Summary0010330: misplaced code-completion hint on windows, with desktop across multi-monitor
DescriptionOn Windows (vista) if your gfx card support more than one monitor, set up 2 screens. Declare the right screen as your main screen, the left screen as secondary.

Now any window on the left screen has negative coordinates.

The IDE-code editor does not deal correctly with this, if the source editor is on the left screen and asked to display code completion hints (ctrl-space).

The hint is not displayed at the correct location (which would have a negative x-coordinate), but instead the x-coordinate is set to 0 => the hint is displayed at the left-most position of you main(right) screen.

Additional Informationsimilar errors can be seen with other hints for example in debugging, holding the mouse over a symbol
TagsNo tags attached.

The issue also applies to the restoration of Windows after restart, changing projects ....

While normally The position of all your windows is stored / and restored (while loading a project), any negative coordinate that a window may have had is set to zero

Negative screen coordinates, who would have thought about that :-(

Just found more (windows vista / home premium / 32 bit nvidia gfx card / both screens have the same resolution)

I have swapped my screens, so that now my Left screen is the main screen. And the right screen acts as 2ndary (but has positive coordinates now)

Now any window on the right (2nd) screen, has it's hints limited to the main screen. They are displayed at the right most position. (the right side of the hint win is aligned with the right site of the main screen)

I guess there is some code, that makes sure the hint is not shown (or part shown) outside the screen (like if your screen was 1200 pixel, the hint can not be at 1198, as you would only see 2 pixel of it)
This code takes the width of a single screen, and is not aware of the fact that I have a 2nd screen.

BTW, I have no idea how that would have to be handled, if the 2nd screen was of smaller size, as then the total width would depend on the y position:
1st screen 1200*1024 / 2nd screen 1024*768 =>
 if y < 768 width= 1024
 if y > 768 width= 2224

As I said my screens are both the same size.
