
self.text.StyleSetSpec(stc.STC_STYLE_LINENUMBER, "back:#FFFFFF")
self.menu = wx.Menu()
self.menu.Append(wx.ID_ABOUT, "&About", "Information about this program")
self.menu_bar = wx.MenuBar()
self.menu_bar.Append(self.menu, "&File")
self.SetMenuBar(self.menu_bar)
self.panel_top = wx.Panel(self.panel, size = (20, -1))
self.panel_top.SetBackgroundColour(wx.WHITE)
self.panel_bottom = wx.Panel(self.panel, size = (20, -1))
self.panel_bottom.SetBackgroundColour(wx.WHITE)
self.sizer = wx.BoxSizer(wx.VERTICAL)
self.sizer.Add(self.panel_top, 0, wx.ALL | wx.EXPAND)
self.sizer.Add(self.text, 1, wx.ALL | wx.EXPAND)
self.sizer.Add(self.panel_bottom, 0, wx.ALL | wx.EXPAND)
self.border = wx.BoxSizer()
self.border.Add(self.sizer, 1, wx.ALL | wx.EXPAND, border=20)
self.panel.SetSizerAndFit(self.border)
self.text.Bind(stc.EVT_STC_CHANGE, self.OnChange)
self.Show()
self.text.SetText("Line!\n"*3)
def OnChange(self, e):
lines = self.text.GetLineCount()
width = self.text.TextWidth(stc.STC_STYLE_LINENUMBER, str(lines)+" ")
self.text.SetMarginWidth(0, width)
if __name__ == "__main__":
app = wx.App(False)
win = MainWindow(None)
app.MainLoop()
For your code, modify it as follows:
self.panel_top = wx.Panel(self.panel, size = (20, -1))
self.panel_top.SetBackgroundColour(wx.BLACK)
self.panel_bottom = wx.Panel(self.panel, size = (20, -1))
self.panel_bottom.SetBackgroundColour(wx.BLACK)
#### Add the STC to a Sizer. ####
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(self.panel_top, 0, wx.EXPAND,border=20)
sizer.Add(self.text, 1, wx.EXPAND,border=20)
sizer.Add(self.panel_bottom, 0, wx.EXPAND,border=20)
self.panel.SetSizer(sizer)

No, I don't think that Scintilla has a property that controls the size of the top and bottom margins.

wxPython - How to hide and show items in a centred BoxSizer without moving everything else?

I have a button to copy text from a TextCtrl and I want to display a message next to it to confirm that the text has been copied to the clipboard. So I'm using a StaticText that hides and shows when the button is clicked.
I have put the button and the StaticText in a horizontal centred BoxSizer. The thing is when the StaticText shows, as the BoxSizer's children are centred it moves them. Here is my code:
def __init__(self, *args, **kw) -> None:
super(Window, self).__init__(*args, **kw)
# create a panel in the frame
pnl = wx.Panel(self)
# create some widgets in the panel
self.text_area1 = wx.TextCtrl(pnl, style=wx.TE_MULTILINE | wx.TE_NOHIDESEL)
self.text_area2 = wx.TextCtrl(pnl, style = wx.TE_MULTILINE | wx.TE_READONLY | wx.TE_NOHIDESEL | wx.TE_RICH2)
btn_correct = wx.Button(pnl, label="Correct >>>")
btn_correct.Bind(wx.EVT_BUTTON, self.on_press_correct)
self.btn_copy = wx.Button(pnl, label="Copy")
self.btn_copy.Bind(wx.EVT_BUTTON, self.on_press_copy)
self.label = wx.StaticText(pnl, label="Text copied")
self.label.Hide()
self.timer = wx.Timer(self)
self.Bind(wx.EVT_TIMER, self.on_timer, self.timer)
# create a sizer to manage the layout of child widgets
sizer = wx.BoxSizer(wx.VERTICAL)
sub_sizer = wx.BoxSizer(wx.HORIZONTAL)
sizer.Add(self.text_area1, 1, wx.ALL | wx.EXPAND, 5)
sizer.Add(btn_correct, 0, wx.ALL | wx.CENTER, 5)
sizer.Add(self.text_area2, 1, wx.ALL | wx.EXPAND, 5)
sub_sizer.Add(self.btn_copy, 0, wx.ALL | wx.CENTER, 5)
sub_sizer.Add(self.label, 0, wx.ALL | wx.CENTER, 5)
sizer.Add(self.sub_sizer, 0, wx.BOTTOM | wx.CENTER, 5)
pnl.SetSizer(sizer)
def on_press_copy(self, event):
data_obj = wx.TextDataObject()
data_obj.SetText(self.text_area2.GetValue())
if wx.TheClipboard.Open():
wx.TheClipboard.SetData(data_obj)
wx.TheClipboard.Close()
self.btn_copy.Disable()
self.label.Show()
self.label.GetParent().GetSizer().Layout()
self.timer.StartOnce(3000)
else:
wx.MessageBox("Can't open clipboard", "Error")
def on_timer(self, event):
self.btn_copy.Enable()
self.label.Show(show=False)
self.label.GetParent().GetSizer().Layout()
How can I achieve that without moving the button when the StaticText shows?

I have added a dummy element (filler - size >= length of label text) and used that to the left of the button and created a sizer (label_sizer which contains the filler element) to the right. That means the button does not move when the text is shown

For reference, a partial code snippet, with errors, won't help get your question attention.
Obviously, centring 1 item versus 2 items, is never going to work. There will always be a difference.
You'll need to find another way.
You could output a messagebox or update the status line or use a different sizer, which probably gives you an approximation, of what you're after.
e.g.
Here I use a GridBagSizer and simply update the label text.

It isn't perfect but it's close.

I thought for stuff like that the status bar was first choice

pass information among panels in wxpython

I have a pretty complicated wxpython app that has nested notebooks and panels. Basically the structure is that in my main frame I have a notebook (let's say notebook 1, in one page of the notebook I have two panels (upper and lower). In the lower panel I have another notebook (lets say notebook 2). So the question is how do I pass information between these two notebooks pages, and to the upper panels.
I know that there are basically three ways of passing information: by event id, by publisher, by .parent and .child. However I am really confused with the difference of these three methods and when to use them.
I have attached my code as below.

As you can see, I have a search condition panel and a result panel that are used in different pages. For each specific page, the search condition and result could be different and only for that page. So my question is, what is the best way to pass the search condition (i.e. data and file name) to the corresponding page to display the result (i.e. the "getResult" function inside "ResultTablePanel" doesn't work).
For example, inside the "order page", the search condition panel has user input start and end dates, and the file name. Below the search condition panel is the result panel showing the computed result based on the search condition. Once the "Start" button is clicked, the "start date", "end date" and "file name" variables are passed to the result panel ("ResultTablePanel") within the "order page". Similarly, since the "Mode page" also calls both "ResultTablePanel" and "SearchConditionPanel", it should have its own "start date", "end date" and "file name" variables (note that they can be same or different from the ones inside "order page"), and its own result displayed in "ResultTablePanel".
Thank you in advance for taking time reviewing and answering my question.

Thank you everyone again! Much appreciated.

I usually recommend using Pubsub for this sort of thing. It's very easy to implement and makes it easy to pass a message to one or more recipients (panels).
Here's a simple example:
import wx
from wx.lib.pubsub import pub
class OtherFrame(wx.Frame):
""""""
def __init__(self):
"""Constructor"""
wx.Frame.__init__(self, None, wx.ID_ANY, "Secondary Frame")
panel = wx.Panel(self)
msg = "Enter a Message to send to the main frame"
instructions = wx.StaticText(panel, label=msg)
self.msgTxt = wx.TextCtrl(panel, value="")
closeBtn = wx.Button(panel, label="Send and Close")
closeBtn.Bind(wx.EVT_BUTTON, self.onSendAndClose)
sizer = wx.BoxSizer(wx.VERTICAL)
flags = wx.ALL|wx.CENTER
sizer.Add(instructions, 0, flags, 5)
sizer.Add(self.msgTxt, 0, flags, 5)
sizer.Add(closeBtn, 0, flags, 5)
panel.SetSizer(sizer)
def onSendAndClose(self, event):
"""
Send a message and close frame
"""
msg = self.msgTxt.GetValue()
pub.sendMessage("panelListener", message=msg)
pub.sendMessage("panelListener", message="test2", arg2="2nd argument!")
self.Close()
class MyPanel(wx.Panel):
""""""
def __init__(self, parent):
"""Constructor"""
wx.Panel.__init__(self, parent)
pub.subscribe(self.myListener, "panelListener")
btn = wx.Button(self, label="Open Frame")
btn.Bind(wx.EVT_BUTTON, self.onOpenFrame)
def myListener(self, message, arg2=None):
"""
Listener function
"""
print "Received the following message: " + message
if arg2:
print "Received another arguments: " + str(arg2)
def onOpenFrame(self, event):
"""

"""
frame = OtherFrame()
frame.Show()
class MyFrame(wx.Frame):
""""""
def __init__(self):
"""Constructor"""
wx.Frame.__init__(self, None, title="PubSub Tutorial")
panel = MyPanel(self)

And here is some additional information:
https://wxpython.org/Phoenix/docs/html/wx.lib.pubsub.html
https://www.blog.pythonlibrary.org/2013/09/05/wxpython-2-9-and-the-newer-pubsub-api-a-simple-tutorial/

You mention three ways of passing information but I have to confess I don't understand what you are talking about (and I've written many wxWidget applications). One way of handling the situation you describe is for the event handler to call a function in the parent class, which can then relay the information to other functions/classes. Schematically:
class A:
def __init__(self):
B(self)
self.c = C(self)
def a_function(self, *data):
# do something with the data
# you can pass the information to class C here
class B:
def __init__(self, parent):
self.parent = parent
def an_event_handler(self):
data = something
self.parent.a_function(data)
# or use wx.CallAfter for later execution
class C:
pass
Another solution is the MVC concept, where your event handler passes its information to a model class which stores it or processes it further. This model class can raise a custom wx Event, which components of the UI can then handle as necessary to redraw any affected widgets.

Get Position of Button in wxpython

I am trying to figure out the position of two buttons in wxpython. I have a gui with a small vertical panel on the left and large panel on the right.
wx.Frame.__init__(self, *args, **kwds)
self.Splitter = wx.SplitterWindow(self, -1)#, style=wx.SP_NOSASH)
self.Panel1 = wx.Panel(self.Splitter, -1)
self.Panel3 = wx.Panel(self.Splitter, -1)
self.Splitter.SplitVertically(self.Panel1,self.Panel3,350)
In in the right panel (a notebook) I use a Vertical Sizer to stack three panels:
self.Notebook3 = wx.Notebook(self.Panel3, -1)
self.OptPane = scrolled.ScrolledPanel(self.Notebook3, -1)
self.pane1 = wx.Panel(self.OptPane,-1, style=wx.NO_BORDER)
self.pane2 = wx.Panel(self.OptPane,-1, style=wx.RAISED_BORDER)
self.pane3= wx.Panel(self.OptPane,-1, style=wx.NO_BORDER)
My pane 3 contains three buttons that are organized using a gridsizer (one row, three columns). It all looks great. Now, I want to be able to get the screen position of the three buttons (they change based on resolution of screen, person adjusting the size of the gui, etc.).
My screen size is (1920,1080) which is derived from wx.GetDisplaySize(). I have tried self.button1.GetScreenPosition() and self.pane3.GetScreenPosition and self.button1.GetPosition(). The first returns the position (77,93), second returns (61,95) and the last one gives me (0,0). After testing with testtext = wx.StaticText(self.Notebook3, -1, 'X marks spot',pos=(240,820)), I figured out the position of the button I want returned is (240,820) -- approximately. This is the number I want to return.
Does anyone know what I am doing wrong? Thanks!
*EDIT*
My Full Code - should be runnable -- I am running this on a 1920x1080 (for the text 'x marks the spot').

I think you're asking for the position too soon. You'll want to get the position after everything is rendered to the screen, so you'll probably need to use wxPython's CallAfter. Create a method that looks something like this:
def printLocation(self):
""""""
print self.Button1.GetScreenPosition()
Then at the end of your init, add the following line:
wx.CallAfter(self.printLocation)
When I ran it on my system, I got (155, 211), which is probably closer to what you're looking for. I have a rather weird resolution here.
You might also want to look at this thread which talks about the scrolled window's CalcUnscrolledPosition method.

Why does my horizontal sizers change width after adding them to a vertical sizer?

When I only hade one TxtCtrl, it's right side would expand all the way to the windows edge. But after I created a vertical BoxSizer to and added the horizontal one to that, the TxtCtrol only had a width of about 100 pixels. Why is this?
import wx
class MainPanel(wx.Panel):
def __init__(self, parent):

box2.Add(wx.StaticText(self, 1, "Path: "), 0, wx.LEFT|wx.RIGHT|wx.TOP, 5)
box2.Add(texturePath, 1, wx.ALIGN_LEFT|wx.RIGHT|wx.TOP, 5)

self.panel = MainPanel(self)
self.Show()
if __name__ == "__main__":
app = wx.PySimpleApp()
frame = MainFrame(None, -1)
frame.Centre()
app.MainLoop()
pass

You need to use wx.EXPAND in the style.
top_box.Add(box1, 0, wx.EXPAND)
top_box.Add(box2)
From here: "When an item is Add'ed with the wxEXPAND flag, the item will be resized to fill its alloted area in the opposite orientation."

wxpython layout with sizers

I'm having difficulty getting my sizers to work properly in wxpython. I am trying to do a simple one horizontal bar at top (with text in it) and two vertical boxes below (with gridsizers * the left one should only be 2 columns!! * inside each). I want the everything in the image to stretch and fit my panel as well (with the ability to add padding to sides and top/bottom).
I have two main issues:
1. I cant get the text in the horizontal bar to be in the middle (it goes to the left)
2. I would like to space the two vertical boxes to span AND fit the page appropriately (also would like the grids to span better too).
Here is my code (with some parts omitted):
self.LeagueInfoU = wx.Panel(self.LeagueInfo,-1, style=wx.BORDER_NONE)
self.LeagueInfoL = wx.Panel(self.LeagueInfo,-1, style=wx.BORDER_NONE)
self.LeagueInfoR = wx.Panel(self.LeagueInfo,-1, style=wx.BORDER_NONE)
vbox = wx.BoxSizer(wx.VERTICAL)
hbox1 = wx.BoxSizer(wx.HORIZONTAL)
hbox2 = wx.BoxSizer(wx.HORIZONTAL)

Is this what you're after?
import wx
class Frame(wx.Frame):
def __init__(self, parent):
wx.Frame.__init__(self, parent)
self.panel = wx.Panel(self)
main_sizer = wx.BoxSizer(wx.VERTICAL)
# Title
self.centred_text = wx.StaticText(self.panel, label="Title")
main_sizer.Add(self.centred_text, 0, wx.ALIGN_CENTRE | wx.ALL, 3)
# Grids
content_sizer = wx.BoxSizer(wx.HORIZONTAL)
grid_1 = wx.GridSizer(12, 2, 0, 0)
grid_1.AddMany(wx.StaticText(self.panel, label=str(i)) for i in xrange(24))
content_sizer.Add(grid_1, 1, wx.EXPAND | wx.ALL, 3)
grid_2 = wx.GridSizer(10, 3, 0, 0)
grid_2.AddMany(wx.StaticText(self.panel, label=str(i)) for i in xrange(30))
content_sizer.Add(grid_2, 1, wx.EXPAND | wx.ALL, 3)
main_sizer.Add(content_sizer, 1, wx.EXPAND)
self.panel.SetSizer(main_sizer)
self.Show()
if __name__ == "__main__":
app = wx.App(False)
Frame(None)
app.MainLoop()

something like this??
import wx
class MyFrame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self,None,-1,"Test Stretching!!")
p1 = wx.Panel(self,-1,size=(500,100))
p1.SetMinSize((500,100))
p1.SetBackgroundColour(wx.GREEN)
hsz = wx.BoxSizer(wx.HORIZONTAL)
p2 = wx.Panel(self,-1,size=(200,400))
p2.SetMinSize((200,400))
p2.SetBackgroundColour(wx.RED)
p3 = wx.Panel(self,-1,size=(300,400))
p3.SetMinSize((300,400))
p3.SetBackgroundColour(wx.BLUE)
hsz.Add(p2,1,wx.EXPAND)
hsz.Add(p3,1,wx.EXPAND)
sz = wx.BoxSizer(wx.VERTICAL)
sz.Add(p1,0,wx.EXPAND)
sz.Add(hsz,1,wx.EXPAND)
self.SetSizer(sz)
self.Layout()
self.Fit()
a = wx.App(redirect=False)
f = MyFrame()
f.Show()
a.MainLoop()

Here's one way to do it:
import wx

class MyPanel(wx.Panel):
""""""
#----------------------------------------------------------------------
def __init__(self, parent):
"""Constructor"""
wx.Panel.__init__(self, parent)
mainSizer = wx.BoxSizer(wx.VERTICAL)
hSizer = wx.BoxSizer(wx.HORIZONTAL)
leftGridSizer = wx.GridSizer(rows=10, cols=12, vgap=5, hgap=5)
rightGridSizer = wx.GridSizer(rows=10, cols=3, vgap=5, hgap=5)
title = wx.StaticText(self, label="Main title")
mainSizer.Add(wx.StaticText(self), 0, wx.EXPAND) # add a "spacer"
mainSizer.Add(title, 0, wx.CENTER, wx.ALL, 10)
for row in range(1, 11):
for col in range(1, 13):
lbl = "Row%s Col%s" % (row, col)
leftGridSizer.Add(wx.StaticText(self, label=lbl))
hSizer.Add(leftGridSizer, 0, wx.ALL, 20)
for row in range(1, 11):
for col in range(1, 4):
lbl = "Row%s Col%s" % (row, col)
rightGridSizer.Add(wx.StaticText(self, label=lbl))

mainSizer.Add(hSizer)
self.SetSizer(mainSizer)

To learn about spanning rows, I recommend looking at the wxPython demo. I think that may only be supported in wx.GridBagSizer and the FlexGridSizer though. You can try the span parameter though. Also, it should be noted that wx.GROW and wx.EXPAND are one and the same. You might also want to check out the wiki for more information: http://wiki.wxpython.org/GridBagSizerTutorial

Python is a programming language that lets you work quickly and integrate systems more effectively.

wxPython and STC Margins - Top and Bottom - python

Is there any way of implementing padding in the top and bottom of my program for 3 and 4? Or is there a workaround like adding \n etc.... I feel asif the line numbers and the Styled text are too close to the top and bottom.

No, I don't think that Scintilla has a property that controls the size of the top and bottom margins.
