    Add wxGLCanvas::SetSwapInterval() and GetSwapInterval()

Allow setting the swap interval value or not setting it at all instead
of always forcing it to 0.

The changes of 3dde6bdeb0 (Disable swap interval in GLX wxGLCanvas
implementation too, 2023-12-25) are not always desirable, so allow to
customize the behaviour.

Implement this for Unix (GLX and EGL) backends for now and allow testing
using these functions in the cube sample.

See #24163, #24165.

    Check for GLX_EXT_swap_control availability

glXSwapIntervalEXT() might exist in the client library but not be
actually supported by the driver, so check if it advertises the
extension defining this function.

Also don't query GLX_SWAP_INTERVAL_EXT if this extension is not
available as it would generate an X error.

    Fall back on GLX_MESA_swap_control if GLX_EXT_swap_control is NA

Try using the older extension if we don't have the newer one.

    Remove unused WXGLSwapBuffers() function

This seems to have never been used in Cocoa wxOSX version and is
definitely not used currently.

    Implement support for wxGLCanvas swap interval in wxOSX

Just use NSOpenGLCPSwapInterval parameter for this.

    Implement support for wxGLCanvas swap interval in wxMSW

Just call the corresponding WGL_EXT_swap_control extension functions if
available.

    Add support for requesting adaptive VSync to wxGLCanvas

Mimic the low level OpenGL APIs by allowing to pass -1 to
SetSwapInterval() to request adaptive VSync and implement this for GLX
and WGL.

Change return type of SetSwapInterval() to allow returning a value
indicating that enabling adaptive VSync failed but standard VSync could
still be set.

    Call wxD2DContext::EnsureInitialized() only once

It seems useless to call it again as it effectively does nothing after
the first call (just reassigns the same value to m_cachedRenderTarget).
  • 59b45116
    by Vadim Zeitlin at 2026-02-07T19:19:16+01:00 
    Rename wxD2DContext::m_cachedRenderTarget to just m_target

Also use it instead of repeatedly calling GetRenderTarget() in
EnsureInitialized().

No real changes.

    Handle errors in wxD2DRenderer::CreateContext() better

Don't assert and then crash if BindDC() call fails, just returns a null
context pointer instead and let the application to deal with it.

Closes #26052.

    Add move constructor to wxWindowDisabler class

Will be needed when we add modal window support to wxFrame in the
upcoming commits. i.e.: construct wxWindowDisabler objects directly
in a std::stack<>.

    Re-define wxPreviewFrameModalityKind as an alias to wxFrameBase::ModalityKind

and keep it to maintain backward compatibility.

    wxQt: Override wxFrameBase::SetWindowModality()

Quoting the Qt documentation (QWidget::setEnabled()):

	Disabling a widget implicitly disables all its children. ... It it not
	possible to explicitly enable a child widget which is not a window while
	its parent widget remains disabled.

This means implementing window modality using wxWindowDisabler(winToSkip) to
make winToSkip behave like a modal window to the application, or as a modal
window to its parent (by just disabling the parent window) WILL NOT WORK in Qt
and this is by design. IOW, wxWindowDisabler always disables everything in wxQt.

    Allow running tests from MSVS in DLL configurations

Create file tests/tests.props which adds the DLL build directory
to MSVS PATH in <LocalDebuggerEnvironment> property and add the
file to test.vcxproj and test_gui.vcxproj MSVC projects.

See also eba106431a (Allow running samples from MSVS in DLL
configurations, 2024-11-14).

Closes #26171.

    Document that wxApp::OnExit() should be called from overrides

And update the samples to follow the advice in the documentation.

Closes #26173.
