[OpenLayers-Users] Reload Layer

[Arnd Wippermann]

Hi,

Works this also on google layers etc. or only for WMS, WFS? I often got not
all google tiles and to reload the layer, my only idea was to zoom out and
zoom in, but this cause all layers to get their tiles for the new zoomlevel.

function googleRedraw()
{ 
  zoom one level up;
  zoom one level down;
}

Mit freundlichen Grüssen

it may be worthy of mention that this forced redrawing is now supported in
trunk as:

layer.redraw(true);

see definition below:

    /**
     * APIMethod: redraw
     * Redraws the layer.  Returns true if the layer was redrawn, false if
not.
     *
     * Parameters:
     * force - {Boolean} Force redraw by adding random parameter.
     *
     * Returns:
     * {Boolean} The layer was redrawn.
     */
    redraw: function(force) {
        if (force) {
            return this.mergeNewParams({"_olSalt": Math.random()});
        } else {
            return OpenLayers.Layer.prototype.redraw.apply(this, []);
        }
    },
