Prevent resizing of a MDI-Child (OpenInsight 32-Bit)

Hi,

How can I make a MDI-Child replaceable but with a fixed size?

I tried the orig_size but this property gives negative values in the height en width fields.

tnx

You could set the Frame Type (in Window Properties) to "Thin"

The Thin setting works in testrun.

But when i launch the window with start_mdichild() the Thin setting doesn't prevent the resizing :-(

Ed,

Regardless of the frame settings you choose for your child forms Windows always overrides them and uses a thick border. This is so that the child can within the MDI Client area and have the ability to be minimized, maximized, tiled, cascaded and so on.

There is a way that you can prevent normal windows resizing by using the WM_MINMAXINFO message but I haven't tested it on an MDI child window to see it's effects. It was covered as part of the RevConference presentation we did at New Orleans last year - If you're interested please drop us a line as it's not been published on our website yet.

Should have read …

I put in the createvent of the window:

designstyle=@WINDOW-]ORIG_STRUCT$

@window-]style$=designstyle

this works….

Ed,

Good idea :) I remember trying this back in the days of OI16 when I needed something similar to simulate tabbed windows via an MDI frame, but this caused various problems.

I've actually just tried this again on OI7.1 and I get some strange behavior when trying to access the MDI menu and frame controls. It almost seems that the Child is behaving like a dialog box and blocking it's parent. There's also some frame redraw issues. Do you see this?

Sprezz,

Nope, but i left the path of the style-override.

I now save the size during create in my own @CREATESIZE.

In the size event the width is reset to @CREATESIZE.

Actually i only want the width frozen, the height must be resizeable in some cases.

Thanks
