      • addJS_addResizeWorkspaceListener

        UIJavaScriptWriter addJS_addResizeWorkspaceListener​(String aFunctionName)
        Adds a JavaScript function to listen for workspace resizing.

        The JavaScript function will be called at the end of the page loading and each time the workspace is resized.

        Two JavaScript Objects parameters are given to the JavaScript function.

        The first Object parameter contains three fields:

        • h: the height of the workspace content region, not including tab titles and not including the bottom bar;
        • w: the width of the workspace content region;
        • vScroll (since 5.9.0): the width of the vertical scroll if it is present, or 0 if there is no scrollbar.

        The second Object parameter has been introduced in 5.9.0, since the workspace displays a translucent form bottom bar in the workspace. The goal is to let the developer choose the zone where the widget will be displayed. It contains four fields:

        • h: the height of the workspace content region, not including tab titles;
        • w: the width of the workspace content region;
        • vScroll: the width of the vertical scroll if it is present, or 0 if there is no scrollbar;
        • hScroll: the height of the horizontal scroll if it is present, or 0 if there is no scrollbar.

        Please note that isPaddingEnabled() from UIFormPane, UserServicePane and UserServiceRawPane are taken into account.

        Example to synchronize the size of an iFrame with the workspace size String jsFnListenerName = "syncIFrameToWorkspace";
        String iFrameId = "myIFrameToSync";

        componentWriter.add("<iframe").addSafeAttribute("id", iFrameId).addSafeAttribute("src", src).addSafeAttribute("style", "border: none").add("/>");

        componentWriter.addJS("function ").addJS(jsFnListenerName).addJS("(size, sizeIncludingBottomBarHeight) {");
        componentWriter.addJS(" var iFrameEl = document.getElementById(\"" + iFrameId + "\");");
        componentWriter.addJS(" iFrameEl.style.height = size.h + \"px\";");
        componentWriter.addJS(" iFrameEl.style.width = size.w + \"px\";");
        componentWriter.addJS("}");

        componentWriter.addJS_addResizeWorkspaceListener(jsFnListenerName);
        Parameters:
        aFunctionName - a JavaScript function name, which will be called when the workspace is resized.
