I agree that it is not good practice to move the mouse pointer programmatically... However, I want the behavior of using the wheel to zoom (in/out) with the position of the cursor determining which part of the image/diagram should be shown in the center of the window. So if I want the see the upper...

If you want to draw with transparency with wxGraphicsContext while caching the result in a bitmap, I would try adding a function like this: void CAnalysisPanel::BuildPlot(int width, int height) { wxImage img(width,height); // Create an alpha channel and set all pixels transparent. img.InitAlpha(); m...

New Pagodi: yes, this seems the classical approach and I probably stay with it, it also allows me to cache separate bitmap for more plots and then just compose them when needed. Although the usage seems much more complicated, e.g. how to plot the lines into the transparent wxMemoryDC so I can compo...

I think a better approach would be to cache the plots into a bitmap. The paint handler would first draw the bitmap and then draw any extra lines over the bitmap. To generate the cached bitmap of the plot, you can use wxMemoryDC.

I believe the problem is due to this issue. According to the ticket, the workaround is to call SetPointSize after creating the font.

My gut feeling is that in order to debug a program that has used the Visual Studio Build Tools compiler (cl.exe), one requires the Visual Studio Debugger, and that no matter how hard I try, gdb won't understand the debugging symbols,etc produced. However as the VS debugger is only available in Visu...

If you call
subsequent search operations will be case sensitive.

I agree with doublemax. I think libvlc is your best (and maybe only) possibility.

You can convert a unicode code point to a wxUniChar . Usually unicode code points are listed in hexadecimal. To take your example, decimal 61 is 0x41 in hexadecimal, and you can look up that the unicode code point is U+0041 listed as "LATIN CAPITAL LETTER A" . You can create this a wxUniChar for thi...

This sounds like this issue. It was recently fixed. If you can, try using the latest version from git. If that's not an option, try using CallAfter as discussed in the first comment on that ticket.

If your issue still happens with the latest version from git, open a new ticket.

Sorry, no lexer currently supports this. There was a recent discussion on the Scintilla list about this very question.

I haven't tried it with soundfonts, but usually you can pass the same command line options to libvlc that you can pass to the VLC exe. (In the call to libvlc_new). https://wiki.videolan.org/VLC_command-line_help --soundfont=<string> SoundFont file For some reason, that doesn't seem to work. What I ...

It looks like vlc will play midi files and that would probably be a better cross platform approach anyway.

However you need to specify a soundfont file. With the vlc binary this just requires setting an option. I cant quite figure out how to do this through the libvlc interface.

[/code]The RGB values must be pre-multiplied with alpha. writeIt.Red() = readIt->r * readIt->a / 256; I don't know if this matters, but the way building a wxBitmap from RGBA data is done in the wxSTC source is p.Red() = wxPy_premultiply(red, alpha); p.Green() = wxPy_premultiply(green, alpha); p.Blu...

No, I'm talking about native boxes where the user can input data themselves, not wxStaticText. Just like in the Blender picture above. One way to do this using the renderer/editor division of labor. wxWidgets uses this for wxGrid, wxDataViewCtrl, and wxPropgrid. The idea is to bring up the editor (...
