Hi,
I have question on definition key binding. I have an RCP application
and in application two plugins 'poll.lsn.monitorvariable' and
'poll.lsn.recorddata'. I defined keys shortcuts CTRL+G in each plugin
this way:
Plugin 'poll.lsn.monitorvariable:
<command
categoryId="poll.lsn.monitorvariable.commands"
defaultHandler="poll.lsn.monitorvariable.actions.ChartPropertiesHandler"
id="poll.lsn.monitorvariable.command.chartproperties"
name="%poll.lsn.monitorvariable.command.chartproperties">
</command>
<key
commandId="poll.lsn.monitorvariable.command.chartproperties"
contextId="org.eclipse.ui.contexts.window"
schemeId="poll.lsn.scheme"
sequence="M1+G">
</key>
Plugin 'poll.lsn.recorddata':
<command
categoryId="poll.lsn.recorddata.commands"
defaultHandler="poll.lsn.recorddata.actions.ShowChartAndLogAnHandler"
id="poll.lsn.recorddata.command.showchartlogan"
name="%poll.lsn.recorddata.command.showchartlogan">
</command>
<key
commandId="poll.lsn.recorddata.command.showchartlogan"
contextId="org.eclipse.ui.contexts.window"
schemeId="poll.lsn.scheme"
sequence="M1+G">
</key>
After started my application occurred a conflict for CTRL+G:
!MESSAGE A conflict occurred for CTRL+G:
Binding(CTRL+G,
ParameterizedCommand(Command(poll.lsn.monitorvariable.command.chartproperties,Nastavení
grafu,
,
Category(poll.lsn.monitorvariable.commands,Sledování
proměnných,MonitorVariable commands,true),
poll.lsn.monitorvariable.actions.ChartPropertiesHandler,
,,true),null),
poll.lsn.scheme,
org.eclipse.ui.contexts.window,,,system)
Binding(CTRL+G,

dat,RecordData commands,true),
poll.lsn.recorddata.actions.ShowChartAndLogAnHandler,
,,true),null),
poll.lsn.scheme,
org.eclipse.ui.contexts.window,,,system)
Is it possible somehow to resolve this error or do I have in my
application a unique keys shortcuts (Ctrl+G only once)? I'd rather solve
it somehow, but I do not know how.
Thanks.
Martin

Note:
Plugins 'poll.lsn.monitorvariable' and 'poll.lsn.recorddata' are in
different perspectives.
It is possible to have the same keys shortcuts in a variety of perspectives?

Your collision is happening because you've bound the same key to different commands in the window context (and you're in a window).
As an aside: Plugins aren't in any perspective, although they can provide one or more perspectives.
The 2 most common contexts that key shortcuts are defined in are "In Windows" or in a specific part.
You have 3 choices.
1) define the commands and keybindings as if they all exist at the window level. That way there's no conflict.
2) define one command and one keybinding, and different handlers per perspective (or part). That's how a common action like Refresh is defined (one command, one keybinding, multiple handlers).
3) define 2 different contexts, one for each perspective, and activate/deactivate them on perspective change.

I don't understand choice 1. What do you mean? It is possible to give an
example?
