|
|
*
|
|
* Let me introduce to the wonderful world of X terminals and their handling of
|
|
* mouse wheel now. First, one sad fact: reasonable mouse wheel reporting
|
|
* support has only xterm itself (from everything I tried) - it is relatively
|
|
* elegant, it shouldn't confuse existing applications too much and it is
|
|
* generally non-conflicting with the old behaviour.
|
|
*
|
|
* All other terminals are doing absolutely terrible things, making it hell on
|
|
* the hearth to support mouse wheels. rxvt will send the buttons as succeeding
|
|
* button numbers (3, 4) in normal sequences, but that has a little problem -
|
|
* button 3 is also alias for button release; welcome to the wonderful world of
|
|
* X11. But at least, rxvt will send only "press" sequence, but no release
|
|
* sequence (it really doesn't make sense for wheels anyway, does it?). That
|
|
* has the advantage that you can do some heuristic (see below) to at least
|
|
* partially pace with this terrible thing.
|
|
*
|
|
* But now, let's see another nice pair of wonderful terminals: aterm and
|
|
* Eterm. They emit same braindead sequence for wheel up/down as rxvt, but
|
|
* that's not all. Yes, you guessed it - they send even the release sequence
|
|
* (immediatelly after press sequence) for the wheels. So, you will see
|
|
* something like:
|
|
*
|
|
* old glasses - <button1 press> <release> <release> <release>
|
|
* new glasses - <button1 press> <wheelup press> <wheelup press> <wheelup press>
|
|
* smartglasses1-<button1 press> <release> <wheelup press> <wheelup press>
|
|
* smartglasses2-<button1 press> <release> <wheelup press> <release>
|
|
*
|
|
* But with smartglasses2, you will have a problem with rxvt when someone will
|
|
* move the wheel multiple times - only half of the times it will be recorded.
|
|
* Poof. No luck :-(.
|
|
*
|
|
* [smartglasses1]:
|
|
* When user presses some button and then moves the wheel, action for button
|
|
* release will be done and when he will release the button, action for the
|
|
* wheel will be done. That's unfortunately inevitable in order to work under
|
|
* rxvt :-(.
