Member Function Documentation

bool SimShell::Gui::PTreeModel::IsOnlyEditData ( ) const

Test whether the "only edit data" option set.

"Only edit data" means the user cannot modify key names, delete, add, move subtrees. Default = false

Definition at line 221 of file PTreeModel.cpp.

bool SimShell::Gui::PTreeModel::MoveRow	(	int	old_row,
		QModelIndex const &	old_parent,
		int	new_row,
		QModelIndex const &	new_parent
	)

Moves a single row from one place to another.

Parameters

old_row	Index of row to move.
old_parent	Model index of parent of row to move.
new_row	New index for row.
new_parent	New parent for row.

Returns: true if successful.

Definition at line 245 of file PTreeModel.cpp.

Here is the call graph for this function:

bool SimShell::Gui::PTreeModel::MoveRows	(	int	old_row,
		QModelIndex const &	old_parent,
		int	new_row,
		QModelIndex const &	new_parent,
		int	count
	)

Moves a block of contagious rows from one place to another.

Parameters

old_row	Index of first row to move.
old_parent	Model index of parent of row to move.
new_row	New index for first row.
new_parent	New parent for row.
count	Number of rows to move.

Returns: true if successful.

Here is the caller graph for this function:

void SimShell::Gui::PTreeModel::SetOnlyEditData ( bool b )

Set the "only edit values" option.

See also: IsOnlyEditValues()

Definition at line 389 of file PTreeModel.cpp.

Referenced by SimShell::Gui::PTreeEditorWindow::OpenPath(), SimShell::Gui::PTreeEditorWindow::OpenPTree(), and SimShell::Gui::PTreeEditorWindow::SetOnlyEditData().

Here is the caller graph for this function:

void SimShell::Gui::PTreeModel::SetUndoStack ( QUndoStack * s )

Set this model to use a given undo stack.

All actions that change the model (e.g. insertRow(), setData()) will be pushed onto that stack.

Before using this model, it is necessary to call this method!
