* Simple X interface to the cut buffers in an X server. |
7 |
|
|
* The program creates a window subdivided into a number of subwindows, |
8 |
|
|
* one per cut buffer. The user may copy cut buffer contents around |
9 |
|
|
* using mouse buttons 1 and 2, or rotate the buffers using mouse |
10 |
|
|
* button 3. Buffers may be cleared by using Shift-button 2. |
11 |
|
|
* |
12 |
|
|
* Note that this program assumes the cut buffers contain textual |
13 |
|
|
* information, and displays buffer contents using the XDrawString |
14 |
|
|
* function. It is not suitable for use in any other environment. |
