DeferWindowPos flags

[dedndave]

i understand most of what i read at msdn - lol
but, this one makes no sense to me

Code Select Expand

;SWP_DRAWFRAME      EQU 0020h
;Draws a frame (defined in the window's class description) around the window.
;
;SWP_FRAMECHANGED   EQU 0020h
;Sends a WM_NCCALCSIZE message to the window, even if the window's size is not being changed.
;If this flag is not specified, WM_NCCALCSIZE is sent only when the window's size is being changed.
fortunately, i am not using this (these) flag(s) for what i am doing now
but, i want to understand it (them)

also, this one for BeginDeferWindowPos makes no sense, either

If any of the windows in the multiple-window-position structure have the
SWP_HIDEWINDOW or SWP_SHOWWINDOW flag set, none of the windows are repositioned.

can anyone shed light on these ???

EDIT - one more question
exactly what does it mean to make a window "active" ?

Hi Dave,

When you change the border style of a window with SetWindowLong (GWL_STYLE) you have to recalculate the size of the windows non-client area since it will be slightly smaller or larger. If you don't use SetWindowPos with SWP_FRAMECHANGED the WM_NCCALCSIZE will not be sent and SetWindowLong will have no apparent effect. For SWP_DRAWFRAME, the frame of a window is the border style, for example sunken or 3d, when you use it with SetWindowPos it forces the window to redraw its border (non-client area). For DeferWindowPos, I think I sent you an example of how to use it once, not completely sure if it was you though. DeferWindowPos has a few restrictions, like the ones you mentioned but as I always say "real men use DeferWindowPos, the rest use MoveWindow"  :bg. Seriously though if you have more than two windows to resize or reposition, DeferWindowPos is the best way to accomplish it.

thanks Edgar
as i said, i am not using these flags   :bg
but, the real question is, how can they have such different descriptions, yet they are the same pin   :dazzled:

this is something like you might expect to see

Code Select Expand

;SWP_NOOWNERZORDER  EQU 0200h
;Does not change the owner window's position in the Z order.
;
;SWP_NOREPOSITION   EQU 0200h
;Same as the SWP_NOOWNERZORDER flag.

thanks Andreas - i knew it was in there someplace - i just couldn't find it   :P

[dedndave]

by the way
yes, Edgar - that was me   :U

i am using DeferWindowPos to answer WM_SIZE - actually, that part isn't too bad
here are the pins that i plan on using - i may play with them to see what yields the best results

Code Select Expand

SWP_NOZORDER or SWP_NOACTIVATE or SWP_NOOWNERZORDER or SWP_NOSENDCHANGING

i figure anything i do to help the function be faster is a good thing
no change in Z-order
no activate - if they are sizing the window, it's already active
no send - i don't handle the WM_WINDOWPOSCHANGING message - no need to send it   :bg

Dave,
I always defer to Edgar, when the problem involves anything Windows-related, he's omnicient,...
But, if you want a second opinion,...here is: What's the point of DeferWindowPos?, by Raymond Chen.

thanks Baltoro
that made for an interesting read
