标签窗口小部件可用于显示不可编辑的文本。标签在内部被许多其他小部件使用。例如，Button有一个标签可以在脸上显示文本。同样，MenuItem对象也具有标签。标签是无窗口对象，因此它不能直接接收事件。
Label类具有一个简单的构造函数-
gtk.Label(str = None)
以下有用的方法可以与Label对象一起使用-
| S.NO | Methods and Description |
|---|---|
| 1 |
set_text() This sets new text as label |
| 2 |
get_text() This returns text from label |
| 3 |
set_use_underline() If true, an underscore in the text indicates the next character should be used for the mnemonic accelerator key. |
| 4 |
set_justify This sets the alignment of the lines in the text of the label relative to each other. Possible values are – gtk.JUSTIFY_LEFT, gtk.JUSTIFY_RIGHT, gtk.JUSTIFY_CENTER, and gtk.JUSTIFY_FILL. |
| 5 |
Set_line_wrap() If true, the line will be wrapped |
| 6 |
set_selectable() If true, the text in the label can be selected for copy-paste |
| 7 |
set_width_chars() This sets the width of a label |
标签小部件发出以下信号-
| activate-current-link | This gets emitted when the user activates a link in the label. |
| activate-link | This gets emitted to activate a URI. |
| copy-clipboard | This gets emitted when text is copied from the label to the clipboard. |
