gtk4-demo: Use #pragma once consistently This is our current coding style. 2023-12-20 14:55:11 +00:00			`#pragma once`
gtk-demo: Add GskGLShaderNode demo Add adds a demo showing off GskGLShaderNode in various ways. It has a transistion widget, using some examples from gl-transitions.com, with child widgets being both images, a GL area and real widgets (that let you edit the transition shaders themselves. It also has a fancy fire effect on hove on the buttons. 2020-09-21 19:05:04 +00:00

gsk: Deprecate GskGLShader and the rendernode The new renderers don't support them due to the required complexity of integrating them with Vulkan and the assumptions those nodes make about the renderer (the GL renderer exports its internal APIs into the GLShader). There haven't been any complaints that I'm aware of since 4.14 was released where the default renderer does not support the nodes, so usage in public seems to be close to nonexistant. The 2 uses I know of were workarounds about missing features in GTK that have stopped since GTK now supports them: 1. GStreamer used in to do premultiplication when the old GL renderer did not do so in hardware but on the CPU. 2. Adwaita used it for masking before the mask node wa added in 4.10. 2024-07-04 16:12:16 +00:00			`G_GNUC_BEGIN_IGNORE_DEPRECATIONS`

gtk-demo: Make gltransitions demo a bit snazzier This adds a bunch of snazz to the gltransitions demo. It is perhaps a bit overloaded now, but it demos everything that we can do. Changes: * The fire shader is now not a bin, it just renders an animating background with no textures involved. * The stacks don't all start on the same page. * The shaderbin passes the mouse coordinate to the shader. * The shaderbin allows specifying a "border" so that you can cause effects outside the bin child (something that is new to gtk4). * All the buttons and the stacks are now in shader-bins that runs a wobbly-widget effect based on the mouse position that wobbles outside the child allocation. 2020-09-30 09:40:37 +00:00			`GtkStateFlags state_mask,`
