setNeedIndexConversion()

void KisResourceItemDelegate::setNeedIndexConversion

(

bool

value

)

When index conversion is set, the delegate will request only KisAbstractResourceModel::{Id,ResourceType,Name} from the local index and will use this info to resolve the index in the global resources model. It is necessary for, e.g. KisResourceItemListWidget in the bundle creator

Definition at line 31 of file KisResourceItemDelegate.cpp.

    m_isWidget = isWidget;
}

setShowText()

void KisResourceItemDelegate::setShowText

(

bool

showText

    m_showText = showText;
