Have a look at the Autoscale module.
You should also read chapter 8.10.3 AutoScale more advanced examples in the Beginner's Guide.

Best regards.

Klaus - using the AutoScale module may work fine for scaling programmatically added views but then you loose the benefit preview and UI cloud etc.

What I was wondering is whether is it possible to add eg. a Table view using the layout designer or is the only option to use code?

I'm afraid that with the Table class doing it in the code is the only option.

Klaus - If I have some views added in the designer and scripted properly, and then add eg. a Table view in code, in what order should things happen with respect to:

.Loadlayout
ScaleAll(Activity, True)

Also, should I use ScaleAllDS or ScaleAll

If I have some views added in the designer and scripted properly...

Click to expand...

it depends on what you mean with scripted properly.
You should not use AutoScale in the DesignerScripts.
In the Main module you should first load the layout(s) and then scale all views with ScaleAll:
.Loadlayout
ScaleAll(Activity, True)

The difference between ScaleAll and ScaleAllDS.
ScaleAllDS scales with the same equations like AutoScaleAll in the DesignerScripts.
ScaleAll scales with two scale factors one for each direction x and y.
You find a detailed explanation about the difference in chapter 8.10.3 AutoScale more advanced examples in the Beginner's Guide.

Best regards.

Thank you Klaus, your input (as well as the other guys on this forum) is just brilliant.

You say I shouldn't use AutoScale in the DS, should I still use the script for positioning views?
I'm thinking that after I LoadLayout, the views are not scaled (no AutoScale) but are positioned by the script, if I then call scale.ScaleAll surely this will mess with the postioning? By that I mean I would expect to need to do the order as follows:

.Loadlayout
ScaleAll
Reposition all views in code

You are right with this :
.Loadlayout
ScaleAll
Reposition all views in code

Best regards.

I have revisited this again and another question has come up:

When scaling controls added in code, do I add them to the container first (with position/size is already set) and then call ScaleAll? eg.

pnlMain.AddView(txt1, 0, 0, 50dip, 20dip)
ScaleAll
'Surely at this point I would need to reposition again?

What exactly do you want to do ?
Is pnlMain already scaled or not ?
If pnlMain is scaled you should scale only txt1 with ScaleView(txt1) and reposition it afterwards if necessary.
Because if pnlMain is scaled and you call ScaleAll(pnlMain, True) pnlMain will be rescaled and be wrong !

Best regards.
