When using ‘Vertical’, all objects added to the container with no height specified will be laid out with the same height. If you want a control to be a fixed height set its fixedheight property. Same goes for ‘Horizontal’ and fixedwidth.
You can also set ‘spacing’ and ‘margin’ on a container.
Containers can themselves contain containers so, for example, you can add horizontal containers to a vertical container and everything will automatically adjust to the size of the base container e.g. a Form.
When creating a container, you can add a browse in it, very nice. Also you can add commandbuttons in it, this works but you can’t give them properties like height and wide.
Use fixedheight and fixedwidth, e.g.
//.... mybutton2.caption="DoWhatIwant2" mybutton2.fixedheight=26 mybutton2.fixedwidth=60 myform.show(1)
Just to clarify, containers are primarily used in custom sections or apps that are non standard custom apps that are run using the Lianja runtime.
