648 If an X error occurs which we are not expecting, we have no alternative
|
|
|
649 but to print it to stderr. It would be nice to stuff it into a pop-up
|
|
|
650 buffer, or to print it in the minibuffer, but that's not possible, because
|
|
|
651 one is not allowed to do any I/O on the display connection from an error
|
|
|
652 handler. The guts of Xlib expect these functions to either return or exit.
|
|
|
653
|
|
|
654 However, there are occasions when we might expect an error to reasonably
|
|
|
655 occur. The interface to this is as follows:
|
|
|
656
|
|
|
657 Before calling some X routine which may error, call
|
|
|
658 expect_x_error (dpy);
|
|
|
659
|
|
|
660 Just after calling the X routine, call either:
|
|
|
661
|
|
|
662 x_error_occurred_p (dpy);
|
|
|
663
|
|
|
664 to ask whether an error happened (and was ignored), or:
|
|
|
665
|
|
|
666 signal_if_x_error (dpy, resumable_p);
|
|
|
667
|
|
|
668 which will call Fsignal() with args appropriate to the X error, if there
|
|
|
669 was one. (Resumable_p is whether the debugger should be allowed to
|
|
|
670 continue from the call to signal.)
|
|
|
671
|
|
|
672 You must call one of these two routines immediately after calling the X
|
|
|
673 routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT.

1045 Retrieve an X resource from the resource manager.

183

1047 The first arg is the name of the resource to retrieve, such as "font".

1048 The second arg is the class of the resource to retrieve, like "Font".
|
|
0
|
1049 The third arg should be one of the symbols 'string, 'integer, 'natnum, or
|
|
|
1050 'boolean, specifying the type of object that the database is searched for.
|
|
|
1051 The fourth arg is the locale to search for the resources on, and can
|
|
|
1052 currently be a a buffer, a frame, a device, or 'global. If omitted, it
|
|

1053 defaults to 'global.

1054 The fifth arg is the device to search for the resources on. (The resource

1060 LOCALE, if a device can be derived (i.e. if LOCALE is a frame or device),
|
|
|
1061 and otherwise defaults to the value of `default-x-device'.
|

1062 The sixth arg NOERROR, if non-nil, means do not signal an error if a
|
|
|
1063 bogus resource specification was retrieved (e.g. if a non-integer was

1064 given when an integer was requested). In this case, a warning is issued

1069

1070 If you want to search for a subresource, you just need to specify the

1072 "modeline.attributeFont", and CLASS "Face.AttributeFont".
