[Delphi] How can I avoid overwriting the taskbar when the window is maximized?

Method 1:

Set the align attribute of the form to be full screen to alclient. This method is the fastest.

Note that the form windowstat should be set to wsnormal. If it is set to wsmax, some will be blocked.

Method 2: UseCodeControl. In the form creation event (after this method is run, the form can also be moved. Affect appearance. Code that prohibits form movement should be added) Write

VaR traywnd: hwnd; // taskbar handle REC: trect; begintraywnd: = findwindow ('Shell _ traywnd ', nil); // obtain the taskbar handle getwindowrect (traywnd, REC ); // obtain the dimension mainfm of the taskbar. left: = 0; mainfm. top: = 0; mainfm. width: = screen. width; mainfm. height: = screen. height-(Rec. bottom-Rec. top );

In this way, the full screen mode does not block the taskbar.
