Summary: DOUG provided mouse coordinates not reliable

Created: 2012–03–26 10:48

Status: Released

Category: Bug

From: frankie

Version: 2.2

Released_In: 2.4

Description:

There are two tcl variables, ${doug.mousex} and ${doug.mousey} that are updated on mouse motion events. Some tcl scripts and plugins use the variables to detect where the cursor is on certain events.

The issue is that there are cases where these are unreliable. The following code can be pasted in the console to demonstrate the issue:

bind [doug.display get -ogl_window] <Button-1> { 
    set tk_mousex [expr [winfo pointerx $oglwin] - [winfo rootx $oglwin]]; 
    set tk_mousey [expr [winfo pointery $oglwin] - [winfo rooty $oglwin]];
    puts "DOUG Mouse XY: ${doug.mousex} ${doug.mousey}  vs Tk: $tk_mousex $tk_mousey"
}

now, clicking on the DOUG window, you will get printouts that show the differences. Multiple clicks without moving the mouse should show the x coordinate increasing when it shouldn't be.

Also, when running on a machine where the DOUG window doesn't grab focus (such as on the Mac version), the very first mouse click can be off as no motion event has happened to cause it to update.

Also, it looks like doug.tcl was also binding on the click and incrementing the doug.mousex variable directly. This might fix that by overwriting the change, but that script still needs to be updated. @] |
