Drag and Drop
For Valikorlia's trading GUI, I'm wanting to implement dragging and dropping. So far, I've gotten dragging down. However, I can't seem to figure out dropping. The "3" is arbitrary; I just copied another NAT's method (which obviously isn't working in this case :D).
This is how I'm doing it. First, we have onRecordSelection(obj), which is just obj.onSelect(). This triggers onDragIcon(obj). (I do it this way to prevent a different icon from being selected when dragging the mouse over it.) From there, a GuiShowImgCtrl is created, which is the floating icon that the user's dragging around. The problem I'm having is detecting when the mouse is over TradeOfferScroll.
PHP Code:
function onDragIcon(obj) {
if(this.dragging) {
return;
}
new GuiShowImgCtrl("TradeInventoryFloater") {
this.width = 32;
this.height = 32;
System.parseimage(this, staticdata.tradeitems[(@ obj).itemid].icon);
this.x = mousescreenx;
this.y = mousescreeny;
}
setTimer(0.05);
}
PHP Code:
function onTimeout() {
if(leftmousebuttonglobal) {
with(TradeInventoryFloater) {
this.x = mousescreenx;
this.y = mousescreeny;
}
this.dragging = true;
setTimer(0.05);
}
else {
if(mousescreenx in |TradeOfferScroll.x, TradeOfferScroll.x + 3|) {
if(mousescreeny in |TradeOfferScroll.y, TradeOfferScroll.y + 3|) {
echo("Added to offer");
}
}
else {
echo("Destroyed");
}
this.dragging = false;
System.destroyobject("TradeInventoryFloater");
setTimer(0);
}
}
Another NAT on Valikorlia suggested using showimg() instead of a GuiShowImgCtrl. Is there any benefit with doing this, as opposed to using a GUI control? |
