The ActiveX Component for Tree Diagrams and Tree Views in your Application

VARCHART XTree lets you graphically display, edit and print your data in the form of tree diagrams. VARCHART XTree is the perfect tool to display any kind of hierarchical structure, such as bills of materials, project planning diagrams, work breakdown structures, organigrams or file systems or classifications in general. Not only general tree structures, but also specific styles such as the look of the Microsoft Explorer can be displayed (TreeView Style).

New!

Dynamical objects:

The following objects can be created, edited and deleted dynamically now:

• Node appearances (VcNodeAppearance)
• Node formats (VcNodeFormat)
• Filters (VcFilter)

Until now, all properties of these objects could be changed only at design time. Now they also can be changed and saved at runtime. The objects created dynamically also can be made persistent.

New Event OnShowInPlaceEditor
The new event OnShowInPlaceEditor occurs, if you click onto a marked node field. You can use it to call an editor of your own instead of the pre-installed Edit Control. So you can facilitate your customers to edit dates comfortably with the help of a date picker.

Border Areas
The possibilities of the border areas of the diagram have been extended: Three areas above and six areas beneath the diagram are available now. Each of them may contain texts, graphics or a legend.

Event OnModifyComplete
The event OnModifyComplete always occurs, if any data have been edited interactively, e.g. if nodes or links have been created or deleted, if boxes have been edited, etc. With the help of this event you can set a tag that will remind you that the data must be saved before closing the program.

• The possibilities to navigate in the diagrams with the help of the Num area of the keyboard have been improved.
• With the help of the VcPrinter property RepeatTitleAndLegend you can specify whether the title and the legend will be repeated on each side and whether nodes will be split, if the dia-gram is split to several pages.
• The properties ScrollOffsetX and ScrollOffsetY let you save the current scroll offset in x direction of the diagram section currently dis-played and set it again if the same application is started.
• The Error event occurs when an unforeseen error is found in the code of VARCHART XTree. With the help of this event you can take down the errors that occur at the customers comforta-bly, e.g. in a file.
