Pointer for Nitpicker with optional hover-sensitive shape support
|
|
|
|
Per default the standard "big mouse" pointer is rendered on screen.
|
|
|
|
Additionally, 'pointer' supports to render "pointer shapes" when hovering
|
|
Nitpicker sessions for which a shape was reported. This feature must be
|
|
enabled with the '<config shapes="yes"/>' option. When enabled, the
|
|
'pointer' component announces a 'Report' service for custom pointer shapes
|
|
and requests ROM sessions for Nitpicker's 'hover' and 'xray' reports. The
|
|
mapping between hovered Nitpicker sessions and applications can be achieved
|
|
with report session label rewriting:
|
|
|
|
! <start name="shape-arrow">
|
|
! <binary name="test-pointer"/>
|
|
! <resource name="RAM" quantum="2M"/>
|
|
! <config shape="arrow"/>
|
|
! <route>
|
|
! <service name="PD"> <parent/> </service>
|
|
! <service name="ROM"> <parent/> </service>
|
|
! <service name="CPU"> <parent/> </service>
|
|
! <service name="LOG"> <parent/> </service>
|
|
! <service name="Report" label="shape">
|
|
! <child name="pointer" label="test-label-arrow -> testnit"/>
|
|
! </service>
|
|
! </route>
|
|
! </start>
|
|
|
|
In the example above, which is from 'pointer.run', the 'shape-arrow' component
|
|
reports an arrow shape with the label "shape". By rewriting the label of the
|
|
report, the shape will be drawn for the 'test-label-arrow' component, which
|
|
is reported by Nitpicker with the label 'test-label-arror -> testnit' when
|
|
hovered.
|
|
|
|
When configured with '<config shapes="yes" verbose="yes"/>', the 'pointer'
|
|
component prints the labels of hovered Nitpicker sessions and received shape
|
|
reports to the 'LOG' service.
|
|
|
|
The most common use cases for pointer shapes are VirtualBox, which reports
|
|
the guest-pointer shapes if Guest Additions are installed, and Qt applications.
