Member Function Documentation

◆ init() [1/2]

bool qdesigner_internal::ResetPropertyCommand::init ( const QObjectList & list,
const QString & propertyName,
QObject * referenceObject = nullptr )

Definition at line 1313 of file qdesigner_propertycommand.cpp.

◆ init() [2/2]

bool qdesigner_internal::ResetPropertyCommand::init ( QObject * object,
const QString & propertyName )

Definition at line 1301 of file qdesigner_propertycommand.cpp.

◆ mergeWith()

bool qdesigner_internal::ResetPropertyCommand::mergeWith ( const QUndoCommand * command)
inlineoverrideprotectedvirtual

Attempts to merge this command with command.

Returns true on success; otherwise returns false.

If this function returns true, calling this command's redo() must have the same effect as redoing both this command and command. Similarly, calling this command's undo() must have the same effect as undoing command and this command.

QUndoStack will only try to merge two commands if they have the same id, and the id is not -1.

The default implementation returns false.

bool AppendText::mergeWith(const QUndoCommand *other)
{
if (other->id() != id()) // make sure other is also an AppendText command
return false;
m_text += static_cast<const AppendText*>(other)->m_text;
return true;
}

id(), QUndoStack::push()

Reimplemented from QUndoCommand.

◆ redo()

void qdesigner_internal::ResetPropertyCommand::redo ( )
overridevirtual

Applies a change to the document.

This function must be implemented in the derived class. Calling QUndoStack::push(), QUndoStack::undo() or QUndoStack::redo() from this function leads to undefined beahavior.

The default implementation calls redo() on all child commands.

undo()

Reimplemented from qdesigner_internal::QDesignerFormWindowCommand.
