wxWidgets Discussion Forum

You don't post any code, so I can only guess about your issues using the few and hidden clues you give. I have a very simple system that spawns some windows that use the wxGLCanvas class only to paint their bodies. They have a few handlers for input and Size/Move events. This works for MSW. Under GT...

I assume X11 is a subset of GTK, since all Linux desktops use x11 protocols. No. I think you should read the X11 guide slowly, again and again until you got it. Pay attention to "Display" "Window" "Map window" "Visual" "Color", "Event" and those X11 concepts, which sometimes -but not always- are th...

Take a slow look at yourwxBuilDir /samples/minimal/Makefile . It defines a var wx_top_builddir and another top_srcdir = ../../.. top_srcdir is "yourwxMainDir" = /home/fc/wxWidgets/wxWidgets-3.0.4 in your case. You have two different wx builds (I called 'yourwxBuilDir') /home/fc/wxWidgets/wxWidgets-3...

I think you should review the link directories you set in C::B for different targets. And likely the include dirs also.

wxFrame (or wxWindow in general) has some useful functions: //The length of the text wxSize sL = GetTextExtent(FileDialog1->GetPath()); //The size of the client part of the window. wxSize sC = GetClientSize(); //Replace width sC.SetWidth(sL.GetWidth()); //New client size SetSize(sC); Layout(); Inser...

You may better ask in Code::Blocks forum http://forums.codeblocks.org/

A small hack that I used with TDM GCC 5.1: Edit include/wx/window.h , about line 1700, add the #if block: wxDEPRECATED_MSG("use SetInitialSize() instead.") void SetBestSize(const wxSize& size); #if !wxCHECK_GCC_VERSION(5, 0) wxDEPRECATED_MSG("use SetInitialSize() instead.") #endif virtual void SetIn...

Both wxWidgets and C::B try to keep old environment (compiler and wx versions, and MSW / GTK olds too). This means some sort of surprises, as the warnings you get, or some controls having different behaviour in different MSW versions. Normally you can develop e.g. for Win7 and everything goes "well"...

There are two main "adaptions" of GCC for Windows: MinGW and Mingw-64, the latter was a fork from the former. They have different web sites. Both use GCC 8 . Up today, Mingw is only capable of build 32 bits binaries (they are working on a 64 bits version), while mingw-64 is 32/64 capable (look for -...

I think you want the icon not of the file, but of the application used to open that file.

Look for wxFileType::GetOpenCommand(). Extract the application from the command, then retrieve the icon for that app.
For the second part, I don't know the clue; something in the Window's registry I guess.

A thread executes code, no matter where it's written. So, calling a GUI function or event-handler or whatever from a thread will execute that code as if was written "inside" the thread's code. An event handler receives events, comming from the OS or from [your] code, and stores them in a list. Latte...

wxDataViewCustomRenderer::Render() uses the wxDC to draw directly (as you would do by wxDC->DrawLine, or DrawCircle, etc). To draw text use wxDataViewCustomRenderer::RenderText() . For a combox box, wxDataViewChoiceRenderer For other targets, there's already some good classes. Take a look for wxDat...

Those are harmless warnings.

Anyhow, if you want to get rid of them, then choose a more recent compiler. You need GCC > 5.3. TDM is, by now, 5.1

I don't see anything else wrong in your code. And wxWidgets OpenGL stuff is quite simple. However, there have been some changes in the last two years that may be part of your issue. If the opengl/cube sample (or any of the other opengl samples) doesn't work neither then please open a ticket at https...

Some comments. Using the display attribute Depth(32) may not work for some old cards (where maximum was 24). You should first check if it's valid with wxGLCanvas::IsDisplaySupported(attrs) . When the window is resized you just call glViewport , but you don't force a redraw. If you think the style wx...
