6260 | on X where the usual policy is point-to-focus. However, this | |
6261 | behaviour would be very odd on Windows where the usual policy is | |
6262 | click-to-focus. | |
6263 | ||
6264 | On X, if the mouse happens to be over the raised frame, it gets | |
6265 | input focus anyway (so the window with focus will never be | |
6266 | completely obscured) - if not, then just moving the mouse over it | |
6267 | is sufficient to give it focus. On Windows, the user must actually | |
6268 | click on the frame (preferrably the title bar so as not to move | |
6269 | point), which is more awkward. Also, no other Windows program | |
6270 | raises a window to the top but leaves another window (possibly now | |
6271 | completely obscured) with input focus. | |
6272 | ||
6273 | Because there is a system setting on Windows that allows the user | |
6274 | to choose the point to focus policy, we make the strict semantics | |
6275 | optional, but by default we grab focus when raising. */ | |
