3027 | NB: there used to be some code here which set the initial size of the | |

3029 | specified. This was wrong because wxWidgets programs often assume | |
3030 | that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke | |
3031 | it. To see why, you should understand that Windows sends WM_SIZE from | |
3032 | inside ::CreateWindow() anyhow. However, ::CreateWindow() is called | |
3033 | from some base class ctor and so this WM_SIZE is not processed in the | |
3034 | real class' OnSize() (because it's not fully constructed yet and the | |
3035 | event goes to some base class OnSize() instead). So the WM_SIZE we | |
3036 | rely on is the one sent when the parent frame resizes its children | |
3037 | but here is the problem: if the child already has just the right | |
3038 | size, nothing will happen as both wxWidgets and Windows check for | |
3039 | this and ignore any attempts to change the window size to the size it | |
3040 | already has - so no WM_SIZE would be sent. | |

3048 | // empty frame of most of wxWidgets samples for example) | |
3049 | // | |
3050 | // 2. it is buggy for frames with wxFRAME_TOOL_WINDOW style for which | |
3051 | // the default is for whatever reason 8*8 which breaks client <-> | |
3052 | // window size calculations (it would be nice if it didn't, but it | |
