Create latch button for instrument panel UI

Since R2024a



hLatchButton = slrealtime.ui.control.LatchButton(hFigure) creates a latch button for an instrument panel uifigure figure. This button downloads the OnValue when the button is pressed by using the computer mouse or other pointing device and retains (latches) this value until the button is again pressed. When the button is released (pressed a second time), the value reverts to the original value from before the first press of the button. You can disable this display by using a button property.

For information about control properties, see slrealtime.ui Properties. If deploying an app, it is important to set the TargetSource property for this control.
