setPosition calls setValue incorrectly for small sizes. #243
Description
Using your rangeslider with GWT,
The problem we have is at some points, we are doing a resize of panels, and of course, we call update so it will set the new positions.
The update function itself knows the correct value from this.$element[0].value
Finds the correct position it should be in and tells setPosition to move the handle.
The problem comes, that within setPosition, it then tries to do the math from the position, of what the value should be. Here, due to the resizing of the panels, is where things go wrong..
Because the panel is at a small scale at the time, it calculates the value from the position incorrectly (if the number of pixels for the width is smaller than the number of values).
So sets to an incorrect value.. At a width of zero, it actually sets the max value.
Need a way to call setPosition that does nothing more than sets the position of the handler without trying to calculate the value it think's it is at.
I can see why this is doing it, because in the handleMove you do not know what a possible new value could be. But sadly breaks in my scenario.
I am thinking of implementing something along the lines of:
Plugin.prototype.setPosition = function(pos, triggerSlide, value) {
...
// Snapping steps
if ( value === undefined ) {
value = this.getValueFromPosition(this.cap(pos, 0, this.maxHandlePos));
}
...
}And just need to update everywhere that calls setPosition such as
Plugin.prototype.update = function(updateAttributes, triggerSlide) {
...
this.setPosition(this.position, triggerSlide, this.value);
...
}and the change handler
