CalendarPicker

A CalendarPicker is a rectangular input for picking a date or a range of dates on a calendar viewer.

The current value is an Interval of dates. Please note that the interval is non-inclusive, that is, the end day is one day after the final date the user selected.

If the user only selected one date, start will be the selection and end is the day after.

class CalendarPicker : Widget {

this(Widget parent);

Interval!Date value();

void value(Interval!Date v);

}

value Interval!Date value(): Current value the user selected. Please note this is NOT valid until AFTER a change event is emitted.
value void value(Interval!Date v): Sets a new interval. Remember, the end date of the interval is NOT included. You might want to end + 1.days when creating it.

enabled bool enabled [@property getter]
bool enabled [@property setter]: Determines whether the control is marked enabled. Disabled controls are generally displayed as greyed out and clicking on them does nothing. It is also possible for a control to be disabled because its parent is disabled, in which case this will still return true, but setting enabled = true may have no effect. Check disabledBy to see which parent caused it to be disabled.
disabledReason string disabledReason [@property getter]
string disabledReason [@property setter]: If the widget is not enabled this string may be presented to the user when they try to use it. The exact manner and time it gets displayed is up to the implementation of the control.
disabledBy Widget disabledBy(): Returns the widget that disabled this. It might be this or one of its parents all the way up the chain, or null if the widget is not disabled by anything. You can check disabledReason on the return value (after the null check!) to get a hint to display to the user.
setPropertyFromString SetPropertyResult setPropertyFromString(string name, const(char)[] value, bool valueIsJson)
getPropertiesList void getPropertiesList(void delegate(string name) sink)
getPropertyAsString void getPropertyAsString(string name, void delegate(string name, scope const(char)[] value, bool valueIsJson) sink): Implementations of ReflectableProperties interface. See the interface for details.
scaleWithDpi int scaleWithDpi(int value, int assumedDpi)
Point scaleWithDpi(Point value, int assumedDpi): Scales the given value to the system-reported DPI for the monitor on which the widget resides.
currentDpi int currentDpi(int assumedDpi): Returns the current scaling factor as a logical dpi value for this widget. Generally speaking, this divided by 96 gives you the user scaling factor.
defaultTextHeight int defaultTextHeight(int numberOfLines)
encapsulatedChildren bool encapsulatedChildren(): If encapsulatedChildren returns true, it changes the event handling mechanism to act as if events from the child widgets are actually targeted on this widget.
dpiChanged void dpiChanged(): Virtual hook to update any caches or fonts you need on the event of a dpi scaling change.
widthShrinkiness int widthShrinkiness()
heightShrinkiness int heightShrinkiness(): Where stretchiness will grow from the flex basis, this shrinkiness will let it get smaller if needed to make room for other items.
flexBasisWidth int flexBasisWidth()
flexBasisHeight int flexBasisHeight(): The initial size of the widget for layout calculations. Default is 0.
defaultMargin Rectangle defaultMargin;
defaultPadding Rectangle defaultPadding;: Not stable.
styleTagName string styleTagName(): Returns the style's tag name string this object uses.
ClassList struct ClassList: API for the styleClassList
styleClassList inout(ClassList) styleClassList(): Returns a "class list" that can be used by the visual theme's style engine via VisualTheme.getPropertyString if it chooses to do something like CSS.
DynamicState enum DynamicState
dynamicState ulong dynamicState [@property getter]
ulong dynamicState [@property setter]
setDynamicState void setDynamicState(ulong flags, bool state): List of dynamic states made available to the style engine, for cases like CSS pseudo-classes and also used by default paint methods. It is stored in a 64 bit variable attached to the widget that you can update. The style cache is aware of the fact that these can frequently change.
Style class Style: Style properties are defined as an accessory class so they can be referenced and overridden independently, but they are nested so you can refer to them easily by name (e.g. generic Widget.Style vs Button.Style and such).
OverrideStyle mixintemplate OverrideStyle(S...): This mixin overrides the useStyleProperties method to direct it toward your own style class. The basic usage is simple:
useStyleProperties void useStyleProperties(void delegate(scope Style props) dg): You can override this by hand, or use the OverrideStyle helper which is a bit less verbose.
removeWidget void removeWidget(): Removes this widget from its parent.
widgetRemoved void widgetRemoved(size_t oldIndex, Widget oldReference): Notifies the subclass that a widget was removed. If you keep auxillary data about your children, you can override this to help keep that data in sync.
removeAllChildren void removeAllChildren(): Removes all child widgets from this. You should not use the removed widgets again.
getChildByName Widget getChildByName(string name): Calls getByName with the generic type of Widget. Meant for script interop where instantiating a template is impossible.
getByName WidgetClass getByName(string name): Finds the nearest descendant with the requested type and name. May return this.
name string name;: The name is a string tag that is used to reference the widget from scripts, gui loaders, declarative ui templates, etc. Similar to a HTML id attribute. Names should be unique in a window.
defaultEventHandlers EventHandler[string] defaultEventHandlers;
setupDefaultEventHandlers void setupDefaultEventHandlers()
defaultEventHandler_click void defaultEventHandler_click(ClickEvent event)
defaultEventHandler_dblclick void defaultEventHandler_dblclick(DoubleClickEvent event)

defaultEventHandler_focus void defaultEventHandler_focus(Event event)
defaultEventHandler_blur void defaultEventHandler_blur(Event event)
defaultEventHandler_focusin void defaultEventHandler_focusin(Event event)
defaultEventHandler_focusout void defaultEventHandler_focusout(Event event): Default event handlers. These are called on the appropriate event unless Event.preventDefault is called on the event at some point through the bubbling process.
addDirectEventListener EventListener addDirectEventListener(string event, void delegate() handler, bool useCapture)
EventListener addDirectEventListener(string event, void delegate(Event) handler, bool useCapture)
EventListener addDirectEventListener(Handler handler, bool useCapture)
addEventListener EventListener addEventListener(string event, void delegate() handler, bool useCapture)
EventListener addEventListener(Handler handler, bool useCapture)
EventListener addEventListener(string event, void delegate(Event) handler, bool useCapture)
EventListener addEventListener(string event, EventHandler handler, bool useCapture)
removeEventListener void removeEventListener(string event, EventHandler handler, bool useCapture)
void removeEventListener(EventListener listener): Events use a Javascript-esque model. See more details on the Event page.
globalCoordinates Point globalCoordinates(): Returns the coordinates of this widget on the screen, relative to the upper left corner of the whole screen.
handleWmCommand void handleWmCommand(ushort cmd, ushort id): Called when a WM_COMMAND is sent to the associated hwnd.
handleWmNotify int handleWmNotify(NMHDR* hdr, int code, int mustReturn): Called when a WM_NOTIFY is sent to the associated hwnd.
statusTip string statusTip;: This tip is displayed in the status bar (if there is one in the containing window) when the mouse moves over this widget.
tabStop bool tabStop;: If true, this widget can be focused via keyboard control with the tab key.
tabOrder int tabOrder;: The tab key cycles through widgets by the order of a.tabOrder < b.tabOrder. If they are equal, it does them in child order (which is typically the order they were added to the widget.)
hwnd HWND hwnd;: The native handle, if there is one.
x int x;
y int y;: Child's position relative to the parent's origin. only the layout manager should be modifying this and even reading it is of limited utility. It may be made private at some point in the future without advance notice. Do NOT depend on it being available unless you are writing a layout manager.
parentWindow inout(Window) parentWindow [@property getter]: Returns the window to which this widget is attached.
newParentWindow void newParentWindow(Window oldParent, Window newParent): Called when the widget has been added to or remove from a parent window.
children inout(Widget)[] children [@property getter]: Returns the list of the widget's children.
parent inout(Widget) parent [@property getter]: Returns the widget's parent.
width int width [@property getter]
height int height [@property getter]: The widget's current size.
width int width [@property setter]
height int height [@property setter]: Only the layout manager should be calling these.
registerMovement void registerMovement(): This function is called by the layout engine after it has updated the position (in variables x and y) and the size (in properties width and height) to give you a chance to update the actual position of the native child window (if there is one) or whatever.
isFocused bool isFocused(): Returns true if this is the current focused widget inside the parent window. Please note it may return true when the window itself is unfocused. In that case, it indicates this widget will receive focuse again when the window does.
showing bool showing()
hidden bool hidden()
showing void showing(bool s, bool recalculate): Shows or hides the window. Meant to be assigned as a property. If recalculate is true (the default), it recalculates the layout of the parent widget to use the space this widget being hidden frees up or make space for this widget to appear again.
show void show(): Convenience method for showing = true
hide void hide(): Convenience method for showing = false
showOrHideIfNativeWindow bool showOrHideIfNativeWindow(bool shouldShow): If you are a native window, show/hide it based on shouldShow and return true.
focus void focus()
attachedToWindow void attachedToWindow(Window w): This is called when the widget is added to a window. It gives you a chance to set up event hooks.
addedTo void addedTo(Widget w): Callback when the widget is added to another widget.
addChild void addChild(Widget w, int position): Adds a child to the given position. This is protected because you generally shouldn't be calling this directly. Instead, construct widgets with the parent directly.
getChildAtPosition Widget getChildAtPosition(int x, int y): Finds the child at the top of the z-order at the given coordinates (relative to the this widget's origin), or null if none are found.
addScrollPosition void addScrollPosition(int x, int y): If the widget is a scrollable container, this should add the current scroll position to the given coordinates so the mouse events can be dispatched correctly.
paint void paint(WidgetPainter painter): Responsible for actually painting the widget to the screen. The clip rectangle and coordinate translation in the WidgetPainter are pre-configured so you can draw independently.
paintContent Rectangle paintContent(WidgetPainter painter, Rectangle bounds): Responsible for drawing the content as the theme engine is responsible for other elements.
erase void erase(WidgetPainter painter): I don't actually like the name of this this draws a background on it
draw WidgetPainter draw()
privatePaint void privatePaint(WidgetPainter painter, int lox, int loy, Rectangle containment, bool force, bool invalidate): This can be overridden by scroll things. It is responsible for actually calling paint. Do not override unless you've studied minigui.d's source code. There are no stability guarantees if you do override this; it can (and likely will) break without notice.
redraw void redraw(string file, size_t line)
emit bool emit(Args args)
bool emit(): Allows a class to easily dispatch its own statically-declared event (see Emits). The main benefit of using this over constructing an event yourself is simply that you ensure you haven't sent something you haven't documented you can send.
subscribe EventListener subscribe(void delegate(EventType) handler): Does the same as addEventListener's delegate overload, but adds an additional check to ensure the event you are subscribing to is actually emitted by the static type you are using. Since it works on static types, if you have a generic Widget, this can only subscribe to events declared as Emits inside Widget itself, not any child classes nor any child elements. If this is too restrictive, simply use addEventListener instead.
getComputedStyle StyleInformation getComputedStyle(): Gets the computed style properties from the visual theme.
borderBoxForContentBox Rectangle borderBoxForContentBox(Rectangle contentBox): Calculates the border box (that is, the full width/height of the widget, from border edge to border edge) for the given content box (the area between the padding)
