输入小部件是单行文本输入小部件。如果输入的文本长于窗口小部件的分配，窗口小部件将滚动以使光标位置可见。
可以使用此类的set_visibility()方法以密码模式转换输入字段。输入的文本替换为invisible_char()方法选择的字符，默认为’*’。
Entry类具有以下构造函数-
gtk.Entry(max = 0)
在此，max表示字符中输入字段的最大长度。该参数采用数值(0-65536)。
下表显示了Entry类的重要方法-
| S.NO | Methods and Description |
|---|---|
| 1 |
set_visibility(visible) If false, the contents are obscured by replacing the characters with the default invisible character — ‘*’ |
| 2 |
set_invisible_char(char) The default ‘*’ characters in the entry field are replaced by char |
| 3 |
set_max_length(x) This sets the “max-length” property to the value of x. (0-65536) |
| 4 |
set_text(str) This sets the “text” property to the value of str. The string in str replaces the current contents of the entry. |
| 5 |
get_text() This returns the value of the “text” property which is a string containing the contents of the entry. |
| 6 |
set_alignment() This sets the “xalign” property to the value of xalign. set_alignment() controls the horizontal positioning of the contents in the Entry field. |
条目小部件发出以下信号-
| activate | This is emitted when the entry is activated either by user action or programmatically with the gtk.Widget.activate() method. |
| backspace | This is emitted when the Backspace key is entered from the keyboard. |
| copy-clipboard | This is emitted when the selection text in the entry is copied to the clipboard. |
| cut-clipboard | This is emitted when the selection in the entry is cut and placed in the clipboard. |
| paste-clipboard | This is emitted when the contents of the clipboard are pasted into the entry. |
