Frame setting for widgets

Could someone explain the Frame (left, top, right, bottom) setting for widgets? How are these values decided? I am running into an issue in my plug-in code where two UI controls (TreeViewWidget and StaticTextWidget) overlap over each other.

Explain in the context of the SDK sample WListBoxComposite.sdk

resource WLBCmpNodeWidget (kWLBCmpListElementRsrcID + index_enUS)

{

       __FILE__, __LINE__,

       kWLBCmpListParentWidgetId, kPMRsrcID_None,      // WidgetId, RsrcId

       kBindLeft | kBindRight,                  // Frame binding

       Frame(0, 0, 194, 20),                    // Frame

       kTrue, kTrue,                            // Visible, Enabled

       "",                                                    // Panel name

       {

              WLBCmpEyeballWidget

              (

                     kWLBCmpListElementEyeballWidgetID, kWLBCmpEyeBallIcon, kWLBCmpPluginID, // WidgetId, RsrcId

                     kBindLeft,                                                                        // Frame binding

                    Frame(3,1,22,18)                                                           // Frame

                     kTrue, kTrue,                                                              // Visible, Enabled

                     kADBEIconSuiteButtonType,

              ),

              WLBCmpPenWidget

              (

                     kWLBCmpListElementPenWidgetID, kWLBCmpPenIcon, kWLBCmpPluginID, // WidgetId, RsrcId

                     kBindLeft,                                                                        // Frame binding

                     Frame(25,1,44,18)                                                          // Frame

                     kTrue, kTrue,                                                              // Visible, Enabled

                     kADBEIconSuiteButtonType,

              ),

              // Just a info-static text widget with about-box text view to get white bg.

              WLBCmpTextWidget

              (

                     kWLBCmpTextWidgetID, kPMRsrcID_None,            // WidgetId, RsrcId

                     kBindLeft | kBindRight,                                                    // Frame binding

                    Frame(45,1,194,18)                                                         // Frame

                     kTrue, kTrue, kAlignLeft,kEllipsizeEnd,kTrue,          // Visible, Enabled, ellipsize style, convert ampersands

                     "",                                                                                      // Initial text

                     0,                                                                                       // Associated widget for focus

                     kPaletteWindowSystemScriptFontId,                             // default font

                     kPaletteWindowSystemScriptHiliteFontId,                       // for highlight state.

              ),

       }

};
