How to disable pull-down menu entries in OIP widgets?

[Stefan Bender]

Dear developers,

 

in one of our PIOs I will need to disable/dim several pull-down menu entries in an OIP widget. The widget is created automatically (it represents a kFieldPopUp field of the PIO record). I don't want to disable the entire widget, just some of the pull-down menu entries depending on the PIO's setings. Does anybody have an idea? 

 

Thanks for any help.

Hi Stefan

 

I'm not sure it will work in your case because we create our widget via:

void IProviderShapePane::Init(CodeRefID objectID, IExtendedProps* extProps)
{
	IWidgetsEditProvider*	widgetsProvider	= NULL;

	if ( extProps && VCOM_SUCCEEDED( extProps->GetObjComponentTypeWidgets( objectID, kObjectRootComponentTypeID, widgetsProvider ) ) )
	{
		widgetsProvider->AddWidget( kWidgetID_SizeType, ....

not automatically via a kFieldPopUp.

 

But this is how we fill the pull down dynamicly:

void IProviderShapePane::Update( IWidgetsProvider* widgetProvider )
{
	SWidgetDefinition*	pSizeTypePU = widgetsProvider->GetWidgetByID( kWidgetID_SizeType);
	IWidgetDataPopup*	pPopupData = dynamic_cast<IWidgetDataPopup*>(pSizeTypePU->fpWidgetData);
	pPopupData->Clear();
	std::vector<TXString> listOptions = this->GetListOptions();
	for ( size_t i = 0; i < list_sets.size(); i++ )
		pDataSetPU->Add( TXString::ToStringInt( i + 1 ), listOptions[i] );
}

 

Off course, this is not dimming or disabling, but it might work too for you?

I did some quick experimenting to see if doing something like placing an underscore in front of the display name would lock the choice the way it does with a parameter, and don't see any difference.

 

I thin this would be a worthy enhancement. I recently had a user confused why a pull-down item disabled other widgets. In theory, the pull-down item itself should have been disabled.

Thanks for the replies! But recreating the entire widget does not seem to be a reasonable solution. There really needs to be an SDK call or member function of the widget for that.
