snap to edges

[mrsingh816]

??? How could I make my application snap to screen edges (like winamp)?

[SWFKit]

/* snap to the border if within the distance */
var distance = 50;
var snapInterval, direct;
/* if the app is snaping to the screen border*/
var moving = false;

/* move the window to the screen border */
function snapTo(direct)
{
var wnd = getMainWnd();
var reach = false;/* reach the border of the screen? */

switch (direct)
{
case 0: /* left */
if (wnd.left > 0) 
wnd.move(wnd.left - 1, wnd.top, wnd.left + wnd.width - 1,
 wnd.top + wnd.height);
if (wnd.left == 0) reach = true;
break;

case 1:/* top */
if (wnd.top > 0) 
wnd.move(wnd.left, wnd.top - 1, wnd.left + wnd.width,
 wnd.top + wnd.height - 1);
if (wnd.top == 0) reach = true;
break;

case 2: /* right */
if (wnd.left + wnd.width < SysInfo.workareaRight) 
wnd.move(wnd.left + 1, wnd.top, wnd.left + wnd.width + 1,
 wnd.top + wnd.height);
if (wnd.left + wnd.width == SysInfo.workareaRight) reach = true;
break;

case 3: /* bottom */
if (wnd.top + wnd.height < SysInfo.workareaBottom) 
wnd.move(wnd.left, wnd.top + 1, wnd.left + wnd.width,
 wnd.top + wnd.height + 1);
if (wnd.top + wnd.height == SysInfo.workareaBottom) reach = true;
break;
}

if (reach)
{
/* reach the border, stop moving */
Application.clearInterval(snapInterval);
moving = false;
}
}

/* 
handle the WM_ONEXITSIZEMOVE to see if 
we need to snap the app to the screen border  
*/
getMainWnd().onExitSizeMove = function ()
{
/* Is the app snaping to screen border? */
if (moving) return;

direct = -1;

// left
if (this.left > 0 && this.left <= distance) direct = 0;
// top
else if (this.top > 0 && this.top <= distance) direct = 1;
//right
else if (this.left < SysInfo.workareaRight - this.width && 
this.left >= SysInfo.workareaRight - this.width - distance)
direct = 2;
//bottom
else if (this.top < SysInfo.workareaBottom - this.height &&
this.top >= SysInfo.workareaBottom - this.height - distance)
direct = 3;

if (direct >= 0)
{
// Move the window
snapInterval = Application.setInterval(snapTo, 10, direct);
moving = true;
}
}

Hey, thank you sooooooo much for the code!!!

Is this suppose to be inserted into the "initialize" script?? if not where and how is this script activated?

thanks for you help.

[SWFKit]

Yes, insert it into the "initialize" script.

[mrsingh816]

i did that and it doesnt work. By the way, I'm using transparent swf with custom shape (its rectangle, nothing overly complex) with no application borders.

[SWFKit]

A sample and the exe file.

The sample requires swfkit or swfkit pro.

[SWFKit]

Sorry, it doesn't support a window moved by dragging the client area of the window([Operation Panel]->[Application definition]->[Interaction]->[Left mouse button click]). The mechanism of the "Drag window" feature of the left mouse click in swfkit is different from that of moving window by dragging the title bar of the window. It doesn't send the wm_exitsizemove event at all.

We will send the WM_EXITSIZEMOVE message in the next version.

Ok. no problem. Thanks for all your help. I was hoping to have that feature as a convenience, but i can do without it.

Thanks
