You can iterate over the dialogs children and check which ones are check boxes like this: wxWindowList children = dialog->GetChildren(); for ( auto it = children.begin() ; it != children.end() ; ++ it ) { wxCheckBox* c = wxDynamicCast(*it,wxCheckBox); if ( c ) { // Do something with with the check b...

There doesn't seem to be a MSW only InitFromHBRUSH method like there is with some of the other GDI objects. But what you can do is call GetObject to get a LOGBRUSH. Then use the information in that structure to create a wxBrush.

Here's a discussion of ARM support for macOS from the wxDev group.

Basically the plan is to build universal binaries containing both ARM and x86-64 code similar to how the situation was handled during the transition from powerpc to x86.

Just use raw pointers. The panel is owned by the frame and so it will be deleted when the frame is destroyed. So there is no possibility of leaking the panel object.

Setting colors for native controls is usually not a good idea. It may not work or may not work as intended. Even if it works on one port, it may not work on other ports. As the documentation states : Notice that as with SetForegroundColour(), setting the background colour of a native control may not...

This tells all windows to resize to the minimum size. Just use SetSizer instead.

As the documentation states : When writing a multi-threaded application, it is strongly recommended that no secondary threads call GUI functions. What you can do is throw an event from your secondary thread and then in the handler for that event call Update/Refresh on the panel. The page for wxThrea...

Good morning, what IDE, Designer or program are you using in these images?

Those images are from wxFormBuilder.

I'm not sure what, but there is some setting that makes the tab key not work on linux. You can see it in the stc sample: the tab key does not work in the main frame but it does work with the mini editor frame. Also the tab key works if you create a plain stc without any configuration at all. I would...

This was discussed in the comments here and should have been fixed by this PR.

If there is still and issue, you should probably mention it in the comments for the second PR or open and issue on trac.

I wrote about this here.

Matching positions for is not easy. An example of how to do this is given by the SurfaceImpl::MeasureWidths method defined in src/stc/PlatWX.cpp from the wxWidgets source. I assume you have a function for styling line in wxString form. ie you already have this function void StylewxString(const wxStr...

You should be able to use wxMemoryOutputStream. I haven't tested this, but this should work: if (wxFileName::FileExists(source_file)) { wxFileInputStream input(source_file); wxMemoryOutputStream memOut(NULL); input.Read(memOut); wxStreamBuffer* buffer = memOut.GetOutputStreamBuffer(); const auto fil...

There are a number of "raw" methods supplied with wxStyledTextCtrl that allow you to get information from the control without converting from/to wxString. I think in particular GetLineRaw would be helpful here.

The proportion option is under "sizer item" near the bottom of the grid:

Note that the setting will be ignored unless "stretch" is selected for the item on the toolbar:
