|0005759||[JEDI VCL] 00 JVCL Components||major||always||2012-01-03 15:44||2012-09-10 14:15|
|Status||resolved||Product Version||Daily / GIT|
|Summary||0005759: Cell hint is shown in wrong position|
When ShowCellHint = True hint is shown always in the top left point of the cell and not at the mouse cursor position.
Why it is performed this way?
if not AtCursorPosition and HintWindowClass.ClassNameIs('THintWindow') then
HintPos := ClientToScreen(CursorRect.TopLeft);
Why not Mouse.CursorPos?
I think hint must drop down where is mouse cursor andnot in the another side of the screen (if cell is bigger than 16 pixels...).

|I forgot to tell.. :) It's JvDBGrid.pas, sorry.|
Is there someone alive? :) Just check a patch and apply it if it is correct.
Or probably we can invent a property (bicycle :) ) for defining how hint is displayed - below mouse cursor or in the top-left corner of grid. I just checked how it is in DC++ (RevConnect) software - they display the hint in top-left corner.
So maybe a property like:
TJvGridCellHintPosition = (chpDefault, chpMouse);
And then in appropriate place we select how to display the hint.
|Please provide the zipped sources of a sample application showing this|
When you move mouse over the right corner of the first cell, hint is popped up at top left corner. Which maybe is a default of course, but sometimes is very weird.
Just read my comment about possible property..
Truly, i disliek how most GUI libraries tend to use Mouse.Pos.
Win32 plain API was much more correct here.
For many times i saw some application frozen for a second or two, and then menu or hint popped up at completely different place (since mouse moved suring those seconds)
I would also say that there are large cursorls, like those by Stardock CursorFX, so that hints "under cursor" got really hidden by that very cursor.
I do not know if complete and reliable solution can be made in frames of VCL, but it is not just so easy...
Regarding this particular case, i suspect the goal of hint was not just to react to mouse, but to show the complete cell value, when it is too narrow to render the whole text. Cell may display like "abcd...xyz" while the hint would render the hole alphabet. From this POV following mouse cursor is not that obvious choice.
|That's why I suggested the property for that choice. And by default make it as it was before.|
|I uploaded "Property solution - JvDBGrid.pas.patch". There I added a published property named CellHintPosition of type TJvDBGridCellHintPosition (gchpDefault, gchpMouse), by default it is as it was before. But now if you set to gchpMouse then hint appears under mouse cursor.|
|Thanks, this is now in SVN|
