849 | /* TODO: On Windows, there are two ways of defining a dialog. |
850 | ||
851 | 1. Create a predefined dialog resource and include it in nt/emacs.rc. | |
852 | Using this method, we could then set the titles and make unneeded | |
853 | buttons invisible before displaying the dialog. Everything would | |
854 | be a fixed size though, so there is a risk that text does not | |
855 | fit on a button. | |
856 | 2. Create the dialog template in memory on the fly. This allows us | |
857 | to size the dialog and buttons dynamically, probably giving more | |
858 | natural looking results for dialogs with few buttons, and eliminating | |
859 | the problem of text overflowing the buttons. But the API for this is | |
860 | quite complex - structures have to be allocated in particular ways, | |
861 | text content is tacked onto the end of structures in variable length | |
862 | arrays with further structures tacked on after these, there are | |
863 | certain alignment requirements for all this, and we have to | |
864 | measure all the text and convert to "dialog coordinates" to figure | |
865 | out how big to make everything. | |
866 | ||
867 | For now, we'll just stick with menus for dialogs that are more | |
868 | complicated than simple yes/no type questions for which we can use | |
869 | the MessageBox function. | |
