Show the “Customer’s Order” canvas with its horizontal toolbar canvas.

Expand “Canvases.”

 

Save the Form name as version 8.

 

Click on the pb_block canvas either from the layout editor window or the object navigator window.  Then drag the middle handler, to the preferred size.

 

The white line is the border of the "horizontal toolbar canvas."

And the black line is the border of the content canvas.

 

See how it works.  Run the application

 

Notice the window was not sized enough and still you need to resize the window.

Execute the application and navigate through the database records.

Close the application.

 

Drag the black line so the “Customer’s Order” application fits in it.

This is good enough.

 

Run the application.

 

This looks much better.

Execute the query.  Navigate through the application and use all the new push buttons  to test the changes.

 

Add and delete a record.

Close the window and save the changes.

 

Now, you should practice this over and over, until you become a master at it.

Good Luck.
