LabVIEW Determines the position of the control in the display coordinate system

Want to know one VI The location of the control in the , But when using the location property of the control , Associated with it is LabVIEW origin , Instead of the display origin . How to determine the position of the control in the display coordinate system .

answer :  The position of the front panel object is relative LabVIEW In terms of coordinate system , The position it gives is related to the origin of the front panel . The crosshairs deepened on the front panel in edit mode are LabVIEW Origin of coordinate system .

In order to determine the position of the control in the display coordinate system , Users also need to use some other attribute nodes . The required properties are LabVIEW 8 Different from later versions . according to LabVIEW Choose a different usage for the version of .

LabVIEW7.1  And earlier

By subtracting the origin attribute value of the front panel from the boundary of the front panel, the user can LabVIEW Convert coordinates to display coordinates , As shown in the figure below . It gives... In the display coordinate system LabVIEW origin . For specific methods, see... In the annex Getting Screen Coordinates Example VI.

​

LabVIEW8.x  And later versions

The implementation method of the later version is very similar to that of the previous version , It's just that the origin attribute is no longer used . Instead, the origin attribute of the front panel pane , As shown in the figure below . Specific example programs are included in the attachment Getting Screen Coordinates 8x VI in .
