Re: align drawing area in vbox or hbox

[yanxin <ycui wmsvision com>]

Here is my source code:

Note: psImage is my struct

  /* Create the raw drawing area. */
  psImage->psDrawingArea = psDrawingArea = gtk_drawing_area_new();
  gtk_drawing_area_size (GTK_DRAWING_AREA(psDrawingArea),
   psImage->iWidthScaled, psImage->iHeightScaled );

  /* Show the image, this routine invokes the 'expose' event and draw the
picture */
  igmain_bImageUpdateForState( psImage, psImage->eImageState );
  gtk_widget_show( psDrawingArea );

  /* Handle the alignment */
  if( psImage->eTextAlignment == align_Left )
  {
   /* Put icon and text into a hbox */
...
  }
  else if( psImage->eTextAlignment == align_Top )
  {
   GtkWidget *align;
   align = gtk_alignment_new (0.5, 0.5, 0, 0);
   /* Put icon and text into a vbox */
   vbox = gtk_vbox_new (FALSE, 0);
   gtk_widget_show( vbox );
   gtk_container_set_border_width (GTK_CONTAINER (vbox), 4);
   if( psImage->pzText )
   {
    label = gtk_label_new (psImage->pzText);
    gtk_widget_show( label );
    gtk_box_pack_start (GTK_BOX (vbox), label, FALSE, FALSE, 0);
    gtk_misc_set_padding (GTK_MISC (label), 10, 0);
   }
   gtk_box_pack_start (GTK_BOX (vbox), align, TRUE, TRUE, 0);
   gtk_container_add (GTK_CONTAINER (align), psDrawingArea);
  }


Thanks
