C ++ WINAPI-绘制无边界的ListView

Question

I'm having a little trouble.

For parent window I used dimensions 920x570. For ListView 900x500.

Viewing at this dimensions, one would say there are quite some borders, however it is not like that in reality. If I use exactly the same dimensions I get quite a big part of ListView cuted off. Well I could try to find exact values which will give me "borderless" ListView, but even when I do so thing is slightly different in Windows XP (we are talking about 5-10 pixels).

Is there right way to draw ListView "borderless" natively to work on all platforms?

They say picture is worth a thousands of words... so here it goes

You have to distinguish between window size and client size. If your parent window is 920x570, then these are its outer dimensions. Client area is smaller and that's what you need to set your listview's dimension to to make it fit nicely in the entire area.

Have a look at GetClientRect function. You need to set ListView's dimensions to those you get using this funcion.

EDIT

Your code could look as follows

HWND outerWnd = CreateWindowEx(...);
RECT clientRect;
GetClientRect(outerWnd, &clientRect);
HWND listView = CreateWindowEx(..., WC_LISTVIEW, "", WS_CHILD|..., 0, 0, clientRect.right, clientRect.bottom, outerWnd, NULL, hInstance, NULL);

With GetClientRect , right and bottom members of RECT struct are width and height of the window, respectively.
