XRC, wxMenuBar's, and wxMenuBarPtr's

I have an XRC file that contains a complete menubar. I load this
menubar into a frame with:

self.ResMenu = wxXmlResource(" menus.xrc",0)
self.MenuBar = self.ResMenu.Lo adMenuBar("Menu BarEditor")
self.SetMenuBar (self.MenuBar)

Then set up a menu event handler:

EVT_MENU(self, XRCID("MenuItem SnapToGrid"), self.OnSnapToGr id)

Finally, in OnSnapToGrid, I try to get a specific wxMenuItem by using
the wxMenuBar.FindI tem:

m = self.MenuBar.Fi ndItem(XRCID("M enuItemSnapToGr id"))

This falls flat on its face because:

AttributeError: wxMenuBarPtr instance has no attribute 'FindItem'

It seems that LoadMenuBar returns a wxMenuBarPtr rather than a
wxMenuBar. My question then is given a wxMenuBarPtr and the ID of the
menu-item (via XRCID), how do I get ahold of the wxMenuItem object?
Alternativly, is there a way to check/uncheck a wxMenuItem without
having a reference to the actual object (using the id or similar)?

Thanks in advance,

Mark Moss

Hi all, I can't get a py2exe compiled app to run with numarray (numarray-0.5.win32- py2.2). Also wxPythonWIN32-2.3.3.1-Py22 and ActivePython-2.2.1-222. In the sample below, commenting out "import numarray" allows the exe to run. Left in, I get "4.exe has generated errors" etc. I'm going around and around and there isn't much on Google. py2exe output is last.

Hi all, I have a problem for which I wasn't able to find an answer anywhere else, maybe someone can give me a hint... I designed with XRCed a small GUI (the code is at the bottom of the message) made up of a menu and a frame in which there are two panels, placed by an horizontal sizer.

Hi, i'm trying to convert my java console app to a python gui. Now, the only problem i seem to have at the moment are the resizers for the layout. It seems that for the purpose of what i'm trying to do, specifying the coordinates is easier that fighting with the layout resizers. 1) I have a screen split in 2. Left side is a textcontrol where logging will end up. All text will be appended to the textcontrol. Ideally this should allow...

I've started taking a look at wxPython, and, well, I've noticed that the syntax needed to code with it is extremely ugly. I am wondering if there exist any preprocessing tools or clever refactorings that allow users to write more sane-looking code. In particular, it seems to me that the structure of the code often does not reflect the structure of the GUI being designed. For instance, the wxPython wiki "Getting Started" guide includes...

I need some help. I cant seem to get rid of this error. I can program a button that will exit the program and remove the icon in the taskbar, but I have to tie it to OnTaskBarClose. OnExit and OnCloseWindow do nothing and leave the icon in the taskbar, I think I have tried every option, when you double click the icon it gives you the error. Traceback (most recent call last):

I am totally new to Python and WxPython and need to write an application which can open up an external windows from a plug-in within GAIM (using pyGAIM). I have managed to hack some code together from what little I have covered so far, however GAIM refuses to open until I have closed the extra window. I appreciate this is probably a simple point but I would be grateful for any advice people can offer on how I can make them both appear so...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
