Somebody else told me that before. But I needed more flexibility by changing the appearance of a _single_ component on-demand (eg: TEdit's background to clError [yellow] when there was a validation issue). All this is water under the bridge for me now - we are already 2.5 years into development. Why to late to change GUI toolkits again. I implemented this in another way: when i need to show where user entered invalid data (f.e. TEdit) i simply draw animated frame around that control (for this i writted component "error shower": at startup they collect all TControl's with "error showing feature", and at runtime i tell for him where need error to show).

Re: "cannot find -lGL" (OpenGLContext application)

I am just guessing; but it is not linking in the GL library. is it -LGL instead of -lGL?, also just try -L GL? I think that you are very close.. the next error should be; cannot find library GL The linux linker is very pedantic - keep trying First check if library "libGL" is installed: open console, execute "cd /usr/lib" to goto in that dir then execute "ls libGL*". If in output you see words like "libGL.so.1.0.9639" - library is installed, otherwise you need install this library. If library is installed but you not see "libGL.so" in "ls" output then you need make symlink from "libGL.so." (in my example "libGL.so.1.0.9639") to "libGL.so": execute in that dir command "sudo ln -s libGL.so. libGL.so". -- Valdas Jankūnas _ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
Re: [lazarus] FSAA with TCustomOpenGLControl

Re: [lazarus] Color detector program
Graeme Geldenhuys rašė:
Hi,
I would like to implement a color detector program.
...
Anybody working on something like this? I've seen loads of these
applications for Windows, but I need something like that to work under
Linux too. Any thoughts on how you would implement something like
this? I guess looking at Felipe's magnifier application should yield
some clues.
My thoughts: first get desktop screenshoot and then get pixel color of
that shot at mouse coordinates.
Or look at GColor2 ("http://gcolor2.sourceforge.net/";) color picker
sources.

"Level 3 (-O3) equals level 2 optimizations plus some time-intensive
optimizations.". And in this dialog also is checkbox "Uncertains

Re: [lazarus] TSpeedButton bugs patch
Giuliano Colla rašė: It's soon explained. The patch reverts this portion of code to the situation which has been working for a long time (see rev. 10808 - ver. 0.9.22 - which btw already had the speedbutton.inc bug). Someone, with the good proposition to improve it, added an unnecessary modification of the destination rectangle. It's unnecessary, because previous calculations already center both glyph and text in the widget client area, and subsequently the resulting image is properly clipped against widget's client area. Unfortunately, he/she did it wrong. If you increment the Right property, and decrement the Left one, you decrease the rectangle area, up to make it negative. The same holds true for Top and Bottom. Removing the "improvement", Text and Glyph are properly positioned, properly centered, and properly clipped if they don't fit. It's easy to check just from the IDE.
