The THYStdVCLToolbarController class provides methods for dealing with VCL TToolbar objects. This class is used to establish a connection between the Hydra framework and a specific toolbar component.

Use Case

If you wish to use the VCL TToolbar as your toolbar, you will need to use the THYStdVCLToolbarController component for communication between the toolbar component and the Hydra framework. In order to do so, you have to perform the following steps: * Create an instance of the THYStdVCLToolbarController. * Set the reference to the THYStdVCLToolbarController in your THYModuleManager.ToolbarController property.

Note: You can read about menu and toolbar usage in the Hydra framework in this article. Please also look at the Actions sample shipped with Hydra to see menu and toolbar merging in action.
