Description

This command allows you to perform a dynamic zoom of the model. When the command is first executed, it waits for the cursor to move into the graphics area. The left mouse button can then be held and dragged in/out to zoom, and the right mouse button can be used to cancel the operation.
Note: Moving the mouse outside of the graphics area will also cancel the operation.

Example

 hwi OpenStack;
    variable t [expr rand()];

    catch {
        hwi GetSessionHandle sess$t;
        sess$t GetProjectHandle proj$t;
        proj$t GetPageHandle page$t [proj$t GetActivePage];
        page$t GetWindowHandle win1$t 1;
        page$t GetWindowHandle win2$t 2;
        win1$t GetViewControlHandle vc1$t;
        vc1$t ScaleView;
    }
    hwi CloseStack;
