In the "computing" screen can be added new applications.
To add a new application, a template must be used, and the window class for that application must be known. Window class is a property of every X11 application.
The WM_CLASS property (of type STRING without control characters) contains two consecutive null-terminated strings. These specify the Instance and Class names to be used by both the client and the window manager for looking up resources for the application or as identifying information.
Contents
On a LinuxMCE computer
Go to computing screen.
Press admin => firefox should appear
Press Ctrl-Alt-F2 => you are at a login prompt
Log in
run the command
export DISPLAY=:0
now you can launch GUI applications from this console
launch your application
Press Ctrl-Alt-F7 and wait until your application appears
Press Ctrl-Alt-F3 and log in again
type these commands
export DISPLAY=:0 xprop | grep WM_CLASS
Press Ctrl-Alt-F7 => the cursor changed his shape to "+"
Click somewhere in your application
=> the cursor changes back to "normal" cursor
Press Ctrl-Alt-F3 and look into your console: a line like this should appear
WM_CLASS(STRING) = "class_instance", "class_Name"
class_instance.class_Name is the string that will be used in the template for your application Remember this string, and pay attention to lowercase and uppercase characters
You can close your application an your consoles now
On another computer
Launch a terminal
Launch your application
Type in your terminal:
xprop | grep WM_CLASS
=> the cursor changed his shape to "+"
Click somewhere in your application
=> the cursor changes back to "normal" cursor
Look in your terminal: a line like this should appear
WM_CLASS(STRING) = "class_instance", "class_Name"
class_instance.class_Name is the string that will be used in the template for your application Remember this string, and pay attention to lowercase and uppercase characters
You can close your application an your terminal now
Using the WM_CLASS string in the template
- A new application can be added to the computing screen from the media director detail page. There is a button Edit for the Computing application:
- The new popup window - Edit Computing Applications, will be opened with list of all available computing applications:
- Press the link on the bottom of that window to go to edit screen:
- There is another link - Add quick start template on the Edit Quick Start templates which opens a form:
where you should type description for your app, the path to the binary and Window class from the previous steps. Here is an example for Skype:
- After submitting that form, close the Edit Quick Start templates and refresh the page Edit Computing Applications. Then tick the checkbox near added application to activate it, save it and close the window.
That's it. After a quick reloading of router the new application should appear on the left side of the computing screen.
Troubleshooting
By some reason, after adding new application the path is displayed for each apps on the computing screen instead of description. Probably the Orbiter should be fully regenerated.
