This method retrieves a value that represents the actual rendered width of this column definition.
Syntax
virtual HRESULT STDMETHODCALLTYPE GetActualWidth(
float *pActualWidth
) = 0;
Parameters
- pActualWidth
[out] Pointer to a float value that represents the actual rendered width of this column definition.
Return Value
Returns an HRESULT that indicates success or failure.
Remarks
The value of pActualWidth is a calculated value that is based on other width inputs and the layout system.
When you add or remove rows or columns to a grid object, the ActualWidth value for all IXRColumnDefinition objects, and also the ActualHeight value of all IXRRowDefinition objects, becomes zero until the IXRGrid inherited method IXRUIElement::Measure is called to update the desired size of the object.
