Detailed Description

A container which arranges its child widgets in rows and columns.

It is very similar to Box, but it consistently uses Widget's margin and expand properties instead of custom child properties, and it fully supports height-for-width geometry management.

Children are added using attach(). They can span multiple rows or columns. It is also possible to add a child next to an existing child, using attach_next_to(). To remove a child from the grid, use remove(). The behaviour of Grid when several children occupy the same grid cell is undefined.

Since gtkmm 3.0:

Member Function Documentation

◆ attach()

void Gtk::Grid::attach ( Widget child,
int  column,
int  row,
int  width = 1,
int  height = 1 
)

Adds a widget to the grid.

The position of child is determined by column and row. The number of “cells” that child will occupy is determined by width and height.

Parameters
childThe widget to add.
columnThe column number to attach the left side of child to.
rowThe row number to attach the top side of child to.
widthThe number of columns that child will span.
heightThe number of rows that child will span.

◆ attach_next_to() [1/2]

void Gtk::Grid::attach_next_to ( Widget child,
PositionType  side,
int  width = 1,
int  height = 1 
)

A attach_next_to() convenience overload.

◆ attach_next_to() [2/2]

void Gtk::Grid::attach_next_to ( Widget child,
Widget sibling,
PositionType  side,
int  width = 1,
int  height = 1 
)

Adds a widget to the grid.

The widget is placed next to sibling, on the side determined by side. The attach_next_to() without the sibling parameter places the widget in row 0 (for left or right placement) or column 0 (for top or bottom placement), at the end indicated by side.

Attaching widgets labeled [1], [2], [3] without the sibling parameter and side == Gtk::PositionType::LEFT yields a layout of [3][2][1].

Parameters
childThe widget to add.
siblingThe child of grid that child will be placed next to, or omitted to place child at the beginning or end.
sideThe side of sibling that child is positioned next to.
widthThe number of columns that child will span.
heightThe number of rows that child will span.

Children which are attached at or to the right of this position are moved one column to the right. Children which span across this position are grown to span the new column.

Parameters
positionThe position to insert the column at.

◆ insert_next_to()

void Gtk::Grid::insert_next_to ( Widget sibling,
PositionType  side 
)

Inserts a row or column at the specified position.

The new row or column is placed next to sibling, on the side determined by side. If side is Gtk::PositionType::TOP or Gtk::PositionType::BOTTOM, a row is inserted. If side is Gtk::PositionType::LEFT of Gtk::PositionType::RIGHT, a column is inserted.

Parameters
siblingThe child of grid that the new row or column will be placed next to.
sideThe side of sibling that child is positioned next to.

◆ insert_row()

void Gtk::Grid::insert_row ( int  position)

Inserts a row at the specified position.
