Member Function Documentation
|
static |
Gets the singleton Gdk::DisplayManager object.
When called for the first time, this function consults the GDK_BACKEND environment variable to find out which of the supported GDK backends to use (in case GDK has been compiled with multiple backends). Applications can use gdk_set_allowed_backends() to limit what backends can be used.
- Returns
- The global Gdk::DisplayManager singleton.
| Glib::RefPtr<Display> Gdk::DisplayManager::get_default_display | ( | ) |
Gets the default Gdk::Display.
- Returns
- A Gdk::Display, or
nullptrif there is no default display.
| Glib::RefPtr<const Display> Gdk::DisplayManager::get_default_display | ( | ) | const |
Gets the default Gdk::Display.
- Returns
- A Gdk::Display, or
nullptrif there is no default display.
|
static |
Get the GType for this class, for use with the underlying GObject type system.
|
inline |
Provides access to the underlying C GObject.
|
inline |
Provides access to the underlying C GObject.
| GdkDisplayManager* Gdk::DisplayManager::gobj_copy | ( | ) |
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
| std::vector< Glib::RefPtr<Display> > Gdk::DisplayManager::list_displays | ( | ) |
List all currently open displays.
- Returns
- A vector of Gdk::Display objects.
| Glib::RefPtr<Display> Gdk::DisplayManager::open_display | ( | const Glib::ustring & | name | ) |
Opens a display.
- Parameters
-
name The name of the display to open.
- Returns
- A Gdk::Display, or
nullptrif the display could not be opened.
|
noexcept |
| Glib::PropertyProxy< Glib::RefPtr<Display> > Gdk::DisplayManager::property_default_display | ( | ) |
The default display for GDK.
- Returns
- A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.
| Glib::PropertyProxy_ReadOnly< Glib::RefPtr<Display> > Gdk::DisplayManager::property_default_display | ( | ) | const |
The default display for GDK.
- Returns
- A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.
| void Gdk::DisplayManager::set_default_display | ( | const Glib::RefPtr< Display >& | display | ) |
Sets display as the default display.
- Parameters
-
display A Gdk::Display.
| Glib::SignalProxy<void(const Glib::RefPtr<Display>&)> Gdk::DisplayManager::signal_display_opened | ( | ) |
- Slot Prototype:
void on_my_display_opened(const Glib::RefPtr<Display>& display)
Flags: Run Last
The signal_display_opened() signal is emitted when a display is opened.
- Parameters
-
display The opened display.

- Parameters
-
object The C instance. take_copy False if the result should take ownership of the C instance. True if it should take a new copy or ref.
- Returns
