The displayed date range is the one specified by the Date class. We display as many months as we have space in the control. The user can switch between months using a ContextMenu (clicking on the month's name) or via two ScrollButtons in-between the months. -------------------------------------------------------------------------- WinBits WB_BORDER We draw a border around the window. WB_TABSTOP Keyboard control is possible. We get the focus, when the user clicks in the Control. -------------------------------------------------------------------------- We set and get the selected date by SetCurDate()/GetCurDate(). If the user selects a date Select() is called. If the user double clicks DoubleClick() is called. -------------------------------------------------------------------------- CalcWindowSizePixel() calculates the window size in pixel that is needed to display a certain number of months. -------------------------------------------------------------------------- SetSaturdayColor() and SetSundayColor() set a special color for Saturdays and Sundays. AddDateInfo() marks special days. With that we can set e.g. public holidays to another color or encircle them (for e.g. appointments). If we do not supply a year in the date, the day is used in EVERY year. AddDateInfo() can also add text for every date, which is displayed if the BalloonHelp is enabled. In order to not have to supply all years with the relevant data, we call the RequestDateInfo() handler if a new year is displayed. We can then query the year in the handler with GetRequestYear(). -------------------------------------------------------------------------- In order to display a ContextMenu for a date, we need to override the Command handler. GetDate() can infer the date from the mouse's position. If we use the keyboard, the current date should be use. If a ContextMenu is displayed, the baseclass' handler must not be called. -------------------------------------------------------------------------- SetNoSelection() deselects everything. SetCurDate() does not select the current date, but only defines the focus rectangle. GetSelectDateCount()/GetSelectDate() query the selected range. IsDateSelected() queries for the status of a date. The SelectionChanging() handler is being called while a user selects a date. In it, we can change the selected range. E.g. if we want to limit or extend the selected range. The selected range is realised via SelectDate() and SelectDateRange() and queried with GetSelectDateCount()/GetSelectDate(). IsSelectLeft() returns the direction of the selection: sal_True is a selection to the left or up sal_False is a selection to the right or down -------------------------------------------------------------------------- If the DateRange area changes and we want to take over the selection, we should only do this is if IsScrollDateRangeChanged() returns sal_True. This method returns sal_True if the area change was triggered by using the ScrollButtons and sal_False if it was triggered by Resize(), other method calls or by ending a selection. *************************************************************************/ typedef std::set IntDateSet; class Calendar final : public Control { std::unique_ptr mpSelectTable; std::unique_ptr mpOldSelectTable; OUString maDayTexts[31]; OUString maDayText; OUString maWeekText; CalendarWrapper maCalendarWrapper; tools::Rectangle maPrevRect; tools::Rectangle maNextRect; OUString maDayOfWeekText; sal_Int32 mnDayOfWeekAry[8]; Date maOldFormatFirstDate; Date maOldFormatLastDate; Date maFirstDate; Date maOldFirstDate; Date maCurDate; Date maOldCurDate; Color maSelColor; Color maOtherColor; sal_Int32 mnDayCount; tools::Long mnDaysOffX; tools::Long mnWeekDayOffY; tools::Long mnDaysOffY; tools::Long mnMonthHeight; tools::Long mnMonthWidth; tools::Long mnMonthPerLine; tools::Long mnLines; tools::Long mnDayWidth; tools::Long mnDayHeight; WinBits mnWinStyle; sal_Int16 mnFirstYear; sal_Int16 mnLastYear; bool mbCalc:1, mbFormat:1, mbDrag:1, mbMenuDown:1, mbSpinDown:1, mbPrevIn:1, mbNextIn:1; Link maSelectHdl; Link maActivateHdl; using Control::ImplInitSettings; using Window::ImplInit; void ImplInit( WinBits nWinStyle ); void ImplInitSettings(); virtual void ApplySettings(vcl::RenderContext& rRenderContext) override; void ImplFormat(); sal_uInt16 ImplDoHitTest( const Point& rPos, Date& rDate ) const; void ImplDrawSpin(vcl::RenderContext& rRenderContext); void ImplDrawDate(vcl::RenderContext& rRenderContext, tools::Long nX, tools::Long nY, sal_uInt16 nDay, sal_uInt16 nMonth, sal_Int16 nYear, bool bOther, sal_Int32 nToday); void ImplDraw(vcl::RenderContext& rRenderContext); void ImplUpdateDate( const Date& rDate ); void ImplUpdateSelection( IntDateSet* pOld ); void ImplMouseSelect( const Date& rDate, sal_uInt16 nHitTest ); void ImplUpdate( bool bCalcNew = false ); void ImplScrollCalendar( bool bPrev ); void ImplShowMenu( const Point& rPos, const Date& rDate ); void ImplTracking( const Point& rPos, bool bRepeat ); void ImplEndTracking( bool bCancel ); DayOfWeek ImplGetWeekStart() const; virtual Size GetOptimalSize() const override; public: Calendar( vcl::Window* pParent, WinBits nWinStyle ); virtual ~Calendar() override; virtual void dispose() override; virtual void MouseButtonDown( const MouseEvent& rMEvt ) override; virtual void Tracking( const TrackingEvent& rMEvt ) override; virtual void KeyInput( const KeyEvent& rKEvt ) override; virtual void Paint( vcl::RenderContext& rRenderContext, const tools::Rectangle& rRect ) override; virtual void Resize() override; virtual void GetFocus() override; virtual void LoseFocus() override; virtual void RequestHelp( const HelpEvent& rHEvt ) override; virtual void Command( const CommandEvent& rCEvt ) override; virtual void StateChanged( StateChangedType nStateChange ) override; virtual void DataChanged( const DataChangedEvent& rDCEvt ) override; void Select(); Date GetFirstSelectedDate() const; void SetCurDate( const Date& rNewDate ); void SetFirstDate( const Date& rNewFirstDate ); const Date& GetFirstDate() const { return maFirstDate; } Date GetLastDate() const { return GetFirstDate() + mnDayCount; } Date GetFirstMonth() const; Date GetLastMonth() const; sal_uInt16 GetMonthCount() const; bool GetDate( const Point& rPos, Date& rDate ) const; tools::Rectangle GetDateRect( const Date& rDate ) const; void EndSelection(); Size CalcWindowSizePixel() const; void SetSelectHdl( const Link& rLink ) { maSelectHdl = rLink; } void SetActivateHdl( const Link& rLink ) { maActivateHdl = rLink; } }; #endif // INCLUDED_VCL_CALENDAR_HXX /* vim:set shiftwidth=4 softtabstop=4 expandtab: */ value='distro/vector/vector-7.5.9-release'>distro/vector/vector-7.5.9-release LibreOffice 核心代码仓库文档基金会
