| 2828 These override what is specified in the resource database and in | |
| 2829 `default-frame-plist', but are overridden by the arguments to the | |
| 2830 particular call to `make-frame'. | |
| 2831 | |
| 2832 Note: In many cases, properties of a frame are available as specifiers | |
| 2833 instead of through the frame-properties mechanism. | |
| 2834 | |
| 2835 Here is a list of recognized frame properties, other than those | |
| 2836 documented in `set-frame-properties' (they can be queried and | |
| 2837 set at any time, except as otherwise noted): | |
| 2838 | |
| 2839 window-id The X window ID corresponding to the | |
| 2840 frame. May be set only at startup, and | |
| 2841 only if external widget support was | |
| 2842 compiled in; doing so causes the frame | |
| 2843 to be created as an "external widget" | |
| 2844 in another program that uses an existing | |
| 2845 window in the program rather than creating | |
| 2846 a new one. | |
| 2847 initially-unmapped If non-nil, the frame will not be visible | |
| 2848 when it is created. In this case, you | |
| 2849 need to call `make-frame-visible' to make | |
| 2850 the frame appear. | |
| 2851 popup If non-nil, it should be a frame, and this | |
| 2852 frame will be created as a "popup" frame | |
| 2853 whose parent is the given frame. This | |
| 2854 will make the window manager treat the | |
| 2855 frame as a dialog box, which may entail | |
| 2856 doing different things (e.g. not asking | |
| 2857 for positioning, and not iconifying | |
| 2858 separate from its parent). | |
| 2747 | 2859 override-redirect If non-nil, the frame will not be subject to |
| 2860 window-manager control. In particular, it | |
| 2861 will lack decorations, for more attractive | |
| 2862 appearance of balloon help, aka tooltips. | |
| 428 | 2863 inter-line-space Not currently implemented. |
| 2864 toolbar-shadow-thickness Thickness of toolbar shadows. | |
| 2865 background-toolbar-color Color of toolbar background. | |
| 2866 bottom-toolbar-shadow-color Color of bottom shadows on toolbars. | |
| 2867 (*Not* specific to the bottom-toolbar.) | |
| 2868 top-toolbar-shadow-color Color of top shadows on toolbars. | |
| 2869 (*Not* specific to the top-toolbar.) | |
| 2870 internal-border-width Width of internal border around text area. | |
| 2871 border-width Width of external border around text area. | |
| 2872 top Y position (in pixels) of the upper-left | |
| 2873 outermost corner of the frame (i.e. the | |
| 2874 upper-left of the window-manager | |
| 2875 decorations). | |
| 2876 left X position (in pixels) of the upper-left | |
| 2877 outermost corner of the frame (i.e. the | |
| 2878 upper-left of the window-manager | |
| 2879 decorations). | |
| 2880 border-color Color of external border around text area. | |
| 2881 cursor-color Color of text cursor. | |

| 2883 See also `default-frame-plist', which specifies properties which apply | |
