Custom Popup Window for Windows OS
#1
This program required Win32 API calls, so it will only run on a Windows system.

Custom window in that the code generates a small borderless window text window and adds a custom menu plus drag to move and drag to resize features. It does NOT use the QB64 RESIZE commands but does make use of the mouse cursor appearance changes. Thanks a ton to the dev who provided that neat QB64 mouse feature.

The top pseudo-title bar is functional. The three horizontal lines represent a pop-open menu. Click to open. The menu options are mostly for demo only, but close and quit do work. The symbols from top left to right are "-" Minimize, [] Fullscreen, and "X" Close.
