| 27 short-sighted people who designed the monstrosities known as | |
| 28 Xt and ICCCM. | |
| 29 */ | |
| 30 | |
| 31 /* | |
| 32 This widget is not actually Emacs-specific; perhaps there could | |
| 33 be a better name than "EmacsShell". What it does is work around | |
| 34 a limitation in Xt in correctly dealing with the window-manager | |
| 35 size hints with applications that | |
| 36 | |
| 37 (a) dynamically change their window size | |
| 38 (b) have a cell size (width-inc and height-inc) other than 1 | |
| 39 | |
| 40 and | |
| 41 | |
| 42 (c) cannot predict in advance exactly what size their shell will be | |
| 43 (This is the more common situation, when you have a number | |
| 44 of widgets, each with their own size ideas) | |
| 45 | |
| 46 This widget assumes that your program contains a fixed "base size" | |
| 47 plus some number of cells (e.g. character cells). The WMShell | |
| 48 resources "widthInc" and "heightInc" specify the size of a | |
| 49 character cell, and the window manager will report the app's | |
| 50 size in cells rather than in pixels. | |
| 51 | |
| 52 If you use this widget, do not use the WMShell resources | |
| 53 "baseWidth", "baseHeight", "minWidth", or "minHeight". | |
| 54 Instead, use "widthCells" and "heightCells" to specify the | |
| 55 current size in cells (you must keep this up-to-date), | |
| 56 and "minWidthCells" and "minHeightCells" to specify the | |
| 57 minimum size in cells. | |
| 58 | |
| 59 Every time that the program issues a size command, the | |
| 60 "baseWidth", "baseHeight", "minWidth", and "minHeight" fields | |
| 61 of the WM_NORMAL_HINTS property will be updated to stay in | |
| 62 line with the resource values specified above. The calculations | |
| 63 are done once the desired shell size is known but before the | |
| 64 window-manager size-change request is issued. (We must do it | |
| 65 at this time because before then we don't know what size we | |
| 66 will request, and after the request the deed has already | |
| 67 been done.) | |
| 68 | |
| 69 After you change the "baseWidth", "baseHeight", "minWidth", | |
| 70 or "minHeight" resources, you need to call | |
| 71 EmacsShellUpdateSizeHints() to manually update the size | |
| 72 hints, except in the following two circumstances: | |
| 73 | |
| 74 (a) you are about to make a geometry request. | |
| 75 (b) you are changing only "baseWidth" and "baseHeight" | |
| 76 from within a resize procedure. (In this case, | |
| 77 the size hints are already correct.) | |
