LabVIEW
A bundle of simple questions. (displaycircle, empty background, control the visible of cursor, etc)
Hi,
I need to draw a simple circle on an empty background, and I need to record the cursor position during the movement . However, my cursor will only appear for a period and then turn off.
So, the task is going to be divided into a few steps.
1. make an empty full screen background
2. draw a circle on the background (in pixel)
3. record the cursor position (in pixel)
4. control the "visualibilty" of the cursor
I am following an example called Panel to Graph Coords.vi. It seems that I can make an empty background, but I have no clue how to make it to be full screen in labview 7.0. The cursor position in that vi, I believe, is a relative position. However, I want to absolute one. I know how to draw a circle in XY graph, but I have no clue how to draw it in the extact pixel (I mean the circle has to be in the fixed position of the screen, with the same unit of the cursor position). The last thing is that I don't know how to turn the cursor off. I have already tried the property node to control turn off the visible, but it does not work.
Do you have any suggestion? Can I not use xy graph?
thanks
