I've created wx.Grid widget inside my frame and I want to change my type of cursor if the user is using the grid widget. I've managed to do that with wx.StockCursor and .SetCursor methods but my cursor keeps returning to standard cursor if the user moves the cursor above the intersections of cell and row borders. What is causing this?
import wx
import wx.grid as Gridw
class Frame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, wx.ID_ANY, 'Data selection', size=(785, 540))
self.Centre()
#------------------------------------------------------------------------------
panel = wx.Panel(self, wx.ID_ANY)
#------------------------------------------------------------------------------
self.grid = Gridw.Grid(panel)
self.grid.CreateGrid(250, 250)
self.grid.EnableDragGridSize(0)
self.grid.DisableDragColSize()
self.grid.DisableDragRowSize()
self.grid.SetColMinimalWidth(0, 100)
#------------------------------------------------------------------------------
sizer = wx.BoxSizer(wx.HORIZONTAL)
sizer_v = wx.BoxSizer(wx.VERTICAL)
sizer_v.Add(wx.Button(panel, -1, 'Button'), 1, wx.CENTER | wx.ALL, 5)
sizer.Add(self.grid, 1, wx.EXPAND, 5)
sizer.Add(sizer_v, 0)
panel.SetSizer(sizer)
#------------------------------------------------------------------------------
self.CreateStatusBar()
self.Show(True)
#------------------------------------------------------------------------------
cross_c = wx.StockCursor(wx.CURSOR_CROSS)
self.grid.SetCursor(cross_c)
if __name__ == '__main__':
app = wx.App()
frame = Frame().Show()
app.MainLoop()
Looks like the problem is related to that you've disabled grid resizing via EnableDragGridSize(0), DisableDragColSize() and DisableDragRowSize(). This can somewhat explain why you are seeing standard cursor on the cell borders.
Not sure if it'll help you since I don't know what OS are you using, but this works for me on linux:
cross_c = wx.StockCursor(wx.CURSOR_CROSS)
self.grid.GetGridWindow().SetCursor(cross_c)
One more option is to listen for EVT_MOTION and set cursor in the event listener:
self.cross_c = wx.StockCursor(wx.CURSOR_CROSS)
self.grid.GetTargetWindow().SetCursor(self.cross_c)
wx.EVT_MOTION(self.grid.GetGridWindow(), self.OnMouseMotion)
def OnMouseMotion(self, evt):
self.grid.GetTargetWindow().SetCursor(self.cross_c)
evt.Skip()
Hope that helps.

I'm adding elements to a horizontal wx.BoxSizer, but instead of being layed-out next to each other, they are displayed on top of each other (all are placed in pixel position (0,0) of the parent panel).
Below are shortened versions of the files (the relevant parts):
main.py:
import wx
from frm_users import UsersForm
class MainFrame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, wx.ID_ANY, "My App Title", size=(1200, 800))
self.panel = wx.Panel(self, wx.ID_ANY)
self.statusbar = self.CreateStatusBar(2)
self.statusbar.SetStatusWidths([-1, 60])
# this event is bound to a menu item I construct elsewhere
def onUsers(self, event=None):
frmUsers = UsersForm(self.panel)
if __name__ == "__main__":
app = wx.App(False)
frame = MainFrame()
frame.Show()
app.MainLoop()
frm_users.py:
from dbmodel import OlvUsers, Users
import forms_controller
import wx
class UsersForm(wx.Panel):
def __init__(self, parent):
# parent here is the panel
toolbox = forms_controller.getToolboxSizer(self, parent)
parent.SetSizer(toolbox)
def onSearch(self, event=None):
print("Searching")
forms_controller.py:
import wx
def getToolboxSizer(parent, frame):
# frame is a panel usually
toolboxSizer = wx.BoxSizer(wx.HORIZONTAL)
toolboxSizer.AddSpacer(5)
font = wx.Font(10, wx.SWISS, wx.NORMAL, wx.BOLD)
# create the search related widgets
searchByLbl = wx.StaticText(frame, label="Search By:")
searchByLbl.SetFont(font)
toolboxSizer.Add(searchByLbl, 0, wx.ALL, 5)
cat = ["Author", "Title", "ISBN", "Publisher"]
categories = wx.ComboBox(frame, value="Author", choices=cat)
toolboxSizer.Add(categories, 0, wx.ALL, 5)
search = wx.SearchCtrl(frame, style=wx.TE_PROCESS_ENTER)
search.Bind(wx.EVT_TEXT_ENTER, parent.onSearch)
toolboxSizer.Add(search, 0, wx.ALL, 5)
return toolboxSizer
What am I missing?
In main.py, the instance of UsersForm is not inside of a sizer. Panels do not fill their parent automatically except when they are the sole child of a wx.Frame. To make this work, you should add frmUsers to a sizer that is associated with the panel in the frame.
I think there may also be an issue in getToolboxSizer since the widgets there appear to be getting added directly to the frame instead of a panel. You usually want to add child widgets to a Panel so that tabbing will work correctly.
I would probably change onUsers to the following:
def onUsers(self, event=None):
child_sizer = getToolboxSizer(self.panel)
self.main_sizer.Add(child_sizer, 0, wx.ALL, 5)
Then update getToolboxSizer so it doesn't place all its widgets on the parent since the parent will now be a panel.
I'm creating a wx.agw.SuperToolTip. I'm updating the message in the tip every few seconds, and if the tip is showing when the message updates the tip is redrawn in a different position.
The new position seems to be relative to the original position's relation to the top left corner of the screen, but that could just be coincidence.
Also, if I modify wx.lib.agw.supertooltip.ToolTipWindowBase.Invalidate() by commenting out the call to self.CalculateBestSize() the problem goes away. Of course then the window won't resize, so that's no solution.
I'm using wxPython 2.8.12.1.
Here's an app that demonstrates the problem:
class MyFrame(wx.Frame):
def __init__(self, parent, title):
wx.Frame.__init__(self, parent, -1, title,
pos=(150, 150), size=(350, 225))
panel = wx.Panel(self)
btn = wx.Button(panel, -1, "Hover over this")
self._superTip = SuperToolTip("")
self._superTip.SetHeader("Heyo!")
self._superTip.SetTarget(btn)
self._superTip.EnableTip(True)
self._superTip.SetDrawHeaderLine(True)
self._superTip.SetDrawFooterLine(True)
self._superTip.SetStartDelay(1)
self._superTip.SetEndDelay(60)
currentFooterFont = wx.SystemSettings.GetFont(wx.SYS_DEFAULT_GUI_FONT)
currentFooterFont.SetPointSize(6)
currentFooterFont.SetWeight(wx.NORMAL)
self._superTip.SetFooterFont(currentFooterFont)
self._superTip.SetFooter('(Click to close)')
self._superTip.ApplyStyle("Blue Glass")
self._superTip.SetDropShadow(True)
self.ttTimer = wx.Timer(self)
self.ttText = 'What the?'
self.Bind(wx.EVT_TIMER, self.onTimer, self.ttTimer)
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(btn, 0, wx.ALL, 10)
panel.SetSizer(sizer)
self.ttTimer.Start(2000)
panel.Layout()
def onTimer(self, evt):
self._superTip.SetMessage(self.ttText)
self.ttText += '?'
class MyApp(wx.App):
def OnInit(self):
frame = MyFrame(None, "STT error demo")
self.SetTopWindow(frame)
frame.Show(True)
return True
app = MyApp(redirect=True)
app.MainLoop()
Any thoughts on how I can update a visible tooltip without its location changing?
Thanks a lot.
I am writing a text editor using wxpython. I want to display the line & column numbers based on the position of the text pointer(when changed using keyboard or mouse), in the statusbar.
I tried to do it using the below code:
import wx
class TextFrame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, -1, 'Text Editor', size=(300, 250))
self.panel = wx.Panel(self, -1)
self.multiText = wx.TextCtrl(self.panel, -1,"",size=(200, 100), style=wx.TE_MULTILINE|wx.EXPAND)
sizer = wx.BoxSizer()
sizer.Add(self.multiText, proportion=1, flag=wx.CENTER|wx.EXPAND)
self.panel.SetSizer(sizer)
self.CreateStatusBar()
self.multiText.Bind(wx.EVT_KEY_DOWN, self.updateLineCol)
self.multiText.Bind(wx.EVT_LEFT_DOWN, self.updateLineCol)
def updateLineCol(self, event):
#lineNum = len(self.multiText.GetRange( 0, self.multiText.GetInsertionPoint() ).split("\n"))
l,c = self.multiText.PositionToXY(self.multiText.GetInsertionPoint())
self.StatusBar.SetStatusText(str(l)+","+str(c), number=0)
event.Skip()
app = wx.App(False)
frame = TextFrame()
frame.Show()
app.MainLoop()
I tried the below 2 ways to achieve that:
1.) lineNum = len(self.multiText.GetRange( 0, self.multiText.GetInsertionPoint() ).split("\n"))
2.) l,c = self.multiText.PositionToXY(self.multiText.GetInsertionPoint())
But, both, always give the line & column values of previous position of the pointer instead of current.
Is there a way to display the current line & column values?
I think you just need to bind to EVT_KEY_UP instead of EVT_KEY_DOWN. That way the event handler isn't called until after you have finished typing. I also updated the content written to the statusbar to make it a bit clearer which value was which:
import wx
class TextFrame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, -1, 'Text Editor', size=(300, 250))
self.panel = wx.Panel(self, -1)
self.multiText = wx.TextCtrl(self.panel, -1,"",size=(200, 100), style=wx.TE_MULTILINE|wx.EXPAND)
sizer = wx.BoxSizer()
sizer.Add(self.multiText, proportion=1, flag=wx.CENTER|wx.EXPAND)
self.panel.SetSizer(sizer)
self.CreateStatusBar()
self.multiText.Bind(wx.EVT_KEY_UP, self.updateLineCol)
self.multiText.Bind(wx.EVT_LEFT_DOWN, self.updateLineCol)
def updateLineCol(self, event):
#lineNum = len(self.multiText.GetRange( 0, self.multiText.GetInsertionPoint() ).split("\n"))
l,c = self.multiText.PositionToXY(self.multiText.GetInsertionPoint())
stat = "col=%s, row=%s" % (l,c)
self.StatusBar.SetStatusText(stat, number=0)
event.Skip()
app = wx.App(False)
frame = TextFrame()
frame.Show()
app.MainLoop()
I am trying to make a window with 2 panels. One panel is just a notebook panel. The second panel contains a toolbar on top and a text control on the bottom. I want to arrange this panel in my frame using wx.aui.AuiManager.
The problem is that I get a big empty space of grey in my custom panel.
Here is my code:
import wx
import wx.aui
import images # contains toolbar icons
class MyFrame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, wx.ID_ANY,
"AUI Tutorial",
size=(600,400))
self._mgr = wx.aui.AuiManager()
self._mgr.SetManagedWindow(self)
notebook = wx.aui.AuiNotebook(self)
nb_panel = TabPanel(notebook)
my_panel = MyPanel(self)
notebook.AddPage(nb_panel, "First Tab", False)
self._mgr.AddPane(notebook,
wx.aui.AuiPaneInfo().Name("notebook-content").
CenterPane().PaneBorder(False))
self._mgr.AddPane(my_panel,
wx.aui.AuiPaneInfo().Name("txtctrl-content").
CenterPane().PaneBorder(False))
self._mgr.GetPane("notebook-content").Show().Top().Layer(0).Row(0).Position(0)
self._mgr.GetPane("txtctrl-content").Show().Bottom().Layer(1).Row(0).Position(0)
self._mgr.Update()
class MyPanel(wx.Panel):
"""
My panel with a toolbar and richtextctrl
"""
def __init__(self,parent):
wx.Panel.__init__(self,parent=parent,id=wx.ID_ANY)
sizer = wx.BoxSizer(wx.VERTICAL)
toolbar = wx.ToolBar(self,-1)
toolbar.AddLabelTool(wx.ID_EXIT, '', images._rt_smiley.GetBitmap())
self.Bind(wx.EVT_TOOL, self.OnExit, id=wx.ID_EXIT)
toolbar.Realize()
sizer.Add(toolbar,proportion=0,flag=wx.ALL | wx.ALIGN_TOP)
text = ""
txtctrl = wx.TextCtrl(self,-1, text, wx.Point(0, 0), wx.Size(150, 90),
wx.NO_BORDER | wx.TE_MULTILINE | wx.TE_READONLY|wx.HSCROLL)
sizer.Add(txtctrl,proportion=0,flag=wx.EXPAND)
self.SetSizer(sizer)
def OnExit(self,event):
self.Close()
class TabPanel(wx.Panel):
def __init__(self,parent):
wx.Panel.__init__(self,parent=parent,id=wx.ID_ANY)
sizer = wx.BoxSizer(wx.VERTICAL)
txtOne = wx.TextCtrl(self, wx.ID_ANY, "")
txtTwo = wx.TextCtrl(self, wx.ID_ANY, "")
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(txtOne, 0, wx.ALL, 5)
sizer.Add(txtTwo, 0, wx.ALL, 5)
self.SetSizer(sizer)
if __name__ == "__main__":
app = wx.PySimpleApp()
frame = MyFrame()
frame.Show()
app.MainLoop()
So, how do I fix my code so that I don't have that grey block taking up MyPanel? Also, my toolbar button doesn't seem to run self.OnExit(). Why is that?
Thank you for your help.
Take out the line:
self._mgr.GetPane("notebook-content").Show().Top().Layer(0).Row(0).Position(0)
As for the OnExit() handler, it is firing!
If you want to exit the application, replace it with app.Exit()
I'm creating a small wxPython utility for the first time, and I'm stuck on a problem.
I would like to add components to an already created frame. To do this, I am destroying the frame's old panel, and creating a new panel with all new components.
1: Is there a better way of dynamically adding content to a panel?
2: Why, in the following example, do I get a a strange redraw error in which in the panel is drawn only in the top left hand corner, and when resized, the panel is drawn correctly?
(WinXP, Python 2.5, latest wxPython)

1) I beleive the Sizer will let you insert elements into the existing ordering of them. That would probably be a bit faster.
2) I don't see the behavior you're describing on OSX, but at a guess, try calling self.Layout() before self.Show() in layoutElements?
I had a similar problem where the panel would be squished into the upper-right corner. I solved it by calling panel.Fit().
In your example, you should call self.panel.Fit() after self.panel.SetSizer(vbox)
