public class BasicMonthViewUI
extends MonthViewUI

Base implementation of the JXMonthView UI.

Note: The api changed considerably between releases 0.9.4 and 0.9.5.

The general drift of the change was to delegate all text rendering to a dedicated rendering controller (currently named RenderingHandler), similar to the collection view rendering. The UI itself keeps layout and positioning of the rendering components. Plus updating on property changes received from the monthView.

Painting: coordinate systems.

• Screen coordinates of months/days, accessible via the getXXBounds() methods. These coordinates are absolute in the system of the monthView.
• The grid of visible months with logical row/column coordinates. The logical coordinates are adjusted to ComponentOrientation.
• The grid of days in a month with logical row/column coordinates. The logical coordinates are adjusted to ComponentOrientation. The columns are the (optional) week header and the days of the week. The rows are the day header and the weeks in a month. The day header shows the localized names of the days and has the row coordinate DAY_HEADER_ROW. It is shown always. The row header shows the week number in the year and has the column coordinate WEEK_HEADER_COLUMN. It is shown only if the showingWeekNumber property is true.

On the road to "zoomable" date range views (Vista-style).

Added support (doesn't do anything yet, zoom-logic must yet be defined) by way of an active calendar header which is added to the monthView if zoomable. It is disabled by default. In this mode, the view is always traversable and shows exactly one calendar. It is orthogonal to the classic mode, that is client code should not be effected in any way as long as the mode is not explicitly enabled.

NOTE to LAF implementors: the active calendar header is very, very, very raw and sure to change without much notice. Better not yet to support it right now.

protected void paintDayOfMonth(Graphics g,
                               Rectangle bounds,
                               Calendar calendar,
                               CalendarState state)

Paints a day which is of the current month with the given state.

PENDING JW: mis-nomer - this is in fact called for rendering any day-related state (including weekOfYear, dayOfWeek headers) and for rendering the month header as well, that is from everywhere. Rename to paintSomethingGeneral. Think about impact for subclasses (what do they really need? feedback please!)

Parameters:

g - the graphics to paint into.

bounds - the rectangle to paint the day into

calendar - the calendar representing the day to paint

state - the calendar state

paintWeekOfYearSeparator

protected void paintWeekOfYearSeparator(Graphics g,
                                        Calendar month)

Parameters:

g - the graphics to paint into

month - the calendar specifying the first day of the month to paint, must not be null

paintDaysOfWeekSeparator

protected void paintDaysOfWeekSeparator(Graphics g,
                                        Calendar month)

Paints the separator between column header (days of week) and days. Note: the given calendar must not be changed.

Parameters:

g - the graphics to paint into

month - the calendar specifying the the first day of the month to paint, must not be null

getWeeks

protected int getWeeks(Calendar month)

Returns the number of weeks to paint in the current month, as represented by the given calendar. The calendar is expected to be set to the first of the month. Note: the given calendar must not be changed.

Parameters:

month - the calendar specifying the the first day of the month to paint, must not be null

Returns:

the number of weeks of this month.

getCalendar

protected Calendar getCalendar()

Returns the monthViews calendar configured to the firstDisplayedDate. NOTE: it's safe to change the calendar state without resetting because it's JXMonthView's responsibility to protect itself.

Returns:

the monthView's calendar, configured with the firstDisplayedDate.

getCalendar

protected Calendar getCalendar(Date date)

Returns the monthViews calendar configured to the given time. NOTE: it's safe to change the calendar state without resetting because it's JXMonthView's responsibility to protect itself.

Parameters:

date - the date to configure the calendar with

Returns:

the monthView's calendar, configured with the given date.

getLastDisplayedDay

public Date getLastDisplayedDay()

Returns the last possible date that can be displayed. This is implemented by the UI since it is in control of layout and may possibly yeild different results based on implementation.

It's up to the UI to keep this property, based on internal state and the firstDisplayed as controlled by the JXMonthView.

Specified by:

getLastDisplayedDay in class MonthViewUI

Returns:

Date The date.

setFirstDisplayedDay

protected void setFirstDisplayedDay(Date firstDisplayedDay)

Updates internal state that depends on the MonthView's firstDisplayedDay property.

Here: updates lastDisplayedDay.

Parameters:

firstDisplayedDay - the firstDisplayedDate to set

getFirstDisplayedDay

protected Date getFirstDisplayedDay()

Returns the first displayed day. Convenience delegate to

Returns:

the firstDisplayed

getFirstDisplayedMonth

protected int getFirstDisplayedMonth()

Returns:

the firstDisplayedMonth

getFirstDisplayedYear

protected int getFirstDisplayedYear()

Returns:

the firstDisplayedYear

getSelection

protected SortedSet<Date> getSelection()

Returns:

the selection

getToday

protected Date getToday()

Returns:

the start of today.

isToday

protected boolean isToday(Date date)

Returns true if the date passed in is the same as today. PENDING JW: really want the exact test?

Parameters:

date - long representing the date you want to compare to today.

Returns:

true if the date passed is the same as today.

updateZoomable

protected void updateZoomable()

Updates state after the monthView's zoomable property has been changed. This implementation adds/removes the header component if zoomable is true/false respectively.

createCalendarHeaderHandler

protected CalendarHeaderHandler createCalendarHeaderHandler()

Creates and returns a calendar header handler which provides and configures a component for use in a zoomable monthView. Subclasses may override to return a custom handler.

This implementation first queries the UIManager for class to use and returns that if available, returns a BasicCalendarHeaderHandler if not.

Returns:

a calendar header handler providing a component for use in zoomable monthView.

getHeaderFromUIManager(), CalendarHeaderHandler, BasicCalendarHeaderHandler

getHeaderFromUIManager

protected CalendarHeaderHandler getHeaderFromUIManager()

Returns a CalendarHeaderHandler looked up in the UIManager. This implementation looks for a String registered with a key of CalendarHeaderHandler.uiControllerID. If found it assumes that the value is the class name of the handler and tries to instantiate the handler.

Returns:

a CalendarHeaderHandler from the UIManager or null if none available or instantiation failed.

setCalendarHeaderHandler

protected void setCalendarHeaderHandler(CalendarHeaderHandler calendarHeaderHandler)

Parameters:

calendarHeaderHandler - the calendarHeaderHandler to set

getCalendarHeaderHandler

protected CalendarHeaderHandler getCalendarHeaderHandler()

Returns:

the calendarHeaderHandler

createDerivedFont

@Deprecated
protected Font createDerivedFont()

Deprecated. KEEP re-added usage in preliminary zoomable support no longer used in paint/layout with renderer.

Create a derived font used to when painting various pieces of the month view component. This method will be called whenever the font on the component is set so a new derived font can be created.
