3 | wxWindow is the base class for all windows. Any | |
4 | children of the window will be deleted automatically by the destructor | |
5 | before the window itself is deleted. | |

82 | ||
83 | \func{}{\destruct{wxWindow}}{\void} | |
84 | ||
85 | Destructor. Deletes all subwindows, then deletes itself. Instead of using | |
86 | the {\bf delete} operator explicitly, you should normally | |
87 | use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWindows | |
88 | can delete a window only when it is safe to do so, in idle time. | |

138 | ||
139 | \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp | |
140 | or {\tt wxBOTH}.} | |
141 | ||
142 | \wxheading{Remarks} | |
143 | ||
144 | The actual behaviour depends on the derived window. For a frame or dialog box, | |
145 | centring is relative to the whole display. For a panel item, centring is | |
146 | relative to the panel. | |

206 | \membersection{wxWindow::Close}\label{wxwindowclose} |
207 | ||
208 | \func{virtual bool}{Close}{\param{const bool}{ force = FALSE}} | |
209 | ||
210 | The purpose of this call is to provide a safer way of destroying a window than using | |
211 | the {\it delete} operator. | |
212 | ||
213 | \wxheading{Parameters} | |
214 | ||
215 | \docparam{force}{FALSE if the window's close handler should be able to veto the destruction | |
216 | of this window, TRUE if it cannot.} | |
217 | ||
218 | \wxheading{Remarks} | |
219 | ||
220 | Close calls the \helpref{close handler}{wxcloseevent} for the window, providing an opportunity for the window to | |
221 | choose whether to destroy the window. | |
222 | ||
223 | The close handler should check whether the window is being deleted forcibly, | |
224 | using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it should | |
225 | destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}. | |
226 | ||
227 | Applies to managed windows (wxFrame and wxDialog classes) only. | |
228 | ||
532372a3 JS |
229 | {\it Note} that calling Close does not guarantee that the window will be destroyed; but it |
230 | provides a way to simulate a manual close of a window, which may or may not be implemented by | |
231 | destroying the window. The default implementation of wxDialog::OnCloseWindow does not | |
232 | necessarily delete the dialog, since it will simply simulate an wxID\_CANCEL event which | |
233 | itself only hides the dialog. | |
234 | ||
235 | To guarantee that the window will be destroyed, call \helpref{wxWindow::Destroy}{wxwindowdestroy} instead. | |

247 | ||
248 | \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}} | |
249 | ||
250 | Converts a point or size from dialog units to pixels. | |
251 | ||
252 | For the x dimension, the dialog units are multiplied by the average character width | |
253 | and then divided by 4. | |
254 | ||
255 | For the y dimension, the dialog units are multiplied by the average character height | |
256 | and then divided by 8. | |
257 | ||
258 | \wxheading{Remarks} | |
259 | ||
260 | Dialog units are used for maintaining a dialog's proportions even if the font changes. | |
261 | Dialogs created using Dialog Editor optionally use dialog units. | |
262 | ||
263 | You can also use these functions programmatically. A convenience macro is defined: | |
264 | ||
265 | {\small | |
266 | \begin{verbatim} | |
267 | #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt) | |

937 | \func{void}{OnCharHook}{\param{wxKeyEvent\&}{ event}} | |
938 | ||
939 | This member is called to allow the window to intercept keyboard events | |
940 | before they are processed by child windows. | |
941 | ||
942 | \wxheading{Parameters} | |

946 | ||
947 | \wxheading{Remarks} | |
948 | ||
949 | This member function is called in response to a keypress, if the window is active. To intercept this event, | |
950 | use the EVT\_CHAR\_HOOK macro in an event table definition. If you do not process a particular | |
951 | keypress, call \helpref{wxEvent::Skip}{wxeventskip} to allow default processing. | |
952 | ||
953 | An example of using this function is in the implementation of escape-character processing for wxDialog, | |
954 | where pressing ESC dismisses the dialog by {\bf OnCharHook} 'forging' a cancel button press event. | |
955 | ||
956 | Note that the ASCII values do not have explicit key codes: they are passed as ASCII | |
957 | values. | |
958 | ||
959 | This function is only relevant to top-level windows (frames and dialogs), and under | |
6453876e RR |
960 | Windows only. Under GTK the normal EVT\_CHAR\_ event has the functionality, i.e. |
961 | you can intercepts it and if you don't call \helpref{wxEvent::Skip}{wxeventskip} | |
962 | the window won't get the event. | |

1019 | \func{void}{OnCloseWindow}{\param{wxCloseEvent\& }{event}} | |
1020 | ||
1021 | This is an event handler function called when the user has tried to close a a frame | |
1022 | or dialog box using the window manager (X) or system menu (Windows). It is | |
1023 | called via the \helpref{wxWindow::Close}{wxwindowclose} function, so | |
1024 | that the application can also invoke the handler programmatically. | |
1025 | ||
1026 | Use the EVT\_CLOSE event table macro to handle close events. | |
1027 | ||
1028 | You should check whether the application is forcing the deletion of the window | |
1029 | using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is TRUE, | |
1030 | destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}. | |
1031 | If not, it is up to you whether you respond by destroying the window. | |
1032 | ||
387a3b02 JS |
1033 | (Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of |
1034 | the window is required, test for the negative of CanVeto. If CanVeto returns FALSE, | |
1035 | it is not possible to skip window deletion.) | |
1036 | ||
1037 | If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to | |
1038 | let the calling code know that you did not destroy the window. This allows the \helpref{wxWindow::Close}{wxwindowclose} function | |
1039 | to return TRUE or FALSE depending on whether the close instruction was honoured or not. | |

1043 | The \helpref{wxWindow::OnClose}{wxwindowonclose} virtual function remains | |
1044 | for backward compatibility with earlier versions of wxWindows. The | |
1045 | default {\bf OnCloseWindow} handler for wxFrame and wxDialog will call {\bf OnClose}, | |
1046 | destroying the window if it returns TRUE or if the close is being forced. | |

1346 | terms of the client area, and are unscrolled, so you will need to do | |
1347 | some calculations using the current view position to obtain logical, | |
1348 | scrolled units. | |

1914 | \wxheading{Remarks} | |
1915 | ||
1916 | Let's say you wish to display 50 lines of text, using the same font. | |
1917 | The window is sized so that you can only see 16 lines at a time. | |
1918 | ||
1919 | You would use: | |
1920 | ||
1921 | {\small% | |
1922 | \begin{verbatim} | |
1923 | SetScrollbar(wxVERTICAL, 0, 16, 50); | |
1924 | \end{verbatim} | |
1925 | } | |
1926 | ||
1927 | Note that with the window at this size, the thumb position can never go | |
1928 | above 50 minus 16, or 34. | |
1929 | ||
1930 | You can determine how many lines are currently visible by dividing the current view | |
1931 | size by the character height in pixels. | |
1932 | ||
1933 | When defining your own scrollbar behaviour, you will always need to recalculate | |
1934 | the scrollbar settings when the window size changes. You could therefore put your | |
1935 | scrollbar calculations and SetScrollbar | |
1936 | call into a function named AdjustScrollbars, which can be called initially and also | |
1937 | from your \helpref{wxWindow::OnSize}{wxwindowonsize} event handler function. | |

1948 | |
1949 | Sets the page size of one of the built-in scrollbars. | |
1950 | ||
1951 | \wxheading{Parameters} | |
1952 | ||
1953 | \docparam{orientation}{Determines the scrollbar whose page size is to be set. May be wxHORIZONTAL or wxVERTICAL.} | |
1954 | ||
1955 | \docparam{pageSize}{Page size in scroll units.} | |

1957 | \docparam{refresh}{TRUE to redraw the scrollbar, FALSE otherwise.} | |
1958 | ||
1959 | \wxheading{Remarks} | |
1960 | ||
1961 | The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you | |
1962 | click on the area above/left of or below/right of the thumb. Normally you will want a whole visible | |
1963 | page to be scrolled, i.e. the size of the current view (perhaps the window client size). This | |
1964 | value has to be adjusted when the window is resized, since the page size will have changed. | |
1965 | ||
1966 | In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows | |
1967 | the thumb changes size to reflect the page size relative to the length of the document. When the | |
1968 | document size is only slightly bigger than the current view (window) size, almost all of the scrollbar | |
1969 | will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems) | |
1970 | disappear. | |
1971 | ||
1972 | Currently, this function should be called before SetPageRange, because of a quirk in the Windows | |
1973 | handling of pages and ranges. | |

2026 | The range of a scrollbar is the number of steps that the thumb may travel, rather than the total | |
fe604ccd JS |
2027 | object length of the scrollbar. If you are implementing a scrolling window, for example, you |
2028 | would adjust the scroll range when the window is resized, by subtracting the window view size from the | |
2029 | total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero | |
a660d684 KB |
2030 | and usually the scrollbar will be automatically hidden. |
