DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN The MenuShell widget is a custom OverrideShell widget. An OverrideShell widget bypasses mmmmwwwwmmmm when displaying itself. It is designed specifically to contain Popup or Pulldown menu panes. Most application writers never encounter this widget if they use the menu-system convenience functions, XXXXmmmmCCCCrrrreeeeaaaatttteeeePPPPooooppppuuuuppppMMMMeeeennnnuuuu or XXXXmmmmCCCCrrrreeeeaaaatttteeeePPPPuuuullllllllddddoooowwwwnnnn MMMMeeeennnnuuuu, to create a Popup or Pulldown menu pane. The convenience functions automatically create a MenuShell widget as the parent of the menu pane. However, if the convenience functions are not used, the application programmer must create the required MenuShell. In this case, it is important to note that the parent of the MenuShell depends on the type of menu system being built. +o If the MenuShell is for the top-level Popup menu pane, the MenuShell's parent must be the widget from which the Popup menu pane is popped up. +o If the MenuShell is for a menu pane that is pulled down from a Popup or another Pulldown menu pane, the MenuShell's parent must be the Popup or Pulldown menu pane. +o If the MenuShell is for a menu pane that is pulled down from a MenuBar, the MenuShell's parent must be the MenuBar. +o If the MenuShell is for a Pulldown menu pane in an OptionMenu, the MenuShell's parent must be the OptionMenu's parent. Setting XXXXmmmmNNNNhhhheeeeiiiigggghhhhtttt, XXXXmmmmNNNNwwwwiiiiddddtttthhhh, or XXXXmmmmNNNNbbbboooorrrrddddeeeerrrrWWWWiiiiddddtttthhhh for either a MenuShell or its child sets that resource to the same value in both the parent and the child.

For the managed child of a MenuShell, regardless of the value of the shell's XXXXmmmmNNNNaaaalllllllloooowwwwSSSShhhheeeellllllllRRRReeeessssiiiizzzzeeee, setting XXXXmmmmNNNNxxxx or XXXXmmmmNNNNyyyysets the corresponding resource of the parent but does not change the child's position relative to the parent.

The x and y- coordinates of the child's upper left outside corner relative to the parent's upper left inside corner are both 0 (zero) minus the value of XXXXmmmmNNNNbbbboooorrrrddddeeeerrrrWWWWiiiiddddtttthhhh. MenuShell uses the _X_m_Q_T_m_e_n_u_S_y_s_t_e_m trait and holds the _X_m_Q_T_s_p_e_c_i_f_y_R_e_n_d_e_r_T_a_b_l_e trait.
