[]Struct gtk::Button

pub struct Button(_, _);

The Button widget is generally used to trigger a callback function that is called when the button is pressed. The various signals and how to use them are outlined below.

The Button widget can hold any valid child widget. That is, it can hold almost any other standard Widget. The most commonly used child is the Label.

CSS nodes

Button has a single CSS node with name button. The node will get the style classes .image-button or .text-button, if the content is just an image or label, respectively. It may also receive the .flat style class.

Other style classes that are commonly used with Button include .suggested-action and .destructive-action. In special cases, buttons can be made round by adding the .circular style class.

Button-like widgets like ToggleButton, MenuButton, VolumeButton, LockButton, ColorButton, FontButton or FileChooserButton use style classes such as .toggle, .popup, .scale, .lock, .color, .font, .file to differentiate themselves from a plain Button.

Methods

impl Button[src]

pub fn new() -> Button[src]

Creates a new Button widget. To add a child widget to the button, use ContainerExt::add.

Returns

The newly created Button widget.

pub fn new_from_icon_name(icon_name: Option<&str>, size: IconSize) -> Button[src]

Creates a new button containing an icon from the current icon theme.

If the icon name isn’t known, a “broken image” icon will be displayed instead. If the current icon theme is changed, the icon will be updated appropriately.

This function is a convenience wrapper around Button::new and ButtonExt::set_image.

icon_name

an icon name or None

size

an icon size (IconSize)

Returns

a new Button displaying the themed icon

pub fn new_with_label(label: &str) -> Button[src]

Creates a Button widget with a Label child containing the given text.

label

The text you want the Label to hold.

Returns

The newly created Button widget.

pub fn new_with_mnemonic(label: &str) -> Button[src]

Creates a new Button containing a label. If characters in label are preceded by an underscore, they are underlined. If you need a literal underscore character in a label, use “__” (two underscores). The first underlined character represents a keyboard accelerator called a mnemonic. Pressing Alt and that key activates the button.

label

The text of the button, with an underscore in front of the mnemonic character

Returns

a new Button
