959 | ||
960 | 1. Create a predefined dialog resource and include it in nt/emacs.rc. | |
961 | Using this method, we could then set the titles and make unneeded | |
962 | buttons invisible before displaying the dialog. Everything would | |
963 | be a fixed size though, so there is a risk that text does not | |
964 | fit on a button. | |
965 | 2. Create the dialog template in memory on the fly. This allows us | |
966 | to size the dialog and buttons dynamically, probably giving more | |
967 | natural looking results for dialogs with few buttons, and eliminating | |
968 | the problem of text overflowing the buttons. But the API for this is | |
969 | quite complex - structures have to be allocated in particular ways, | |
970 | text content is tacked onto the end of structures in variable length | |
971 | arrays with further structures tacked on after these, there are | |
972 | certain alignment requirements for all this, and we have to | |
973 | measure all the text and convert to "dialog coordinates" to figure | |
974 | out how big to make everything. | |
975 | ||
976 | For now, we'll just stick with menus for dialogs that are more | |
977 | complicated than simple yes/no type questions for which we can use | |
978 | the MessageBox function. | |
