TabTree allows you to add a Sheet-Management control to a window. It creates a list of all the tabs in a list box. You can then navigate between tabs using either the keyboard or mouse and the list itself.

This approach is especially useful on windows where the sheet control contains many tabs, so many that the sheet control "overflows". It's also very useful on windows where you have Sheet Controls on another tab. By presenting the tab list as a tree, the layout of the window becomes a lot simpler.

• User friendly and modern looking tab selection.
• Handles nested Sheet controls (i.e. sheets on tabs).
• Allows you to set the Sheet as Wizard and/or NoSheet at runtime - thus making design easier.
• Tree selection matches tab selection (where tabs are programmatically selected).
• Multiple TabTree controls on each window.
• Automatically scans all the Sheet and Tab properties and builds the list appropriately.
• Supports Single EXE and Multi-DLL.

1. Open your application in the Clarion IDE.
2. Add the Activate CapeSoft TabTree Global Extension template to your application. To do this, Click on Global, then Extensions, then Insert, scroll down to the Class TabTree templates and double-click on the Activate CapeSoft TabTree template.
3. Now open the window containing a sheet that you want to replace with the TabTree list, and proceed to the window formatter.
4. Make some space in your window for the TabTree list box (usually on the left).
5. Place the TabTree control template on your window. To do this, from the Populate menu, select Control Template... and select the SimTree control template from the Class SimTabTreeControl items. You don't need to select a Queue in the From field - and if Clarion prompts you for one, simply click the cancel button.

If you are adding this to a MultiDLL application, then follow the steps in the Multi-DLL section of this document.

• Global Extension Template
• TabTree Control Template

The Global Extension Template

TabTree Control Template

In your Data-DLL:

• Add the TabTree Global Extension template
• On the Multi-DLL Tab turn on both options..

In your other applications (that require the use of TabTree in that application) including DLL's and EXE's:

• Add the TabTree Global Extension template
• On the Multi-DLL Tab turn on ONLY the first option.

Runtime Problems

• I have a contract box on my root - but it won't contract the list?

Feature Questions

• How do I change the icons?
• How do I Hand Code TabTree, do you support hand coding without templates?

Upgrading Issues

• How much does it cost to update to the latest version of TabTree from previous versions?
• How do I upgrade from SimTabTree to TabTree?

1.1) I have a contract box on my root - but it won't contract the list?

This is unfortunately a limitation of Clarion (as of writing - C6 9058). You will need to switch to using a root (see the template section) which will not have the contract box.

2.1) How do I change the icons?

In the Global extension you can choose which icons to use for the tree. At the local level you can override the icons for any one TabTree control.

2.2) How do I Hand Code TabTree, do you support hand coding without templates?

TabTree, like almost all of our products, is straight forward to hand code. We recommend using the template as a "quick start" for hand coding, as they generate the project and basic code for you:

• Create a new empty application. This can be ABC or Legacy.
• Add the TabTree global extension, and add a window with one or more Tab controls (you can import a window from an actual application, which can be helpful).
• Add the TabTree local extension.
• Generate the application

This provides you with the basic code that you need to use TabTree, and you can export the Project file from the application in order to see what needs to be added to your Project. This approach in very helpful for using any of the CapeSoft templates in a hand coded application, and allows you to use the templates and generator to build the basic code for you. The code can then be copied and pasted into your hand coded applications and modified as needed.

3.1) How much does it cost to update to the latest version of TabTree from previous versions?

It is CapeSoft's policy not to charge for updates for as long as we can, so typically you can upgrade to the latest release of TabTree from any previous version for free. Visit the CapeSoft web site at www.capesoft.com to get the latest version.

3.2) How do I upgrade from SimTabTree to TabTree?

You must only add the TabTree global extension to your application. The other settings will remain consistent from the SimTabTree local extension template.
