Create Dynamic Control (G Dataflow)

Version:
Last Modified: August 7, 2018

Creates a control on a panel or tab control at run time. To create a control dynamically at run time, add this control to a G Type and select the G Type in the Data type option on the configuration pane. The G Type cannot be a class.

Programming Patterns

Creating Controls Dynamically on a Panel

connector_pane_image
datatype_icon

parent reference

Reference to a panel or tab control. If you leave this input unwired, the node creates the control dynamically on the panel of the current VI.

datatype_icon

x position

X position, in pixels, of the control to place on the panel or tab control.

Default: 0

datatype_icon

y position

Y position, in pixels, of the control to place on the panel or tab control.

Default: 0

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

control reference

Reference to the control.

You can use this output to change properties of the control. You can also wire this output to the Delete Dynamic Control node to delete the control at run time.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
