IXRUIElement::InvalidateMeasure (Windows Embedded CE 6.0)
1/6/2010
This method invalidates the measurement state, or layout, for this UI element.
Syntax
virtual HRESULT STDMETHODCALLTYPE InvalidateMeasure() = 0;
Parameters
None.
Return Value
Returns an HRESULT that indicates success or failure.
Remarks
You can call this method when a child object of this UI element's parent object is added or removed, and it is necessary to invalidate the current measurements and resize the children objects. For example, call this method on a UI element arranged on a panel when you remove items or insert items in the collection that belongs to an IXRPanel object.
Calling this method also calls IXRUIElement::InvalidateArrange internally, so there is no need to call InvalidateMeasure and InvalidateArrange in succession. After the invalidation, the element will have its layout updated, which will occur asynchronously, unless IXRUIElement::UpdateLayout is called to force a synchronous layout change.
