- This window is a text widget. It displays one or more lines of text
- and allows you to edit the text. Here is a summary of the things you
- can do to a text widget:
-
- 1. Scrolling. Use the scrollbar to adjust the view in the text window.
-
- 2. Scanning. Press mouse button 2 in the text window and drag up or down.
- This will drag the text at high speed to allow you to scan its contents.
-
- 3. Insert text. Press mouse button 1 to set the insertion cursor, then
- type text. What you type will be added to the widget. You can backspace
- over what you've typed using either the backspace key, the delete key,
- or Control+h.
-
- 4. Select. Press mouse button 1 and drag to select a range of characters.
- Once you've released the button, you can adjust the selection by pressing
- button 1 with the shift key down. This will reset the end of the
- selection nearest the mouse cursor and you can drag that end of the
- selection by dragging the mouse before releasing the mouse button.
- You can double-click to select whole words, or triple-click to select
- whole lines.
-
- 5. Delete. To delete text, select the characters you'd like to delete
- and type Control+d.
-
- 6. Copy the selection. To copy the selection either from this window
- or from any other window or application, select what you want, click
- button 1 to set the insertion cursor, then type Control+v to copy the
- selection to the point of the insertion cursor.
-
- 7. Resize the window. This widget has been configured with the "setGrid"
- option on, so that if you resize the window it will always resize to an
- even number of characters high and wide. Also, if you make the window
- narrow you can see that long lines automatically wrap around onto
- additional lines so that all the information is always visible.
-
- When you're finished with this demonstration, press the "OK" button
- below.}
