Add tips to your widgets.
Basic tooltips can be realized simply by using set_tooltip_text() or set_tooltip_markup() without any explicit tooltip object.
When you need a tooltip with a little more fancy contents, like adding an image, or you want the tooltip to have different contents per Gtk::TreeView row or cell, you will have to do a little more work:
Return true from your query-tooltip handler. This causes the tooltip to be show. If you return false, it will not be shown.

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.
| GtkTooltip* Gtk::Tooltip::gobj_copy | ( | ) |
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
| void Gtk::Tooltip::set_custom | ( | Widget & | custom_widget | ) |
Replaces the widget packed into the tooltip with custom_widget.
custom_widget does not get destroyed when the tooltip goes away. By default a box with a Gtk::Image and Gtk::Label is embedded in the tooltip, which can be configured using set_markup() and set_icon().
| custom_widget | A Gtk::Widget, or nullptr to unset the old custom widget. |
| void Gtk::Tooltip::set_icon | ( | const Glib::RefPtr< Gdk::Paintable > & | paintable | ) |
Sets the icon of the tooltip (which is in front of the text) to be paintable.
If paintable is nullptr, the image will be hidden.
| paintable | A Gdk::Paintable. |
| void Gtk::Tooltip::set_icon | ( | const Glib::RefPtr< Gio::Icon > & | gicon | ) |
Sets the icon of the tooltip (which is in front of the text) to be the icon indicated by gicon with the size indicated by size.
If gicon is nullptr, the image will be hidden.
| gicon | A Gio::Icon representing the icon. |
| void Gtk::Tooltip::set_icon | ( | const Glib::ustring & | icon_name | ) |
Sets the icon of the tooltip (which is in front of the text) to be the icon indicated by icon_name with the size indicated by size.
If icon_name is nullptr, the image will be hidden.
| icon_name | An icon name. |
| void Gtk::Tooltip::set_markup | ( | const Glib::ustring & | markup | ) |
| void Gtk::Tooltip::set_text | ( | const Glib::ustring & | text | ) |
Sets the text of the tooltip to be text.
If text is nullptr, the label will be hidden. See also set_markup().
| text | A text string. |
| void Gtk::Tooltip::set_tip_area | ( | const Gdk::Rectangle & | rect | ) |
Sets the area of the widget, where the contents of this tooltip apply, to be rect (in widget coordinates).
This is especially useful for properly setting tooltips on Gtk::TreeView rows and cells, Gtk::IconViews, etc.
For setting tooltips on Gtk::TreeView, please refer to the convenience functions for this: Gtk::TreeView::set_tooltip_row() and Gtk::TreeView::set_tooltip_cell().
| rect | A Gdk::Rectangle. |
| void Gtk::Tooltip::unset_custom | ( | ) |
Remove the custom widget.
| void Gtk::Tooltip::unset_icon | ( | ) |
Hide the image.
| void Gtk::Tooltip::unset_markup | ( | ) |
Hide the label.
| void Gtk::Tooltip::unset_text | ( | ) |
Hide the label.
