Hidedelay on hover

[dencel]

It would be useful to allow a hidedelay on the hovercomponent. This will allow the user to select/click a hovercomponent (like a link to external documentation).

This is a dirty hack to allow this:

isc.Hover.addClassMethods({
    oldShowPtr:isc.Hover.show,
    oldHidePtr:isc.Hover.hide,
    show: function (contents, properties, rect, targetCanvas){
        if(this.hideDelayTimer){
            this.hide(true);
        }
        this.oldShowPtr(contents,properties,rect,targetCanvas);
    },
    hide: function(ignoreDelay){
        var hoverCanvas = isc.Hover.hoverCanvas;
        if(hoverCanvas!=null){
            if(hoverCanvas.hideDelay){
                if(!ignoreDelay){
                    if(!this.hideDelayTimer){
                        this.hideDelayTimer = isc.Hover.delayCall('hide',[true],hoverCanvas.hideDelay);
                    }
                    return;
                }
                if(this.hideDelayTimer) isc.Timer.clear(this.hideDelayTimer);
                delete this.hideDelayTimer;
            }
        }
        this.oldHidePtr();
    }
})

Usage:

isc.ListGrid.create({
 ...
fields:[{
name:'name',headerHoverHTML: function(fieldNum,defaultHtml){
 return isc.Label.create({
   contents: this.getField(fieldNum).documentation,
  hideDelay:3000 // in milliseconds
})
}
}]
})
