Widget wrapper for binary (BLOB) fields.
Manages an editor widget Widget and wrapper share the same parent.
virtual QVariant value() const =0
Will be used to access the widget's value.
virtual void showIndeterminateState()
Sets the widget to display in an indeterminate "mixed value" state.
void setEnabled(bool enabled) override
Is used to enable or disable the edit functionality of the managed widget.
A bar for displaying non-blocking messages to the user.
Definition: qgsmessagebar.h:61
Represents a vector layer which manages a vector based data sets.
virtual bool valid() const =0
Returns true if the widget has been properly initialized.
virtual void initWidget(QWidget *editor)
This method should initialize the editor widget with runtime data.
virtual QWidget * createWidget(QWidget *parent)=0
This method should create a new widget with the provided parent.
