2776 Note: In many cases, properties of a frame are available as specifiers

2777 instead of through the frame-properties mechanism.
|

2778
|
|
|
2779 Here is a list of recognized frame properties, other than those
|
|
|
2780 documented in `set-frame-properties' (they can be queried and
|
|
|
2781 set at any time, except as otherwise noted):
|
|
|
2782
|
|
|
2783 window-id The X window ID corresponding to the
|
|
|
2784 frame. May be set only at startup, and
|
|
|
2785 only if external widget support was
|
|
|
2786 compiled in; doing so causes the frame
|
|
|
2787 to be created as an "external widget"
|
|
|
2788 in another program that uses an existing
|
|
|
2789 window in the program rather than creating
|
|
|
2790 a new one.
|
|
|
2791 initially-unmapped If non-nil, the frame will not be visible
|
|
|
2792 when it is created. In this case, you
|
|
|
2793 need to call `make-frame-visible' to make
|
|
|
2794 the frame appear.
|
|
|
2795 popup If non-nil, it should be a frame, and this
|
|
|
2796 frame will be created as a "popup" frame
|
|
|
2797 whose parent is the given frame. This
|
|
|
2798 will make the window manager treat the
|
|
|
2799 frame as a dialog box, which may entail
|
|
|
2800 doing different things (e.g. not asking
|
|
|
2801 for positioning, and not iconifying
|
|
|
2802 separate from its parent).
|
|
|
2803 inter-line-space Not currently implemented.
|
|
|
2804 toolbar-shadow-thickness Thickness of toolbar shadows.
|
|
|
2805 background-toolbar-color Color of toolbar background.
|
|
|
2806 bottom-toolbar-shadow-color Color of bottom shadows on toolbars.
|
|
|
2807 (*Not* specific to the bottom-toolbar.)
|
|
|
2808 top-toolbar-shadow-color Color of top shadows on toolbars.
|
|
|
2809 (*Not* specific to the top-toolbar.)
|
|
|
2810 internal-border-width Width of internal border around text area.
|
|
|
2811 border-width Width of external border around text area.
|
|
|
2812 top Y position (in pixels) of the upper-left
|
|
|
2813 outermost corner of the frame (i.e. the
|
|
|
2814 upper-left of the window-manager
|
|
|
2815 decorations).
|
|
|
2816 left X position (in pixels) of the upper-left
|
|
|
2817 outermost corner of the frame (i.e. the
|
|
|
2818 upper-left of the window-manager
|
|
|
2819 decorations).
|
|
|
2820 border-color Color of external border around text area.
|
|
|
2821 cursor-color Color of text cursor.
|
|
|

2824 to all frames, not just X frames.
