Can't get tooltips to display (Read 10845 times)

	I'm working with Delphi (v4) on Windows XP. I can't get tooltips to display for either boxes or arrows. I've explicitly set .ShowToolTips to true and .ToolTipDelay to 500. Other than actually setting the .ToolTip property of the box/arrow, is there any other magic spell I'm supposed to cast?

	It seems the Hint property that Delphi adds somehow breaks the flowchart's tooltips. We haven't found how to prevent this yet.

	OK. At least it's not me doing something dumb this time.

	The flowchart tooltips work fine if you call the Application.CancelHint() method. I suppose that might be a problem if you need to display hints for other elements on the form.

	At FormCreate or FormShow - both worked for us. However we have only a flowchart control on the form. If that hint is automatically activated by other controls, you might have to call CancelHint somewhat more often, say from a mousemove or timer event

	I can't get it to work here (Delphi 4, if that makes any difference) I've added Application.CancelHint calls to the FormShow event and to the OnMouseMove event of the form.

	Well, we used the latest Delphi version from the Codegear site, and don't have any idea where to get Delphi 4 from. If we suppose that the Delphi 4 hint somehow destroys the flowchart's win32 tooltip control, then setting flowchart.ShowToolTips = true after calling CancelHint might restore it.

Sadly it doesn't Bugger! If a copy of the D4 installation disk magically turned up in the post, do you think you'd be able to investigate further?

	Stoyan, I'm struggling to get hold of a copy of the D4 installation media. Whilst I work on that, could you send me the code for the Application.CancelHints method from the VCL in the version of Delphi you do have please? Ta.
