The Linux-SRT user interface includes window manager integration. Currently this only supports Afterstep, but it should be relatively easy to port to anything else.
Modified configuration option (look)
The first change is a general purpose way of defining multiple different images for each button position on your titlebar. These images can be changed by afterstep in response to various conditions affecting the window, such as its scheduling status or whether it is maximized.
TitleButton <state * 10 + button> <pixmap>
[0..9] [0..9]
Buttons are numbered in the usual Afterstep way, and states are indicated
by adding multiples of 10. For example, button number 1 is the one
on the far left in its default state, button number 32 is the one
on the far right in its third alternate state.
New configuration option (feel)
ButtonFeedback <button> <category>
[0..9]
This is what you use to indicate that a particular button
should change state to provide feedback of a particular kind.
Feedback categories:
0 = None
1 = Scheduling
2 = Maximisation
3 = Shading
4 = Stickyness
All categories return a boolean state except for scheduling.
States for the scheduling feedback category:
0 = normal
1 = QOS
2 = FIFO/RR
3 = -ve nice
4 = +ve nice,
5 = IDLE
6 = PAUSE
New built-in function
SetButtonState <button> <state>
[0..9] [0..9]
Not terribly useful, except for modules or complex Afterstep
functions perhaps. Provided for completeness.
Example look file extract
# TitleButtons: # [1] [3] [5] [7] [9] (title) [0] [8] [6] [4] [2] TitleButton 01 cross-tb.xpm cross-tp.xpm TitleButton 03 circ-tb.xpm circ-tp.xpm TitleButton 13 checks-tb.xpm checks-tp.xpm TitleButton 23 red-tb.xpm red-tp.xpm TitleButton 33 red-tb.xpm red-tp.xpm TitleButton 43 green-tb.xpm green-tp.xpm TitleButton 53 green-tb.xpm green-tp.xpm TitleButton 63 pause-tb.xpm pause-tp.xpm TitleButton 05 rivets-tb.xpm rivets-tp.xpm TitleButton 15 stripe-tb.xpm stripe-tp.xpm TitleButton 08 dot-tb.xpm dot-tp.xpm TitleButton 06 horiz-tb.xpm horiz-tp.xpm TitleButton 16 blinds-tb.xpm blinds-tp.xpm TitleButton 04 vert-tb.xpm vert-tp.xpm TitleButton 14 downup2-tb.xpm downup2-tp.xpm TitleButton 02 resize-tb.xpm resize-tp.xpm
This corresponds to the following colours:
| Black | - standard scheduling (OTHER with nice = 0) |
| Blue | - primary policy is QOS |
| Red | - primary policy is FIFO / RR, or OTHER with nice < 0 |
| Green | - primary policy is IDLE, or OTHER with nice > 0 |
| Pause symbol | - primary policy is PAUSE |
Example feel file extract
# Btn Pos Mods Action # Buttons on left side (1,3,5,7,9): Mouse 1 1 A Delete Mouse 2 1 A Destroy Mouse 1 3 A Exec "" setp -t -l a <pid> Mouse 1 3 S Exec "" setp -t -f 25 a <pid> Mouse 2 3 A Exec "" setp -t -r idle a <pid> Mouse 2 3 S Exec "" setp -t -n 19 a <pid> Mouse 3 3 A Exec "" setp -t -r pause a <pid> Mouse 1 5 A Stick ButtonFeedback 3 1 ButtonFeedback 5 4 ButtonFeedback 6 3 ButtonFeedback 4 2 # Buttons on right side (10,8,6,4,2): Mouse 1 8 A Iconify Mouse 1 6 A Shade Mouse 1 4 A Maximize 0 92 Mouse 2 4 A Maximize 100 92 Mouse 3 4 A Maximize 100 0 Mouse 1 2 A Resize
This defines the following bindings for mouse clicks on button number 3:
If the current parameters are non-standard, any button press reverts the policy to SCHED_OTHER, nice 0 (we are using setp -t). Otherwise,
| LMB | = | Join the reserve specified by /etc/qosrc |
| Shift-LMB | = | FIFO, priority 25 |
| MMB | = | IDLE |
| Shift-MMB | = | Nice 19 |
| RMB | = | PAUSE |
