Struct gtk4::Tooltip

#[repr(transparent)]
pub struct Tooltip { /* private fields */ }

Expand description

Tooltip is an object representing a widget tooltip.

Basic tooltips can be realized simply by using WidgetExt::set_tooltip_text() or WidgetExt::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 TreeView row or cell, you will have to do a little more work:

Set the property::Widget::has-tooltip property to true. This will make GTK monitor the widget for motion and related events which are needed to determine when and where to show a tooltip.
Connect to the signal::Widget::query-tooltip signal. This signal will be emitted when a tooltip is supposed to be shown. One of the arguments passed to the signal handler is a Tooltip object. This is the object that we are about to display as a tooltip, and can be manipulated in your callback using functions like set_icon(). There are functions for setting the tooltip’s markup, setting an image from a named icon, or even putting in a custom widget.
Return true from your ::query-tooltip handler. This causes the tooltip to be show. If you return false, it will not be shown.

Implementations

source

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 Image and Label is embedded in the tooltip, which can be configured using gtk_tooltip_set_markup() and gtk_tooltip_set_icon().

`custom_widget`

a Widget, or None to unset the old custom widget.

source

pub fn set_icon(&self, paintable: Option<&impl IsA<Paintable>>)

Sets the icon of the tooltip (which is in front of the text) to be @paintable. If @paintable is None, the image will be hidden.

`paintable`

a gdk::Paintable

source

pub fn set_icon_from_gicon(&self, gicon: Option<&impl IsA<Icon>>)

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 None, the image will be hidden.

`gicon`

a GIcon representing the icon

source

pub fn set_icon_from_icon_name(&self, icon_name: Option<&str>)

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 None, the image will be hidden.

`icon_name`

an icon name

source

pub fn set_markup(&self, markup: Option<&str>)

Sets the text of the tooltip to be @markup.

The string must be marked up with Pango markup. If @markup is None, the label will be hidden.

`markup`

a string with Pango markup or NLL

source

pub fn set_text(&self, text: Option<&str>)

Sets the text of the tooltip to be @text.

If @text is None, the label will be hidden. See also set_markup().

`text`

a text string

source

pub fn set_tip_area(&self, rect: &Rectangle)

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 TreeView rows and cells, GtkIconViews, etc.

For setting tooltips on TreeView, please refer to the convenience functions for this: gtk_tree_view_set_tooltip_row() and gtk_tree_view_set_tooltip_cell().

`rect`

a gdk::Rectangle
