Console is shown at startup Topic is solved

[Klaus82]

I have the problem that the console is always shown on startup before the wxFrame is shown.

When I compile the shipped minimal sample, it does NOT show the console at startup, but when I write an own application (see code below), the console is shown before the wxFrame is visible. It looks like a wxAppConsole which creates a wxFrame.

Do I have to add a define or something else?

        return false;
    MyFrame *frame = new MyFrame("Minimal wxWidgets App");
    frame->Show(true);
    return true;

Have you tried adding -mwindows to the linker flags?

[Klaus82]

That was the problem. I added the linker flag to my cmake file:

Code: Select all

SET(CMAKE_EXE_LINKER_FLAGS "-mwindows")

Thanks a lot.
