I am using wxPython to write an app. I have a menu that pops up. I would like to know how to keep it on the screen after the user clicks an item on the menu. I only want it to go away after the click off it or if I tell it to in the programming. Does anyone know how to do this?
I am using RHEL 6 and wxPython 3.01.1
I don't think the regular wx.PopupMenu will work that way. However if you look at the wxPython demo, you will see a neat widget called wx.PopupWindow that claims it can be used as a menu and it appears to work the way you want. The wx.PopupTransientWindow might also work.
I am developing the GUI for my application using wxpython and have most of the features down, except in the main frame/window I want to have a box for choosing a file (in this case, the input will have to be an excel file). Something similar to the standard filebrowser that is accessed whenever you choose "open" from a menu.
Below is an image to show exactly what I want...
You probably want a wx.FileDialog. It provides access to the default file dialog of the OS your app is running in. You can see an example of how it's used in the wxPython demo package. This tutorial also has some screenshots and sample code:
http://www.blog.pythonlibrary.org/2010/06/26/the-dialogs-of-wxpython-part-1-of-2/
The screenshot you show appears to be an interface to actually open the dialog. You can easily create that using sizers and basic widgets. Then just bind the open button to a handler that will show the dialog.
You might also want to take a look at the FileBrowseButton from wx.lib.filebrowsebutton (also in the demo).
There are a few other related widgets which you might be interested in too: wx.DirDialog, MultiDirDialog or wx.GenericDirDialog.
Assuming you know the basics of wxPython you can use wx.GenericDirCtrl and wx.ListCtrl to make nice browser
I'm just starting out learning python with GEdit plus various plugins as my IDE.
Visual Studio/F# has a feature which permits the highlighting on a piece of text in the code window which then, on a keypress, gets executed in the F# console.
Is there a similar facility/plugin which would enable this sort of behaviour for GEdit/Python? I do have various execution type plugins (Run In Python,Better Python Console) but they don't give me this particular behaviour - or at least I'm not sure how to configure them to give me this. I find it useful because in learning python, I have some test code I want to execute particular individual lines or small segments of code (rather then a complete file) to try and understand what they are doing (and the copy/paste can get a bit tiresome)
... or perhaps there is a better way to do code exploration?
Many thx
Simon
Yes, you use "external tools plugin"
http://live.gnome.org/Gedit/ToolLauncherPlugin
As an example,
Edit > Preferences
Plugins
Tick "External Tools"
Close the Preferences Window
Tools > Manage External Tools
Click the "Add new too" icon in the bottom left
Name it "Execute Highlighted Python Code"
give it a keyboard shortcut
change the input combo box to : "highlighted selection"
change the output to : "Display in Bottom Pane"
In the editor window for the tool, replace everything with :
.
#!/usr/bin/env python
import sys
result = eval(sys.stdin.read())
print expression, "=>", result, type(result)
.
If you wish to see the result of entire .py file, you can put this code in your new created external tool window
#!/usr/bin/env python
import sys
exec(sys.stdin.read())
and change the Input to Current document.
For python, You can use "external tools plugin":
#!/bin/sh
python3 "$GEDIT_CURRENT_DOCUMENT_PATH"
Option of external tool:
Save: Current Document
Input: Current Document
Output: Display in bottom panel
Language: Python or Python3
Don't forget the quotes around $GEDIT_CURRENT_DOCUMENT_PATH....
To answer your second question, and hopefully guide you in a direction you'll be happier with, I think you ought to consider trying some different editors. There are many with more powerful code exploration features than GEdit has. Check out this post:
What IDE to use for Python?
I installed iPython console in gedit and do most of my simple scripting in it, but gedit is a very simple editor, so it'll not have some advance feature like an IDE
But if you want code exploring, or auto completion, I recommend a real IDE like Eclipse.
If you just want a editor, KomodoEdit is fine.
What I do is keep a file called python_temp.py. I have a shortcut to it in my dock. I use it as a scratch pad. Whenever I want to quickly run some code, I copy the code, click the shortcut in the doc, paste in the text and hit f5 to run. Quick, easy, simple, flexible.
I think what you're looking for is http://live.gnome.org/Gedit/Plugins/BetterPythonConsole.
You hit F5 and it runs the code in your file in a IDLE-like console. I don't know if it can only run selected code. (I don't think it can) but you can always copy the needed code in a new window and run it from there.
Have a look through the plugin list for other interesting stuff: http://live.gnome.org/Gedit/Plugins
The closest to a decent IDE...
Install gedit-developer-plugins (through synaptic || apt-get) and don't forget to enable (what you need) from gEdit's plugins (Edit->Preferences [tab] plugins) and happy coding
How can I get a list of the running applications? I'm referring to the ones in the panel at the bottom of the screen.
I believe what you are looking for is libwnck
The panel you are referring to is the GNOME panel. So this is a GNOME question, not a GTK question.
There is not a well-defined concept of "multi-window application" in GNOME that I know of. The panel task list is probably build by querying the window manager for the list of windows and grouping the windows by their "class" property.
There are also various window manager hints that must be taken into account, for example to ignore panels and other utility windows. In your place, I would look at the source code of the taskbar applet. There is maybe some documentation somewhere that covers the status-quo, but I do know where it would be.
I am making a Python gui project that needs to duplicate the look of a Windows gui environment (ie Explorer). I have my own custom icons to draw but they should be selectable by the same methods as usual; click, ctrl-click, drag box etc. Are any of the gui toolkits going to help with this or will I have to implement it all myself. If there aren't any tools to help with this advice would be greatly appreciated.
edit I am not trying to recreate explorer, that would be madness. I simply want to be able to take icons and lay them out in a scrollable window. Any number of them may be selected at once. It would be great if there was something that could select/deselect them in the same (appearing at least) way that Windows does. Then all I would need is a list of all the selected icons.
Python has extensions for accessing the Win32 API, but good luck trying to re-write explorer in that by yourself. Your best bet is to use a toolkit like Qt, but you'll still have to write the vast majority of the application from scratch.
Is there any way you can re-use explorer itself in your project?
Updated for edited question:
GTK+ has an icon grid widget that you could use. See a reference for PyGTK+: gtk.IconView
In wxPython there's a plethora of ready-made list and tree controls (CustomTreeCtrl, TreeListCtrl, and others), a mixture of which you can use to create a simple explorer in minutes. The wxPython demo even has a few relevant examples (see the demo of MVCTree).
I'll assume you're serious and suggest that you check out the many wonderful GUI libraries available for Python.
