ScheduleViewer

Package | flexlib.scheduling
Class | public class ScheduleViewer
Inheritance | ScheduleViewer mx.core.ScrollControlBase

ScheduleViewer is the main scheduling component. It allows you to render and manipulate schedule entries in an efficient and very customizable way. <p><b>ScheduleViewerSample1 - Introduction</b></p> <p> The ScheduleViewerSample1.mxml in the example section shows how to setup a ScheduleViewer with default values and 3 entries. </p> <p> To render schedule entries the dataProvider property by default accepts a collection of flexlib.scheduling.scheduleClasses.IScheduleEntry objects. ScheduleViewerSample1 uses flexlib.scheduling.scheduleClasses.SimpleScheduleEntry, an implementation of IScheduleEntry. </p> <p> The dataProvider item gets passed into the entryRenderer, which by default is flexlib.scheduling.scheduleClasses.renderers.GradientScheduleEntryRenderer.mxml. You can customize various styles of the entry renderer via the entryStyleName style of ScheduleViewer. In ScheduleViewerSample1, we use the default styles but there is an example CSS inlcuded. Try to assign the included myEntryStyle class selector to the entryStyleName style property of the ScheduleViewer instance. </p> <p> In addition, for maximum flexibility, you can provide a fully customized entry renderer via the entryRenderer property. The entryRenderer has to implement flexlib.scheduling.scheduleClasses.renderers.IScheduleEntryRenderer. </p> <p> ScheduleViewer layouts the entries according to the rules of a layout manager. You can specify the layout manager with the entryLayout property. Furthermore, the layout manager can handle any changes that occur to the data provider as any updates, additions, deletions etc to the entries. </p> <p> By default, the flexlib.scheduling.scheduleClasses.layout.BestFitLayout is used, which assigns entries to the top most rows without causing any overlaps between entries. </p> <p><b>ScheduleViewerSample2 - Layout Manager: SimpleLayout</b></p> <p> Another supplied layout manager is the flexlib.scheduling.scheduleClasses.layout.SimpleLayout which places entries exactly as defined in the dataProvider. This means, that when using SimpleLayout, each item of the dataProvider is expected to be of type mx.collection.IList since it represents a row. Each row IList collection is expected to contain IScheduleEntry objects. You can write your own layout manager, check the BestFitLayout and SimpleLayout and their base classes and implemented interfaces for how to do that. </p> <p> The ScheduleViewerSample2.mxml shows how to setup a ScheduleViewer with the supplied SimpleLayout manager. Notice the different structure of the dataProvider, which now exactly determines how entries are being laid out. Furthermore, SimpleLayout does not check entries for overlapping. Therefore, in the second row of ScheduleViewerSample2 you can see one entry overlapping. </p> <p> Notice that we use a different entry renderer in ScheduleViewerSample2. Instead the default gradient renderer we now use flexlib.scheduling.scheduleClasses.renderers.SolidScheduleEntryRenderer </p> <p><b>ScheduleViewerSample3 - Adding Navigation and Zooming</b></p> <p> The ScheduleViewerSample3 sample shows how to add a navigation and a zooming tool. In order to achieve maximum flexibility both features are meant to be driven by external components that talk to an API of ScheduleViewer.</p> <p><i>Zooming</i></p> <p> The ScheduleViewer's zoom property can be manipulated in order to achieve zooming. You could use i.e. a mx:HSlider component that manipulates zoom on each change event as the ScheduleViewerSample3 example shows. A zoom value of 100 always shows the complete dataProvider on the currently visible canvas (no scrollbars have to appear).</p> <p><i>Navigation</i></p> <p> The ScheduleViewer's xPosition and yPosition properties can be manipulated in order to navigate along ScheduleViewer's content. You could use the scroll events of the Timeline component and the pixelScroll events of ScheduleViewer to connect both components and achieve navigation via Timeline. </p> <p> ScheduleViewer offers APIs to navigate (and animate) to specific entries or times. See the gotoNow and gotoSelectedEntry methods of ScheduleViewerSample3. </p> <p> You can select single or multiple entries via the selectedItem and selectedItems property. To switch to the multiple selection mode, set the allowMultipleSelection to true. </p> <p> Furthermore, in this example, the background color of each schedule entry shall be data provider driven. To make this possible, we've specified another supplied entry renderer; flexlib.scheduling.scheduleClasses.renderers.ColoredGradientScheduleEntryRenderer. This enry renderer accepts only flexlib.scheduling.scheduleClasses.ColoredScheduleEntry objects. We've extracted the creation of schedule entries (of type ColoredScheduleEntry) into a separate class. Check out flexlib.scheduling.samples.ScheduleData in the example section below. </p> <p><b>ScheduleViewerSample4 - Adding Background areas</b></p> <p> You can add customized background areas to ScheduleViewer using the backgroundItems property. backgroundItems expects an Array of BackgroundItem objects. You can specify a time range, a color and a description. The latter will be used as a tool tip when the user mouses over area. </p> <p> For further customizations of the background area in ScheduleViewer, you could create your customized version of the background layout manager via the backgroundLayout property. Take a look into the default layout manager flexlib.scheduling.scheduleClasses.layout.BackgroundLayout for more information. i.e. you could add a colored current time area, which moves by the current time. </p> <p> You can also customize the background grid via the supplied styles. See style section. To customize further, you could define custom layout managers via the horizontalLinesLayout and verticalLinesLayout properties. See default implementation is flexlib.scheduling.scheduleClasses.layout.HorizontalLinesLayout and flexlib.scheduling.scheduleClasses.layout.VerticalLinesLayout. i.e. you could add thicker horizontal lines, after certain items.</p> <p><b>ScheduleViewerSample5 - Row based schedulers</b></p> <p> ScheduleViewerSample5 shows how you can synchronize a List control with ScheduleViewer. The pixelScrollEnabled flag lets ScheduleViewer scroll on rows instead of pixels. Animations are still supported for pixels. The itemScroll and pixelScroll events allow to connect external components to ScheduleViewer such as the List shown in this example.</p> <p><b>ScheduleViewerSample6 - Customization of background lines</b></p> <p> ScheduleViewerSample6 shows how you can customize vertical and horizontal background lines with the exposed horizontalLinesViewer and verticalLinesViewer properties of ScheduleViewer. The custom viewers used in this example are flexlib.scheduling.samples.AlternatingHorizontalLinesViewer and flexlib.scheduling.samples.SolidVerticalLinesViewer</p>
