Check/disable/dispatch window commands in GameMaker · By
1. A way to automatically prevent the window from opening off-screen.
2. A way for the window to automatically snap to the edges of other windows.
3. A way for the window's title to appear in the center of the title bar, instead of on the left of it.
4. A way to hide the standard window controls and window border, and instead use custom ones.
You can do that yourself using window_ and display_ functions; I wrote an extension that can return workspace areas (read: excluding taskbar areas) for each screen (also included in Dekstop Screenshots).
Based on fact that most third-party software for competently snapping windows to edges of other windows costs $30 and more, I’m willing to assume that this is not as easy as it sounds.
It is possible to override WM_NCPAINT to do various strange things with window border, but in doing so you open yourself up to a lot of potential compatibility issues across different versions of Windows, themes, and custom desktop managers (like Stardock’s WindowBlinds). Doing so just for a centered title is uncommon.
You can disable the window border in Game Options - Windows - Graphics, and then draw your own as you please; This extension offers simple 1-bit transparency if you need rounded borders. GMS1 includes with a small demo project on implementing custom frame movement/resizing on Demos tab.
Looking back through the threads, I did make an extension for custom border+controls later on.
