move pane by mouse

[Brian001]

i want to use mouse to move pane, by registering three events: mouse down?, mouse move, and mouse up

in mouse down? handler: i get the current mouse coordinate and register pane mouse move event.

in mouse up handler: i unregister pane mouse move event.

in mouse move handler: i calculate the distance of mouse, then change the origin of pane.

throught this way, i can move pane, but it is not nice, the move is not smooth as i expected, i try several times, still same?

any suggestion?

Thanks

Hi

Your idea is not that bad. What you could do to improve, is just to move the pane after the mouse up event. Instead of moving the pane in each mouse move event, you could calculate dx and dy.

Hi becktho,

I've just been trying this one.  Any chance you could back-save it to LV 7.1?

[becktho]

No problem. Here you are...

i get it, thank you so much.

by the way, do you know whether it is the same way in vc++

[CharlieRodway]

Hi Becktho,

Thanks - although LV didn't like it. I guess it's probably down to the fact that panes aren't in LV7.1

[becktho]

Yes you're right - didn't think about that.

But basically you should be able to do it the same way by setting the panel origin.

If it is the same in VC++ I can't tell you. The basic idea should be useable there as well.

hi becktho

i create a vi without menu, window title, toolbar. i resize the window to fit a control. refer to the following vi, how can i move it smoothly using mouse event?

thanks

Hmm - two brians with the same type of task. Seems to be some school exercise.

Well brian005 - you can look at the other answers. I don't want to post the same thing twice.

it is different, in this case, you cannot get mouse event over pane, instead, get mouse event over the control, the difference between control and pane is: you always can get mouse up event of pane, but for control, you always lost the mouse up event, because the mouse move out the control, so the way should be different.

you can try the following vi

any suggestion?

thanks for reply
