My understanding is that FilterEvent does not prevent the iconize from happening, it just prevents it from sending an event to the window.

Can you just omit the wxMINIMIZE_BOX flag from the window style for your frame to prevent the user from attempting to iconize the window?

C++ Precompiled Headers in VS2002

Hey. I'm completely new to the whole precompiled header thing. Up until now I haven't been using them, and have just been enduring the compile times. Now I'm interested in trying out precompiled headers to see if they can cut down on compile time. I checked the wiki and available documentation, and ...

Thanks for the reply! Good to know I can create it on the stack. I was worried about ownership issues but it's great that I don't have to worry about that. I did a bit more research after my first post and it looks like wxCommand::Command() does pretty much exactly what I want. wxCommandEvent kind o...

Send sel change events from wxListBox derived

I derived a class from wxListBox which has the ability to remove items from the list via a call to Delete(). The thing is, Delete() does not send any selection changing events to the parent window.. and I would like this to happen. So my question is how do I manually notify the parent window of a se...

RTTI, dynamic casting, wxClientData questions

I'm trying to tie some data to entries in a list box. I'm doing this by deriving a class (called SourceInfo) from wxClientData, and supplying it to my call to Append() when adding items to the list box. I had problems downcasting from wxClientData* to SourceInfo*. I ran through the RTTI section in t...

I'm having problems logging onto to the tracker -- logging in keeps taking me to the registration page. Blech.

Whatever -- too much hassle for something not that important. If anyone else wants to bring this to the developers' attention, I'd be grateful, but I'm not going to bother.

Thanks.

Hiding top level windows before destroying

This isn't so much of a question as much as a way to avoid a weird visual quirk when destroying top level windows (like frames, dialogs). I suppose it's also a feature request for future versions of wx. I honestly didn't know which forum to post this in -- this one seemed like the most appropriate. ...

I know this is solved and you're using vectors now, but I felt I should mention this anyway: Since you were using new[] for all items, you should use delete[] for all, too. vsp's code suggestion had the right idea, but he made a somewhat critical mistake: for(int i=0; i<cagestotal; i++) { delete[] c...

You're trying to draw one window (canvas_OpenGL) from another window's (Window) Paint event. This isn't the right way to approach this. You want to draw to canvas_OpenGL in canvas_OpenGL's paint event -- not in Window's paint event. This means you should do the following: 1) derive a class from wxGL...

I also I see you create wxPaintDC(this). It seemd like you,re catching the paint even of the window, and drawing on the window. Instead, catch the paint event of the GL cavas and draw on the GL canvas. See the wiki for a full example. Ah you're right. Looks like he's trying to paint to window A fro...

Re: wxStaticBox as a parent

Whoops. I totally missed that blurb in the docs about how you shouldn't use wxStaticBox as a parent for controls. I'd assume this also means you shouldn't use it as a parent for GL canvases on those platforms... right? With that in mind I tried the next thing I could think of, which was to put a sec...

wxStaticBox as a parent

I recently was having troubles with a wxGLCanvas in a panel on my dialog. I've gotten this to work on dialogs before with the exact same code, so I was baffled. After a bit of tinkering I realized the problem was that I was trying to put my GLCanvas inside a wxStaticBoxSizer with the panel as the pa...

Ah!

Such an obvious solution and yet I didn't think of it. Putting each chunk in a panel will actually be much easier.

Thanks!

Yuk... so I have to manually traverse each element in the sizer -- and then recursively step through any included sizers? What exactly is the point of DeleteWindows then?
