Change text on progressOn()?

When I use:

dhtmlxLayout.progressOn();

The box always says “Loading…”

Is there a way to customize / translate the text to any string?

The progress bar is a div with background image and “Loading…” is the part of this image. You may redefine the following css class if you want to change it:

div.dhtmlxLayoutPolyProgressBGIMGGlobal_dhx_skyblue {

background-image: url("…/imgs/dhxlayout_dhx_skyblue/dhxlayout_progress_global.gif");

}
