Question

如何使用Windows API创建一个窗口总是位于屏幕最上方

Answer 1

创建置顶窗口： CreateWindowEx( WS_EX_TOPMOST, ......
如果在创建窗口以后，置顶 ::SetWindowPos(hwnd,HWND_TOPMOST,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE)
取消置顶
::SetWindowPos(hwnd,HWND_NOTOPMOST,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE)
用AAuto写个示范：

import win.ui;
/*DSG{{*/
var winform = win.form(
text="置顶窗口测试";
right=449;
bottom=203
)
winform.add(
checkbox={
cls="checkbox";
text="置顶此窗口";
left=109;
top=92;
right=352;
bottom=126;
z=1
}
)
/*}}*/

winform.checkbox.oncommand = function(id,event){
win.setTopmost(
winform.hwnd,
winform.checkbox.checked
)
}

winform.show()
win.loopMessage();
