layout - Can Java SWT GridLayout lay out widgets from right to left? -

from api document of gridlayout: "widgets laid out in columns left right,...", i'm wondering if there someway lay out widgets right left? or, when have 1 column applies gridlayout, can lay out widgets bottom top? (sorry poor english!)

the magic word here swt.right_to_left. however, not applied layout, composite containing widgets.

here example code:

public static void main(string[] args) {     final display display = new display();     shell shell = new shell(display);     shell.setlayout(new gridlayout(2, true));     shell.settext("expandbar example");      composite ltr = new composite(shell, swt.left_to_right);     ltr.setlayout(new gridlayout(3, true));     ltr.setlayoutdata(new griddata(swt.fill, swt.fill, true, true));     composite rtl = new composite(shell, swt.right_to_left);     rtl.setlayout(new gridlayout(3, true));     rtl.setlayoutdata(new griddata(swt.fill, swt.fill, true, true));      for(int = 0; < 10; i++)     {         new button(ltr, swt.push).settext("button " + i);         new button(rtl, swt.push).settext("button " + i);     }      shell.pack();     shell.open();      while (!shell.isdisposed())     {         if (!display.readanddispatch())         {             display.sleep();         }     }     display.dispose(); } 

and looks like:

to both right-to-left , bottom-to-top, you'll have use moveabove/movebelow null parameter:

public static void main(string[] args) {     final display display = new display();     shell shell = new shell(display);     shell.setlayout(new gridlayout(2, true));     shell.settext("stackoverflow");      composite ltr = new composite(shell, swt.left_to_right);     ltr.setlayout(new gridlayout(3, true));     ltr.setlayoutdata(new griddata(swt.fill, swt.fill, true, true));     composite rtl = new composite(shell, swt.left_to_right);     rtl.setlayout(new gridlayout(3, true));     rtl.setlayoutdata(new griddata(swt.fill, swt.fill, true, true));      int nrofitems = 10;     int nrofcolumns = ((gridlayout) rtl.getlayout()).numcolumns;     int filleritems = nrofcolumns - nrofitems % nrofcolumns;      (int = 0; < nrofitems; i++)     {         new button(ltr, swt.push).settext("button " + i);         new button(rtl, swt.push).settext("button " + i);     }      for(int = 0; < filleritems; i++)         new label(rtl, swt.none);      control[] children = rtl.getchildren();     (int = 0; < children.length; i++)     {         children[i].moveabove(null);     }      shell.pack();     shell.open();      while (!shell.isdisposed())     {         if (!display.readanddispatch())         {             display.sleep();         }     }     display.dispose(); } 

looks this:
