Struct gtk4::GridLayout

source ·
#[repr(transparent)]
pub struct GridLayout { /* private fields */ }
Expand description

GridLayout is a layout manager which arranges child widgets in rows and columns.

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 GridLayoutChild associated to each child widget.

The behaviour of GridLayout when several children occupy the same grid cell is undefined.

GridLayout can be used like a 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 BoxLayout.

Implementations§

Creates a new GridLayout.

Returns

the newly created GridLayout

Creates a new builder-pattern struct instance to construct GridLayout objects.

This method returns an instance of GridLayoutBuilder which can be used to create GridLayout objects.

Retrieves the row set with gtk_grid_layout_set_baseline_row().

Returns

the global baseline row

Checks whether all columns of @self should have the same width.

Returns

true if the columns are homogeneous, and false otherwise

Retrieves the spacing set with gtk_grid_layout_set_column_spacing().

Returns

the spacing between consecutive columns

Returns the baseline position of @row.

If no value has been set with set_row_baseline_position(), the default value of BaselinePosition::Center is returned.

row

a row index

Returns

the baseline position of @row

Checks whether all rows of @self should have the same height.

Returns

true if the rows are homogeneous, and false otherwise

Retrieves the spacing set with gtk_grid_layout_set_row_spacing().

Returns

the spacing between consecutive rows

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 @self.

row

the row index

Sets whether all columns of @self should have the same width.

homogeneous

true to make columns homogeneous

Sets the amount of space to insert between consecutive columns.

spacing

the amount of space between columns, in pixels

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

row

a row index

pos

a BaselinePosition

Sets whether all rows of @self should have the same height.

homogeneous

true to make rows homogeneous

Sets the amount of space to insert between consecutive rows.

spacing

the amount of space between rows, in pixels
