Description

GtkTooltip belongs to the new tooltips API that was introduced in GTK+ 2.12 and which deprecates the old GtkTooltips API.

Basic tooltips can be realized simply by using gtk_widget_set_tooltip_text() or gtk_widget_set_tooltip_markup() without any explicit tooltip object. For fancy tooltips, you will likely connect to the "query-tooltip" signal, which is passed a GtkTooltip object as the last parameter. You can use functions like gtk_tooltip_set_icon() to modify the tooltip.

typedef struct _GtkTooltip GtkTooltip;

gtk_tooltip_set_markup ()

void                gtk_tooltip_set_markup              (GtkTooltip *tooltip,
                                                         const gchar *markup);

Sets the text of the tooltip to be markup, which is marked up with the Pango text markup language. If markup is NULL, the label will be hidden.

`tooltip` :	a GtkTooltip
`markup` :	a markup string (see Pango markup format) or `NULL`

Since 2.12

gtk_tooltip_set_text ()

void                gtk_tooltip_set_text                (GtkTooltip *tooltip,
                                                         const gchar *text);

Sets the text of the tooltip to be text. If text is NULL, the label will be hidden. See also gtk_tooltip_set_markup().

`tooltip` :	a GtkTooltip
`text` :	a text string or `NULL`

Since 2.12

gtk_tooltip_set_icon ()

void                gtk_tooltip_set_icon                (GtkTooltip *tooltip,
                                                         GdkPixbuf *pixbuf);

Sets the icon of the tooltip (which is in front of the text) to be pixbuf. If pixbuf is NULL, the image will be hidden.

`tooltip` :	a GtkTooltip
`pixbuf` :	a GdkPixbuf, or `NULL`

Since 2.12

gtk_tooltip_set_icon_from_stock ()

void                gtk_tooltip_set_icon_from_stock     (GtkTooltip *tooltip,
                                                         const gchar *stock_id,
                                                         GtkIconSize size);

Sets the icon of the tooltip (which is in front of the text) to be the stock item indicated by stock_id with the size indicated by size. If stock_id is NULL, the image will be hidden.

`tooltip` :	a GtkTooltip
`stock_id` :	a stock icon name, or `NULL`
`size` :	a stock icon size

Since 2.12

gtk_tooltip_set_custom ()

void                gtk_tooltip_set_custom              (GtkTooltip *tooltip,
                                                         GtkWidget *custom_widget);

Replaces the widget packed into the tooltip with custom_widget. By default a box with a GtkImage and GtkLabel is embedded in the tooltip, which can be configured using gtk_tooltip_set_markup() and gtk_tooltip_set_icon().

`tooltip` :	a GtkTooltip
`custom_widget` :	a GtkWidget

Since 2.12

gtk_tooltip_trigger_tooltip_query ()

void                gtk_tooltip_trigger_tooltip_query   (GdkDisplay *display);

Triggers a new tooltip query on display, in order to update the current visible tooltip, or to show/hide the current tooltip. This function is useful to call when, for example, the state of the widget changed by a key press.

display : a GtkDisplay
