Changing Custom Control / ALV size in program

Question

Hello,
Everytime I need a screen with more than 1 ALV, I do as follows:
1 - I define one custom container for each ALV;
2 - In my program, I create one object of class CL_GUI_CUSTOM_CONTAINER for each ALV;
3 - For each ALV, I create one object of class CL_GUI_ALV_GRID. For each of these objects, I assign one of the parents created in 2;
So far so good - with this technique I can easily have multiple ALV screens, make ALV's dependent on each other, etc.
My problem is as follows:
- I need to change the screen appearence in my program (typically size and position of the ALV's);
- I tried to use the methods of class CL_GUI_CUSTOM_CONTAINER that seem to be appropriate (SET_HEIGHT, SET_LEFT, etc), but nothing seems to happen:
Example:
CALL METHOD gr_ccontainer1->set_height EXPORTING height = 200.
I would appreciate any help,
Regards,
Joao

Hi Sandra,
Thank you for the tip about the poins, I'll try to correct that, if it is still possible. About the question, I confess that I didn't test the solution with the splitter. Nevertheless, I decided to close the question - I believe that following the tips I'll get somewhere:-)
In fact, trying to resize the ALVs was just a first step towards the final result that I want: to resize the objects in a (ABAP) screen according to the screen resolution. Because time is short I decided not to continue for now, and I used my normal approach:
- Defining a screen for the worst resolution in the project;
- Designing custom containers (that now I know cannot change in size in runtime);
- Attacching my ALVs to these custom containers;
