Summary0006005: When using TJvBalloonHint as application hint, the MaxWidth is not respected
DescriptionWhen setting the property 'TJvBalloonHint.UseBalloonAsApplicationHint' the actual hint window will not respect the 'MaxWidth' property of TJvBalloonHint.

As workaround you can place a 'TApplicationEvent' component on the form a supply the maxwidth using the 'OnShowHint' event (pointing to the TJvBalloonHint Instance).

But this should be read by the TJvBallonHintWindow itself, through the GlobalCtrl in the JvBalloonHint unit.
TagsNo tags attached.

Inside VCL.Forms.pas, have a look at TApplication.ActivateHint
You'll see that it initializes the maxwidth like this:

HintInfo.HintMaxWidth := Screen.Width

but the HintInfo structure is never given to FHintWindow before it gets a chance to be displayed. The only chance anyone has to change the HintMaxWidth property is via the OnShowHint event handler.

Using a private TApplicationEvent did the trick.
