Window size differences

[xyzzy]

This might have been mentioned before, but different XP themes seem to have an effect on the vertical size of the client area

For example, I have this window set to 640 x 480


In Luna, it looks like the client area is 481 pixels tall, but in classic theme it's 479. I haven't noticed any problems with the horizontal size.

Also, is there a way to resize the client area at runtime? Right now I have the frame set to resize to the screen size at start, which works, but it leaves some of the frame covered by the title and menu bars.

resize the client area at runtime by using the normal window resize.

You can calculate window y size - client area

Then when resizing just set the window size to "client size" + x

with "Sphax Kernel object" you can retrieve window size and client area size and position so you can calculate a correct size for your client area.

Interesting, I thought this was common knowledge.

To help other developers I added a page regarding this issue to the wiki here.

You'll need to read it to get up to speed regarding this issue, it a little more comprehensive and covers more aspects of what can affect the client area.

Your article has also inspired a new category at the ClickWiki called Debugging Applications.

Thanks.
