Some repainting when double-click on a `Compiler' error/warning.

#64 Some repainting when double-click on a `Compiler' error/warning.

Milestone: None

Status: pending

Owner: orwelldevcpp

Labels: None

Updated: 2013-10-28

Created: 2013-04-27

Creator: MikeDNC

Private: No

Dev-C++ version: 5.4.2 RC5

Steps needed to reproduce the problem:

Compile anything that gets one or more errors or warnings from the compiler. Double-click on an error or warning in the opened "Compiler"-output window. Use arrow keys to move the cursor around, and observe that both the Compiler-window-lines and all toolbars (Main, Edit, Search, etc) repaint ('flicker') each time the cursor moves.

This doesn't happen before I select one of the errors/warnings and then 'enter' it (double-click or press Enter) to send the text-cursor there.

It also goes-away once I close the Compiler window -- and then comes back when I reopen it.

Can't replicate for some reason. Still trying though.

Maybe I should specify I'm on Windows 7 Starter, SP1.
CPU: Really economy processor, but modern: Intel Atom. Each core is like a Pentium III.

I'll try to observe this on a Windows XP other Windows, with faster CPU too, tomorrow.

Well I finally got onto a faster machine, although it also has Windows 7 (64-bit in this case). I can still tell that the flicker is happening, although it's much less noticable or problematic. (This machine is > 5 times faster, a Core-i5-mobile).

I'll still observe this on a Windows XP soon.

I do sometimes notice it when I test responsiveness of Dev-C++ using a Phenom II X4 at 800MHz (still faster than an Atom :D). There is some really minor flickering in the bottom and left tab control. Toolbars are unaffected.

Hmm. Here are the exact locations of flicker, on the economy machine, with Dev-C++ 5.5.1 now. "Green" are the much-more-noticable areas; "blue" are less noticable. I wish I could get a video recording of the flickering to work right :) But we'll see if these match up to your described areas.

The 'bottom'-green circle (Compiler err/warning) is still by-far the most noticable flicker.

It's like the error/warning tab is being 'closed' (without being drawn closed) then redrawn, with each cursor-move.

Note that the error/warning line must be double-clicked, to enable the flickering-when-cursor-moved.
