You don't need to delete mainWindow. As part of application termination, wxWidgets destroys all top level widows.

The dialogs sample is in the samples folder that comes with the wxWidgets library - specifically in the folder <WXROOT>/samples/dialogs. If you're using a separate worker thread, it's very important that you never call gui methods from the secondary thread. So you'll have to update the progress dial...

It sounds like what you want is the wxProgressDialog class. There is a short example this page and larger example in the dialogs sample.

The usual way to do this is to to create is to create an initially hidden panel, add all the controls to it, and then show the panel. You might want to also consider using a property grid. That way you can group things in logical categories and it would probably offer a less crowded interface for th...

If you're using 3.0 or later, wxString can be implicitly cast to const char*. So you can just do:
If the string contains only ascii characters, that's the easiest thing to do.

@PB thanks for the efforts, I will keep googling for OSX @New Pagodi QT somehow has done it https://doc.qt.io/qt-5/qwindow.html#fromWinId . anyway I don't see wxNativeWindow can help in this so will keep exploring, Thanks guys for your time. There's a lot of "ifs" in that description - I'm still sk...

I don't see any way this could work on macOS. In windows both top level windows and widgets are treated as the same sort of thing. On macOS top level windows and widgets are different things. wxNativeWindow is meant to wrap around the widget type objects - not the top level window type objects.

You need to handle the paint event.

The UpdateUI event is an entirely different thing that has nothing to do with drawing.

would it be possible (or just a good way to do this) to somehow determine the number of cpu cores in a system so I can create the optimal number of threads? The static wxThread method GetCPUCount should give you this number. if so, how many would be ideal? thank you! There's no way to answer this q...

Unfortunately no. Those files are the remnant of an attempt at an android port, but it never progressed very far.

Here's one way to do this. As discussed above, this uses a derived renderer and overrides the Render method. It basically just inappropriately injects a bitmap into the labels column and then calls the base class Render method. // For compilers that support precompilation, includes "wx/wx.h". #inclu...

That does seem like a pretty good approach. Other than the wxWidgets source code itself, you probably won't find any example code. If you can't make any progress, I'll see if I can throw something together tomorrow.

This is a really good question, but I don't think there is a good answer. Looking over the code, I think you might have to derive a class for each renderer you use and re-implement the Render method for column 0 to draw the check box and then the property label. You'll then need some way to keep tra...

Another thing that might trigger this error is trying to use the dynamic library when the static one was expected (or vice versa).

This is a wrapper around FFMpeg that sounds like it does what you want.
