The following code example provides a PropertyValueUIItem object for any properties of the component named HorizontalMargin or VerticalMargin. The PropertyValueUIItem for these properties provides an image, a ToolTip, and an event handler that displays a message box when the image for the property is clicked. This code example is part of a larger example provided for the IPropertyValueUIService interface.
// PropertyValueUIHandler delegate that provides PropertyValueUIItem // objects to any properties named horizontalMargin or verticalMargin. void marginPropertyValueUIHandler( System::ComponentModel::ITypeDescriptorContext^ /*context*/, System::ComponentModel::PropertyDescriptor^ propDesc, ArrayList^ itemList ) { // A PropertyValueUIHandler added to the IPropertyValueUIService // is queried once for each property of a component and passed // a PropertyDescriptor that represents the characteristics of // the property when the Properties window is set to a new // component. A PropertyValueUIHandler can determine whether // to add a PropertyValueUIItem for the object to its ValueUIItem // list depending on the values of the PropertyDescriptor. if ( propDesc->DisplayName->Equals( "horizontalMargin" ) ) { Image^ img = DeserializeFromBase64Text( imageBlob1 ); itemList->Add( gcnew PropertyValueUIItem( img,gcnew PropertyValueUIItemInvokeHandler( this, &PropertyUIComponent::marginInvoke ),"Test ToolTip" ) ); } if ( propDesc->DisplayName->Equals( "verticalMargin" ) ) { Image^ img = DeserializeFromBase64Text( imageBlob1 ); img->RotateFlip( RotateFlipType::Rotate90FlipNone ); itemList->Add( gcnew PropertyValueUIItem( img,gcnew PropertyValueUIItemInvokeHandler( this, &PropertyUIComponent::marginInvoke ),"Test ToolTip" ) ); } }
