How do you programmatically resize and move windows with the Windows API?

Question

How do you programmatically resize and move windows with Windows API?

The scenario is: I want to vertically tile two windows (80%/20% width proportions).

Answer 1

For flicker-free, simultaneously positioning two (or more) windows, your best bet is to use BeginDeferWindowPos() , DeferWindowPos() and EndDeferWindowPos() . In your case, since you're moving two at the same time, this is your best bet.

Three older, simpler functions you might also consider are SetWindowPos() , MoveWindow() and AdjustWindowRectEx() .

Answer 2

Use SetWindowPos() in the Windows API.

Given a HWND, you can change the z-order, position (upper left), size, as well as numerous other flags (like showing or hiding, making it the active window or not, etc).

Answer 3

You're looking for one of SetWindowPos , MoveWindow and AdjustWindowRectEx .

Can you be more specific about the scenario so that we can recomend the most appropriate API?

Answer 4

SetWindowPos或MoveWindow将为您完成此任务

Answer 5

在SDK文档中查找MoveWindow 。
