2d84cc27 MK |
72 | Ediff provides a choice of two functions: `ediff-setup-windows-plain', for |
73 | doing everything in one frame and `ediff-setup-windows-multiframe', which sets | |
74 | the control panel in a separate frame. By default, the appropriate function is | |
75 | chosen automatically depending on the current window system. | |
76 | However, `ediff-toggle-multiframe' can be used to toggle between the multiframe | |
77 | display and the single frame display. | |
78 | If the multiframe function detects that one of the buffers A/B is seen in some | |
79 | other frame, it will try to keep that buffer in that frame. | |
80 | ||
81 | If you don't like any of the two provided functions, write your own one. | |
475f9031 KH |
82 | The basic guidelines: |
83 | 1. It should leave the control buffer current and the control window | |
6628e7f8 DL |
84 | selected. |
85 | 2. It should set `ediff-window-A', `ediff-window-B', `ediff-window-C', | |
86 | and `ediff-control-window' to contain window objects that display | |
475f9031 KH |
87 | the corresponding buffers. |
88 | 3. It should accept the following arguments: | |
89 | buffer-A, buffer-B, buffer-C, control-buffer | |
90 | Buffer C may not be used in jobs that compare only two buffers. | |
91 | If you plan to do something fancy, take a close look at how the two | |
ddc90f39 | 92 | provided functions are written." |
