Parameters

acontrol

ds

The new AnimationTTDatasource-object to attach to the extended property of acontrol.

Description

This method assigns the passed AnimationTTDatasource-object (ds) to the extended property provided to the specified control (acontrol) by the AnimationToolTip-component (ToolTipsFactoryAnimation). It is this object which holds the tooltip-content (and some other properties) used for the tooltip to be displayed for acontrol.

In the Visual Studio property-grid the access to the AnimationTTDatasource-object of a specific control is seamlessly integrated in the property-list of the specific control. (See the chapter on "Provided Properties" for more information.)

To assign a new or another instance of an AnimationTTDatasource-object to the extended property of a specific control through code, things are not exactly as one would expect: The AnimationTTDatasource-object is a property provided to a control by the tooltip component, and - if looking at the property-grid of the control - it definitely seems to be just a normal property of that control, but if you try to assign a new value to this property by code as to any other property of the control, you'll see that this is not possible, because the control does not expose such a property. Actually, the control, to which the tooltip-component provides this property, has absolutely no knowledge about this provided property, because this extended properties are managed by the providing component (in this case the AnimationToolTip-component). Therefore the programmatic access to this properties has to happen through the providing component.  And that's where SetAnimationToolTip() comes into play. SetAnimationToolTip() tells the tooltip-component to set the passed AnimationTTDatasource-object (ds) as new value for the property provided to the specified control (acontrol).

The following example shows how this could look in code:

 

'Create a new AnimationTTDataSource

Dim myToolTipDS As AnimationTTDataSource

myToolTipDS = New AnimationTTDataSource

 

'We assign new content (a movie-clip retrieved from

'database)

myToolTipDS.AnimatedSymbol = GetMovie("ChangeCartridge")

 

'And - because we know that this movie contains

'interesting details - we have to make sure that it is

'displayed with an appropriate size. For this,

'we override the DefaultWidth defined by the

'tooltip-component with an adequate value.

myToolTipDS.Override.DefaultWidth = 480

 

'Finally we can assign the new AnimationTTDataSource-object

'to the extended property provided to lblChangeCartridge

Me.videoTutorialTT.SetAnimationToolTip(Me.lblChangeCartridge, myToolTipDS)
