List of XULRunner Issues Related to Visual Page Editor

Version 5

    Known problems in XULRunner 1.9.2

    org.mozilla.interfaces.inIFlasher

    inIFlasher does not work on MacOS. It is needed to show a border around selected elements in VPE.

    Workaround: To show a border on MacOS the following style is used: "border: 2px solid COLOR_NAME !important". But the workaround has a drawback: if the selected elements has its own border, it is not visible.

    draggesture event

    XULRunner does not fire 'draggesture' event on Linux.

    Workaround: Special button for Drag&Drop actions is used. Instead of listening to the 'draggesture' events, VPE listens to the 'mousedown' event on this button.

    org.mozilla.interfaces.nsIDragService.invokeDragSession(...)

    The method invokeDragSession works differently on Windows and Linux. On Windows it exits after the session is ended. On Linux it exits immediately. The following snippet illustrates this:

     

    document.addEventListener("dragstart", new nsIDOMEventListener() {
         nsISupports queryInterface(String uuid) {
              return null;
         }
         void handleEvent(nsIDOMEvent event) {
              nsIDragService dragService = (nsIDragService)
                    Mozilla.getInstance().getServiceManager()
                             .getServiceByContractID("@mozilla.org/widget/dragservice;1",
                                       nsIDragService.NS_IDRAGSERVICE_IID);
              System.out.println("BEFORE invokeDragSession");
              dragService.invokeDragSession(node, transferables, null,
                    nsIDragService.DRAGDROP_ACTION_MOVE
                            | nsIDragService.DRAGDROP_ACTION_COPY
                            | nsIDragService.DRAGDROP_ACTION_LINK);
              System.out.println("AFTER invokeDragSession");
         }
    }, false);
    document.addEventListener("dragend", new nsIDOMEventListener() {
         nsISupports queryInterface(String uuid) {
              return null;
         }
         void handleEvent(nsIDOMEvent event) {
              System.out.println("dragend");
         }
    }, false);
    document.addEventListener("dragover", new nsIDOMEventListener() {
         nsISupports queryInterface(String uuid) {
              return null;
         }
         void handleEvent(nsIDOMEvent event) {
              System.out.println("dragover");
         }
    }, false);
    

         Windows output:

    BEFORE invokeDragSession

    dragover

    dragover

    ...

    dragover

    dragend
    AFTER invokeDragSession

         Linux output:

    BEFORE invokeDragSession
    AFTER invokeDragSession

    dragover
    dragover
    ...
    dragover

    dragend
