## Detailed Description

Event capturing box.

This widget adds an X Window where one does not normally appear, allowing you to capture events. It will receive any event which is specified with set_events().

This widget is generally used to add Gtk::Tooltip, button presses, and clipping to widgets derived from Gtk::Misc.

Gtk::EventBox::EventBox | ( |  | ) |

## Member Function Documentation

bool Gtk::EventBox::get_above_child | ( |  | ) | const

Returns whether the event box window is above or below the windows of its child.

See set_above_child() for details.

Since gtkmm 2.4:

Returns
  `true` if the event box window is above the window of its child.

static GType Gtk::EventBox::get_type | ( |  | ) |

static

Get the GType for this class, for use with the underlying GObject type system.

bool Gtk::EventBox::get_visible_window | ( |  | ) | const

Returns whether the event box has a visible window.

See set_visible_window() for details.

Since gtkmm 2.4:

Returns
  `true` if the event box window is visible.

GtkEventBox* Gtk::EventBox::gobj | ( |  | ) |

inline

Provides access to the underlying C GtkObject.

const GtkEventBox* Gtk::EventBox::gobj | ( |  | ) | const

inline

Provides access to the underlying C GtkObject.

Glib::PropertyProxy< bool > Gtk::EventBox::property_above_child | ( |  | ) |

Whether the event-trapping window of the eventbox is above the window of the child widget as opposed to below it.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

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< bool > Gtk::EventBox::property_above_child | ( |  | ) | const

Whether the event-trapping window of the eventbox is above the window of the child widget as opposed to below it.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy< bool > Gtk::EventBox::property_visible_window | ( |  | ) |

Whether the event box is visible, as opposed to invisible and only used to trap events.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

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< bool > Gtk::EventBox::property_visible_window | ( |  | ) | const

Whether the event box is visible, as opposed to invisible and only used to trap events.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

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 Gtk::EventBox::set_above_child | ( | bool | above_child = `true` | ) |

Set whether the event box window is positioned above the windows of its child, as opposed to below it.

If the window is above, all events inside the event box will go to the event box. If the window is below, events in windows of child widgets will first got to that widget, and then to its parents.

The default is to keep the window below the child.

Since gtkmm 2.4:

Parameters

  above_child | `true` if the event box window is above its child.

void Gtk::EventBox::set_visible_window | ( | bool | visible_window = `true` | ) |

Set whether the event box uses a visible or invisible child window.

The default is to use visible windows.

In an invisible window event box, the window that the event box creates is a Gdk::INPUT_ONLY window, which means that it is invisible and only serves to receive events.

A visible window event box creates a visible (Gdk::INPUT_OUTPUT) window that acts as the parent window for all the widgets contained in the event box.

You should generally make your event box invisible if you just want to trap events. Creating a visible window may cause artifacts that are visible to the user, especially if the user is using a theme with gradients or pixmaps.

The main reason to create a non input-only event box is if you want to set the background to a different color or draw on it.

<note> There is one unexpected issue for an invisible event box that has its window below the child. (See set_above_child().) Since the input-only window is not an ancestor window of any windows that descendent widgets of the event box create, events on these windows aren't propagated up by the windowing system, but only by GTK+. The practical effect of this is if an event isn't in the event mask for the descendant window (see Gtk::Widget::add_events()), it won't be received by the event box.

This problem doesn't occur for visible event boxes, because in that case, the event box window is actually the ancestor of the descendant windows, not just at the same place on the screen. </note>

Since gtkmm 2.4:

Parameters

  visible_window | `true` to make the event box have a visible window.
