Mouse
Relative mouse
The relative mouse feature determines how far the mouse has moved since the last frame within a window or screen. The relative mouse uses the pixel delta between the mouse movements. When you change, for example, the direction of the camera using mouse controls, the feature is efficient. Apps also often hide the mouse cursor because the position of the cursor relative to the screen coordinates isn’t relevant, when manipulating a 3-D object or scene.
Relative mouse support provides an option to interpret the mouse position in a relative rather than an absolute manner. The interpretation is required for applications that demand relative mouse input rather than absolute.
You can configure the feature both on a per-user and a per-session basis, which gives more granular control on the feature availability.
Note
This feature can be applied in a published desktop session only.
Configuring the feature using the Registry Editor or the default.ica file allows the setting to be persistent even after the session is terminated.
Configuring relative mouse using the Registry editor
To configure the feature, set the following registry keys as applicable and then restart the session for the changes to take effect:
To make the feature available on a per-session basis:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\RelativeMouse
To make the feature available on a per-user basis:
HKEY_CURRENT_USER\Software\Policies\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\RelativeMouse
- Name: Mouse
- Type: REG_SZ
- Value: True
Note:
- The values set in the Registry editor take precedence over the ICA file settings.
- The values set in HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER must be the same. Different values might cause conflicts.
Configuring the relative mouse using the default.ica file
- Open the default.ica file typically at
C:\inetpub\wwwroot\Citrix\<site name>\conf\default.ica, where sitename is the name specified for the site while creating. For StoreFront customers, the default.ica file is typically atC:\inetpub\wwwroot\Citrix\<Storename>\App_Data\default.ica, wherestorenameis the name set for the store when created. - Add a key by name RelativeMouse in the WFClient section. Set its value to the same configuration as the JSON object.
- Set the value as required:
- true – To enable relative mouse
- false – To disable relative mouse
- Restart the session for the changes to take effect.
Note:
The values set in the Registry editor take precedence over the ICA file settings.
