You usually call Bind on the object generating the event you want to handle. Since the frame is the object generating the size event, you should call

I'm not sure what your asking, but here's an very simple example of how you can use the same code file in 2 projects with codeblocks. I created a console application and a wxWidgets application in the same folder. Then I used the new file wizard to create a c++ header and a c++ file named class.h an...

It sounds like you should be using libtiff directly instead of wxWidgets wrapper for it.

The development tools supplied by apple use the clang compiler. It is capable of compiling c,c++, objective c, and maybe others as well. You only need to use objective c if you want to work directly with the system libraries. As far as gui programming does, on macOS, wxWidgets is basically a c++ wra...

To rotate an image by angle α about a point P(x0,y0), you translate by (-x0,-y0) perform the rotation translate back by (x0,y0) So if you have an image that has already been rotated about a point and you want to get the original point, you just undo those operations: translate by (-x0,-y0) [this und...

You need to match the wizard's options to the settings you specified when building the library. Since you said you used the build command mingw32-make.exe -f makefile.gcc USE_XRC=1 SHARED=1 BUILD=release UNICODE=1 make sure "Use wxWidgets dll" and "Enable Unicode" are checked and the option about a ...

If you're using codeblocks, just use the wizard to create a new wxwidgets project. The wizard will configure all of the include/lib folders for you. You don't need to make any changes to your system's environment variables to use it.

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.
