143 | POSITION is a position specification. This is either a mouse button | |
144 | event or a list ((XOFFSET YOFFSET) WINDOW) where XOFFSET and YOFFSET | |
145 | are positions in pixels from the top left corner of WINDOW's frame | |
146 | \(WINDOW may be a frame object instead of a window). This controls the | |
147 | position of the center of the first line in the first pane of the | |
148 | menu, not the top left of the menu as a whole. If POSITION is t, it | |
149 | means to use the current mouse position. | |
150 | ||
151 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap. | |
152 | The menu items come from key bindings that have a menu string as well as | |
153 | a definition; actually, the \"definition\" in such a key binding looks like | |
154 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into | |
155 | the keymap as a top-level element. | |
156 | ||
157 | If REAL-DEFINITION is nil, that puts a nonselectable string in the menu. | |
158 | Otherwise, REAL-DEFINITION should be a valid key binding definition. | |
159 | ||
160 | You can also use a list of keymaps as MENU. Then each keymap makes a | |
161 | separate pane. When MENU is a keymap or a list of keymaps, the return | |
162 | value is a list of events. | |
163 | ||
164 | Alternatively, you can specify a menu of multiple panes with a list of | |
165 | the form (TITLE PANE1 PANE2...), where each pane is a list of | |
166 | form (TITLE ITEM1 ITEM2...). | |
167 | Each ITEM is normally a cons cell (STRING . VALUE); but a string can | |
168 | appear as an item--that makes a nonselectable line in the menu. | |
169 | With this form of menu, the return value is VALUE from the chosen item. | |
170 | ||
171 | If POSITION is nil, don't display the menu at all, just precalculate the | |
172 | cached information about equivalent key sequences. */) | |

1244 | /* TODO: On Windows, there are two ways of defining a dialog. |
1245 | ||
1246 | 1. Create a predefined dialog resource and include it in nt/emacs.rc. | |
1247 | Using this method, we could then set the titles and make unneeded | |
1248 | buttons invisible before displaying the dialog. Everything would | |
1249 | be a fixed size though, so there is a risk that text does not | |
1250 | fit on a button. | |
1251 | 2. Create the dialog template in memory on the fly. This allows us | |
1252 | to size the dialog and buttons dynamically, probably giving more | |
1253 | natural looking results for dialogs with few buttons, and eliminating | |
1254 | the problem of text overflowing the buttons. But the API for this is | |
1255 | quite complex - structures have to be allocated in particular ways, | |
1256 | text content is tacked onto the end of structures in variable length | |
1257 | arrays with further structures tacked on after these, there are | |
1258 | certain alignment requirements for all this, and we have to | |
1259 | measure all the text and convert to "dialog coordinates" to figure | |
1260 | out how big to make everything. | |
1261 | ||
1262 | For now, we'll just stick with menus for dialogs that are more | |
1263 | complicated than simple yes/no type questions for which we can use | |
1264 | the MessageBox function. | |
