placeHolder()

QWidget * GUI::Util::Layout::placeHolder

(

)

Returns empty widget to occupy place in layout.

Definition at line 121 of file LayoutUtils.cpp.

{
    auto* result = new QWidget;
    result->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding);
    return result;
}

removeColumn()

void GUI::Util::Layout::removeColumn	(	QGridLayout *	layout,
		int	column,
		bool	deleteWidgets = true
	)

Removes column from grid layout.

Removes all layout items on the given column from the given grid layout. If deleteWidgets is true, all concerned child widgets become not only removed from the layout, but also deleted. Note that this function doesn't actually remove the column itself from the grid layout, as this isn't possible (i.e. the columnCount() and column indices will stay the same after this function has been called).

Definition at line 108 of file LayoutUtils.cpp.

{
    remove(layout, -1, column, deleteWidgets);
    layout->setColumnMinimumWidth(column, 0);
    layout->setColumnStretch(column, 0);
}

removeRow()

void GUI::Util::Layout::removeRow	(	QGridLayout *	layout,
		int	row,
		bool	deleteWidgets = true
	)

Removes row from grid layout (important: doesn't change row count).

Removes all layout items on the given row from the given grid layout. If deleteWidgets is true, all concerned child widgets become not only removed from the layout, but also deleted. Note that this function doesn't actually remove the row itself from the grid layout, as this isn't possible (i.e. the rowCount() and row indices will stay the same after this function has been called).

Definition at line 92 of file LayoutUtils.cpp.

{
    remove(layout, row, -1, deleteWidgets);
    layout->setRowMinimumHeight(row, 0);
    layout->setRowStretch(row, 0);
}
