| Summary | 0006005: When using TJvBalloonHint as application hint, the MaxWidth is not respected | ||||
| Description | When 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. | ||||

JVCL BUG - TJvBalloonHint MaxWidth.rar (91,352 bytes) |
|
|
Demo application supplied CheckBox activates the described workaround using ApplicationEvents object |
|
|
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. |
