1. Use a vertical layout
1. Use a vertical layout object for your WINDOW_Layout. 2. LAYOUT_AddChild a layout object with LAYOUT_BevelStyle, BVS_GROUP and LAYOUT_Label, "First Frame" 3. Inside this layout, LAYOUT_AddImage a label image object with the "bla bla" text. 4. End the layout. 5. LAYOUT_AddChild another layout object with LAYOUT_BevelStyle, BVS_GROUP and LAYOUT_Label, "Second Frame". 6. Inside this layout, LAYOUT_AddChild the string gadget. 7. End the layout. The layout hierarchy will be like this: -parent layout (level 1) --child layout (level 2) ---child label image (level 3) --child layout (level 2) ---child string gadget (level 3) Object positioning in ReAction depends on their placement in the layout hierarchy. If the second framed layout is placed after the first one and the parent layout is vertical, the second layout will be positioned at the bottom of the window.

Do something like
Do something like this:
  1. ...
  2.  
  3. WINDOW_Layout, IIntuition->NewObject(LayoutClass, NULL,
  4. LAYOUT_Orientation, LAYOUT_ORIENT_VERT,
  5. LAYOUT_SpaceOuter, TRUE,
  6. LAYOUT_DeferLayout, TRUE,
  7.  
  8. LAYOUT_AddChild, IIntuition->NewObject(LayoutClass, NULL,
  9. LAYOUT_Orientation, LAYOUT_ORIENT_VERT,
  10. LAYOUT_BevelStyle, BVS_GROUP,
  11. LAYOUT_Label, "First Frame"
  12. LAYOUT_AddImage, IIntuition->NewObject(LabelClass, NULL,
  13. LABEL_Text, "Bla bla bla",
  14. TAG_END), // end of the label object
  15. TAG_END), // end of the layout object
  16.  
  17. LAYOUT_AddChild, IIntuition->NewObject(LayoutClass, NULL,
  18. LAYOUT_Orientation, LAYOUT_ORIENT_VERT,
  19. LAYOUT_BevelStyle, BVS_GROUP,
  20. LAYOUT_Label, "Second Frame"
  21. LAYOUT_AddChild, IIntuition->NewObject(StringClass, NULL,
  22. GA_RelVerify, TRUE,
  23. TAG_END), // end of the string object
  24. CHILD_Label, IIntuition->NewObject(LabelClass, NULL, LABEL_Text, "Type text Here:", TAG_END),
  25. TAG_END), // end of the layout object
  26.  
  27. TAG_END), // end of the parent layout object
  28.  
  29. ...
Note that the example code expects that you have obtained the relevant class pointers (LayoutClass, LabelClass, StringClass) before, via OpenClass(). See this tutorial, section 4.2 to learn how to do it.

Thank you both. I will try
Thank you both. I will try as soon as possible. Another things i wants to do is: make the description label on first frame changeable when write something on the StrinObject. I assume that the label should have a name (or ID) and i have to use SetAttr....

In that case, don't LAYOUT_AddImage a label object. Instead, LAYOUT_AddChild a button gadget (or a texteditor gadget, if the string text can get long) object and make it read-only by passing GA_ReadOnly, TRUE.

@AmigaBlitter The structure
@AmigaBlitter The structure looks fine to me - but it won't do exactly what you describe in your first post :-)

@Trixie In the first post is that i want to achieve, while the structure i posted later is one of my some attemps. I'm a little confused by the many methods to do things in OS4. I want to focus on Reaction only, without using Macros (as you seggested).
