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.

Gtk::Grid::Grid | ( | ) |
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.
child | The widget to add. |
column | The column number to attach the left side of child to. |
row | The row number to attach the top side of child to. |
width | The number of columns that child will span. |
height | The number of rows that child will span. |
void Gtk::Grid::attach_next_to | ( | Widget & | child, |
PositionType | side, | ||
int | width = 1 , |
||
int | height = 1 |
||
) |
A attach_next_to() convenience overload.
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].
child | The widget to add. |
sibling | The child of grid that child will be placed next to, or omitted to place child at the beginning or end. |
side | The side of sibling that child is positioned next to. |
width | The number of columns that child will span. |
height | The number of rows that child will span. |
int Gtk::Grid::get_baseline_row | ( | ) | const |
Returns which row defines the global baseline of grid.
Widget * Gtk::Grid::get_child_at | ( | int | column, |
int | row | ||
) |
Gets the child of grid whose area covers the grid cell at column, row.
column | The left edge of the cell. |
row | The top edge of the cell. |
Gets the child of grid whose area covers the grid cell at column, row.
column | The left edge of the cell. |
row | The top edge of the cell. |
bool Gtk::Grid::get_column_homogeneous | ( | ) | const |
Returns whether all columns of grid have the same width.
guint Gtk::Grid::get_column_spacing | ( | ) | const |
Returns the amount of space between the columns of grid.
BaselinePosition Gtk::Grid::get_row_baseline_position | ( | int | row | ) | const |
Returns the baseline position of row.
See set_row_baseline_position().
row | A row index. |
bool Gtk::Grid::get_row_homogeneous | ( | ) | const |
Returns whether all rows of grid have the same height.
guint Gtk::Grid::get_row_spacing | ( | ) | const |
Returns the amount of space between the rows of grid.

void Gtk::Grid::insert_column | ( | int | position | ) |
Inserts a column at the specified position.
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.
position | The position to insert the column at. |
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.
sibling | The child of grid that the new row or column will be placed next to. |
side | The side of sibling that child is positioned next to. |
void Gtk::Grid::insert_row | ( | int | position | ) |
Inserts a row at the specified position.
Children which are attached at or below this position are moved one row down. Children which span across this position are grown to span the new row.
position | The position to insert the row at. |
