| 52 | // there are two possible ways to create the radio buttons: either as children |
| 53 | // of the radiobox or as siblings of it - allow playing with both variants for |
| 54 | // now, eventually we will choose the best one for our purposes |
| 55 | // |
| 56 | // two main problems are the keyboard navigation inside the radiobox (arrows |
| 57 | // should switch between buttons, not pass focus to the next control) and the |
| 58 | // tooltips - a tooltip is associated with the radiobox itself, not the |
| 59 | // children... |
| 60 | // |
| 61 | // the problems with setting this to 1: |
| 62 | // a) Alt-<mnemonic of radiobox> isn't handled properly by IsDialogMessage() |
| 63 | // because it sets focus to the next control accepting it which is not a |
| 64 | // radio button but a radiobox sibling in this case - the only solution to |
| 65 | // this would be to handle Alt-<mnemonic> ourselves |
| 66 | // b) the problems with setting radiobox colours under Win98/2K were reported |
| 67 | // but I couldn't reproduce it so I have no idea about what causes it |
| 68 | // |
| 69 | // the problems with setting this to 0: |
| 70 | // a) the tooltips are not shown for the radiobox - possible solution: make |
| 71 | // TTM_WINDOWFROMPOS handling code in msw/tooltip.cpp work (easier said than |
| 72 | // done because I don't know why it doesn't work) |
