how to arm a timer

Posted by arealnewbie (arealnewbie), 2 August 2004

hi I want to make a script (for a binding) that make a window appear when the user let the mouse on an item long enought (like a tool tip ) and I haven't find how to empeach the window to appear if the mouse leave the item before the timer ends (I can't cancel the "good" timer)
Code:

$ecranRadar bind mytag <Enter> "after $timer setwindow $canvas %x %y"
$ecranRadar bind mytag <Leave> "after cancel #??#"

Posted by admin (Graham Ellis), 3 August 2004

Set the timer ... and when it completes run a command which checks some other variable and EITHER pops up our new window OR does nothing further depending on the value of that variable. Then all you have to do is to iniialse that variable to your "I wanna window" value and change it to the "I don't wanna window value" in your other event handlers.

Hopefully this is something where the explanation is much bigger than the code
