Description

The CurrentTool is the tool used to interact will the SceneControl's display. Always check if a tool is enabled before setting it to the CurrentTool property, otherwise a user will be able to use a tool that is actually disabled.

Errors Returned

1004 800a03ec: Current tool will not deactivate

Remarks

When the CurrentTool is set the following events occur:

1. The ITool::Deactivate event is triggered on the 'old' CurrentTool if one was set. If this event returns false a trappable error ocurrs. If this event returns true the 'old' CurrentTool is removed and replaced.
2. The ICommand::OnClick event is triggered on the 'new' CurrentTool and its cursor is picked up.

Within an ITool implementation it is recommended that the ITool::Deactivate event returns true. This allows a 'new' CurrentTool to be set, and allows the release of the CurrentTool when an application is shutting down.

ICommand command=new ControlsSceneZoomInOutToolClass();
command.OnCreate(axSceneControl1.Object);
if (command.Enabled == true)
{
  axSceneControl1.CurrentTool= (ITool) command;
}

Dim pCommand As ICommand
pCommand=New ControlsSceneZoomInOutToolClass
pCommand.OnCreate(AxSceneControl1.Object)
If pCommand.Enabled=True Then
  AxSceneControl1.CurrentTool=pCommand
End If
