Every application starter has some preferences you can set from their context menu. Usually applications and folders have the same preferences as in Konqueror. Only the applications which are located in the K Menu (for experienced users: those which have a *.desktop in the applnk dir) have a special kind of config dialog.
Here you can see some stats about the application link. You can also choose an icon by clicking on the icon button and change the filename of the link file. This may be useful if you want the icon on the panel behave different to the analogue one in the K Menu.
Here you can set the permissions of the link file. Please refer to the manuals or handbooks of your operating system for more about permissions.
You can set the behaviour of the application when it's executed on this page.
Usually, there is only the name of the binary that has to be started when clicking on the icon. You can search for another application to be started by clicking the Browse button and/or add special command line parameters to the application.
Sorry, this feature is not implemented yet ;-(
If this box is checked, the application will be executed in a terminal window. You can also add special Terminal options.
Checking this option will let the application start with the permission of the user you typed in the field Username. You will be prompted for the user's password on application start. This option may be very useful if you want to start some applications as superuser.
If you set a name and a comment, they will be shown as tooltips of the start icons in the style "Name - Comment".
In the File Types section you can choose what kinds of filetypes are handled by this application. Please refer to Konqueror handbook for more about this.
