properties for a front panel object correspond to its position in the front panel window, not on your computer screen.
Setting an object's Position:Top
properties to 0 will typically place it slightly above the visible origin in the front panel window. This is because (0,0)
in the front panel is hidden behind the menu bar and toolbar. Placing an object at (0,43)
will position it at the visible origin. This setting persists when running a VI in a dialog box, so an object at (0,43)
will still appear at the origin. However the origin also persists when you use the scrollbars in the front panel window, so that (0,0)
might not always be the correct origin. Use the FP.Origin
property to obtain the correct origin.
To position an object at the center of your screen, you should use the FP.Origin
properties to calculate the correct center of the front panel window, then use the object's Position:Left
properties to situate it on the center. See the following example of how to do this.
In LabVIEW 7.1 or earlier, refer to the LabVIEW User Manual
for more information about the Position properties. In LabVIEW 8.0 or later, refer to the GObject Properties
topic in the LabVIEW help.
