Jscrollpane set vertical scrollbar track height

Question

I'm trying to set a static height of a vertical scrollbar in the jscrollpane library. I have tried settings the track height via CSS and that did not work.

Answer 1

Jscrollpane has a verticalTrackHeight settings variable, but it cannot be set by the user. The only way I've determined to do it is to modify the library slightly:

Within the initialiseVerticalScroll method change the following line from:

verticalTrackHeight = paneHeight;

To:

if(typeof settings.verticalTrackHeight === "number") {
    verticalTrackHeight = settings.verticalTrackHeight;
} else {
    verticalTrackHeight = paneHeight;
}

The height of the vertical track now be set via settings.
