However, the -\fBEditRes\fP protocol requires the application to link with the -\fBEditRes\fP -routines in the Xmu library and Xmu is not used by all applications that -use Motif. Also, the \fBEditRes\fP protocol uses ClientMessage, -whereas the -\fBRCM\fP \fBIntrinsics\fP hooks use \fBPropertyNotify\fP events. -.LP -X Properties and the \fBPropertyNotify\fP events are used -to implement \fBRCM\fP and -allow on-the-fly resource customization. When the X Toolkit is -initialized, two atoms are interned with the strings -\fICustom Init\fP and -\fICustom Data\fP. Both -.PN _XtCreatePopupShell -and -.PN _XtAppCreateShell -register a \fBPropertyNotify\fP event handler to handle these properties. -.LP -A customization tool uses the \fICustom Init\fP property to \fIping\fP an -application to get the application's toplevel window. When the -application's property notify event handler is invoked, the handler -deletes the property. No data is transferred in this property. -.LP -A customization tool uses the \fICustom Data\fP property to tell an -application that it should change a resource's value. The data in -the property contains the length of the resource name (the number -of bytes in the resource name), the resource name and the new -value for the resource. This property's type is \fBXA_STRING\fP and -the format of the string is: -.IP 1. 5 -The length of the resource name (the number of bytes in -the resource name) -.IP 2. 5 -One space character -.IP 3. 5 -The resource name -.IP 4. 5 -One space character -.IP 5. 5 -The resource value -.LP -When setting the application's resource, the event handler calls -functions to walk the application's widget tree, determining which -widgets are affected by the resource string, and then applying the value -with -.PN XtSetValues. -As the widget tree is recursively descended, at -each level in the widget tree a resource part is tested for a match. -When the entire resource string has been matched, the value is applied -to the widget or widgets. -.LP -Before a value is set on a widget, it is first determined if the last -part of the resource is a valid resource for that widget. It must also -add the resource to the application's resource database and then query -it using specific resource strings that is builds from the widget -information. - - |
