How can I access continuously the Screen Reader position? I know that the X and Y variables contain these positions AFTER the Screen Reader exited (QuitProc, EndProc etc.) But I would need the values while the Screen Reader is running.
It is displayed in the Data Display control, but I didn't find the reference where is it written. |

Maybe this is not documented, there is another macro that you can defined called OnTool, which also receive two argument
%1 = tool index, should be 2 for screen reader
%2 = event id, 1 for start of tool, 100 for tracking(dragging) of tool and 0 for end of tool. Tool ID = 0 during tracking, it seems.
X and Y are available during tracking. try this
def OnTool {
type "tool=%1, event=%2, x= $(x), y = $(y)";
};

You are right, pointproc won't give the real time values. But my question is still the same: how can I get them?
It must be possible somehow, because they are displayed in that Data Display control. |

You need to use the PointProc macro. Search the forum for 'PointProc' and 'getpts' and you'll find several examples.
...Even that won't give you real time values. It will only give you the values on click or enter.

The dotoolbox help says the following:
"X, Y -- The X and Y coordinate values of the current cursor position. The values update each time you click the cursor."
So how can I get the cursor position while dragging the Screen Reaser cursor for example? I need the same realtime values as they appear on the Data Display control. |

X and Y are the coordinates at the cursor position. For documentation, look for LabTalk's doToolBox in the programming guide.
