Detailed Description

Layout manager for grid-like widgets.

Gtk::GridLayout is a layout manager which arranges child widgets in rows and columns, with arbitrary positions and horizontal/vertical spans.

Children have an "attach point" defined by the horizontal and vertical index of the cell they occupy; children can span multiple rows or columns. The layout properties for setting the attach points and spans are set using the Gtk::GridLayoutChild associated to each child widget.

The behaviour of Gtk::Grid when several children occupy the same grid cell is undefined.

Gtk::GridLayout can be used like a Gtk::BoxLayout if all children are attached to the same row or column; however, if you only ever need a single row or column, you should consider using Gtk::BoxLayout.

Since gtkmm 3.96:

void Gtk::GridLayout::set_baseline_row ( int row )

Sets which row defines the global baseline for the entire grid.

Each row in the grid can have its own local baseline, but only one of those is global, meaning it will be the baseline in the parent of the grid.

Parameters

row	The row index.

void Gtk::GridLayout::set_column_homogeneous ( bool homogeneous = true )

Sets whether all columns of grid should have the same width.

Parameters

homogeneous true to make columns homogeneous.

void Gtk::GridLayout::set_column_spacing ( guint spacing )

Sets the amount of space to insert between consecutive columns.

Parameters

spacing The amount of space between columns, in pixels.

void Gtk::GridLayout::set_row_baseline_position	(	int	row,
		BaselinePosition	pos
	)

Sets how the baseline should be positioned on row of the grid, in case that row is assigned more space than is requested.

Parameters

row	A row index.
pos	A Gtk::BaselinePosition.

void Gtk::GridLayout::set_row_homogeneous ( bool homogeneous = true )

Sets whether all rows of grid should have the same height.

Parameters

homogeneous true to make rows homogeneous.

void Gtk::GridLayout::set_row_spacing ( guint spacing )

Sets the amount of space to insert between consecutive rows.

Parameters

spacing The amount of space between rows, in pixels.
