Struct gtk4::ShortcutsSection [−][src]
pub struct ShortcutsSection(_);Expand description
A ShortcutsSection collects all the keyboard shortcuts and gestures
for a major application mode.
If your application needs multiple sections, you should give each
section a unique property::ShortcutsSection::section-name and
a property::ShortcutsSection::title that can be shown in the
section selector of the ShortcutsWindow.
The property::ShortcutsSection::max-height property can be used
to influence how the groups in the section are distributed over pages
and columns.
This widget is only meant to be used with ShortcutsWindow.

Implementations
Creates a new builder-pattern struct instance to construct ShortcutsSection objects.
This method returns an instance of ShortcutsSectionBuilder which can be used to create ShortcutsSection objects.
The maximum number of lines to allow per column.
This property can be used to influence how the groups in this section are distributed across pages and columns. The default value of 15 should work in most cases.

A unique name to identify this section among the sections
added to the ShortcutsWindow.
Setting the property::ShortcutsWindow::section-name property
to this string will make this section shown in the ShortcutsWindow.

Setting the property::ShortcutsWindow::section-name property
to this string will make this section shown in the ShortcutsWindow.
The string to show in the section selector of the ShortcutsWindow
for this section.
If there is only one section, you don’t need to set a title, since the section selector will not be shown in this case.
The string to show in the section selector of the ShortcutsWindow
for this section.
If there is only one section, you don’t need to set a title, since the section selector will not be shown in this case.
A view name to filter the groups in this section by.
See property::ShortcutsGroup::view.
Applications are expected to use the
property::ShortcutsWindow::view-name property
for this purpose.

Tries to cast to an object of type T. This handles upcasting, downcasting
and casting between interface and interface implementors. All checks are performed at
runtime, while downcast and upcast will do many checks at compile-time already. Read more
