440 If an X error occurs which we are not expecting, we have no alternative
|
|
|
441 but to print it to stderr. It would be nice to stuff it into a pop-up
|
|
|
442 buffer, or to print it in the minibuffer, but that's not possible, because
|
|
|
443 one is not allowed to do any I/O on the display connection from an error
|
|
|
444 handler. The guts of Xlib expect these functions to either return or exit.
|
|
|
445
|
|
|
446 However, there are occasions when we might expect an error to reasonably
|
|
|
447 occur. The interface to this is as follows:
|
|
|
448
|
|
|
449 Before calling some X routine which may error, call
|
|
|
450 expect_x_error (dpy);
|
|
|
451
|
|
|
452 Just after calling the X routine, call either:
|
|
|
453
|
|
|
454 x_error_occurred_p (dpy);
|
|
|
455
|
|
|
456 to ask whether an error happened (and was ignored), or:
|
|
|
457
|
|
|
458 signal_if_x_error (dpy, resumable_p);
|
|
|
459
|
|
|
460 which will call Fsignal() with args appropriate to the X error, if there
|
|
|
461 was one. (Resumable_p is whether the debugger should be allowed to
|
|
|
462 continue from the call to signal.)
|
|
|
463
|
|
|
464 You must call one of these two routines immediately after calling the X
|
|
|
465 routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT.

826 The first arg is the name of the resource to retrieve, such as \"font\".
|
|
|
827 The second arg is the class of the resource to retrieve, like \"Font\".
|
|
|
828 The third arg should be one of the symbols 'string, 'integer, 'natnum, or

829 'boolean, specifying the type of object that the database is searched for.
|

830 The fourth arg is the locale to search for the resources on, and can

831 currently be a a buffer, a frame, a device, or 'global. If omitted, it
|

832 defaults to 'global.

833 The fifth arg is the device to search for the resources on. (The resource

834 database for a particular device is constructed by combining non-device-
|
|
|
835 specific resources such any command-line resources specified and any

836 app-defaults files found [or the fallback resources supplied by XEmacs,
|

837 if no app-defaults file is found] with device-specific resources such as

838 those supplied using xrdb.) If omitted, it defaults to the device of

840 and otherwise defaults to the value of `default-x-device'.

842 bogus resource specification was retrieved (e.g. if a non-integer was

843 given when an integer was requested). In this case, a warning is issued

851 \"modeline.attributeFont\", and CLASS \"Face.AttributeFont\".

|
|
|
867 (x-get-resource \"foreground\" \"Foreground\" 'string SOME-FRAME)
|
|
|
868
|
|
|
869 is an interface to a C call something like

|
|
870
|
|
|
871 XrmGetResource (db, \"xemacs.frame.FRAME-NAME.foreground\",
|
|
|

|
|
|
873 \"String\");
|
|

|
877 (x-get-resource \"foreground\" \"Foreground\" 'string SOME-DEVICE)
|
|

878

894
|
|
|
895 Note that for 'global, no prefix is added other than that of the

896 application itself; thus, you can use this locale to retrieve

897 arbitrary application resources, if you really want to.
|

898

899 The returned value of this function is nil if the queried resource is not

901 `integer', an integer is returned. If the third arg is `boolean', then the
|
|
|
902 returned value is the list (t) for true, (nil) for false, and is nil to
|
|
|
903 mean ``unspecified.''
