SDL window size changed in Win32

SDL Development
1

Dear all:
I’m new to SDL programming.Recently I use SDL_1.2.7
to develop a video player in Win32 Dialog-based
Application. I hope the SDL window becoming a Dialog’s
child window,and it can chage the window size freely
according dialog window size.
I use SDL_SetVideoMode to set SDL-window size.When
SDL main window is a popup window,it works well.But
when I set the SDL window as the child window.of
dialog.The SDL_SetVideoMode seems only to change the
Video content,the window size keep unchanged.
For example,the original size of video and window is
320x240,when I SDL_SetVideoMode(640,480,…),the video
size is 640x480 now,but the window size is still
320x240,and show a 1/4 left-top video.
What am I missing?
Any information or hint are very appreciated.

this would indicate to me that you need to resize the parent yourself.
Child windows are always clipped by their parents. (i don’t know the
win32 api to do this, ask msdn)On 6/11/05, Renzhong Xiao <renzhong_xiao at yahoo.com> wrote:

Thanks for your response.But my parent window is
always maximized.So I don’t understand why need to
resize the parent.
BTW,whatever size I set using SDL_SetVideoMode,the
size of SDL video window (when embeded in dialog) is
always 320x240 (view by spy++).
