Hello;

I want to copy an image , I have:
a blind page called 'Parameters" with a image called 'Tag1'
another page with a panel called 'Pan1' and a button with this script:

var v,w;
w = GUI.widget("Pan1");

v = widget("Tag1","Parameters");
w.label="OK";
w.setImage(v.getImage());

Text 'OK' appears, but no image. What is going wrong?
And what is the difference between a 'Widget' and a 'GUI.widget'?


Greetz, Rudy

Try this:

var v,w;
w = GUI.widget("Pan1");

v = CF.widget("Tag1","Parameters");
w.label="OK";
w.setImage(v.getImage());

Both getImage and setImage also take a parameter for the image index so you can track the various image states - see section 3.2.5 in the current manual

There are some things missing:

var v,w;
w = GUI.widget("Pan1");

v = CF.widget("Tag1","Parameters","activity_name");
w.label="OK";
w.setImage(v.getImage(0), 0);

If w is a button you will also need:

w.setImage(v.getImage(1), 1);


w.setImage(v.getImage(0),0); // Released state.
w.setImage(v.getImage(1),1); // Pressed state.

If your button doesn't contain an image for its pressed state for whatever reason there is no need to include, "w.setImage(v.getImage(1),1);" obviously.

This si true.

But i always tend to write the whole code, in case I later decide I want a press state image. It makes it easyer if the code is there, but the graphic is not, than vice-versa.

Hello again;

Tried all your advices, copied the exact code from the manual, tried some things on my own: no succes.

Have made a whole new test-set, so now a have:
- Activity = "Test" with 2 pages:
   - (hidden) Page "RESOURCES" with 2 panels:
         - panel "Tag1" containing a image1
         - panel "Tag2" containing a image2
   - Page "HomeTest" with 1 panel "Pan1"

Plain, simple, straight on, just following the manual.
So, now I put the next script in 'HomeTest'-Page Script:

var w, v;
w = widget("Pan1");
v = widget("Tag1", "RESOURCES","HomeTest");
w.setImage(v.getImage());
widget("w").stretchImage = true;

With this statement: w.setImage(v.getImage(0),0);
or: w.setImage(v.getImage(1),1);
or: w.setImage(v.getImage());
or: v = widget("Tag1", "RESOURCES");
or: v = widget("Tag1", "RESOURCES",HomeTest,"Test");

the debug-page says: TypeError: V has no properties

Well. I'm lost...., gr., Rudy

There are some inconsistencies between your specs and code:

var w, v;
w = widget("Pan1"); <- are you on the page with this widget, as you make a direct call?
v = widget("Tag1", "RESOURCES", "HomeTest"); <- Tag 1 is on the page RESOURCES of the activity "Test", not HomeTest.

The error TypeError: V has no properties means that it can not find whe widget.

The right code is:

var w, v;
w = widget("Pan1");
v = CF.widget("Tag1", "RESOURCES", "Test");
w.setImage(v.getImage(0), 0);
w.stretchImage = true;

If the resource widget is a panel an thus has only one image the call v.getImage(1) is not valid.

To make it more clear next time you can write some more structured code:

var widget1 = widget("Pan1"), // if the widget Pan1 is on the page you're writing the code for
resource_page = CF.page("RESOURCES", "Test"),
resource_widget = resource_page.widget("Tag1");

widget1.setImage(resource_page.widget("Tag1").getImage(0),0):
widget1.stretchImage = true;

Try the following;

- Activity; label = "Test" and tag = "TEST" with 2 pages:
- Page 1; label = "resources", tag = "RESOURCES" with 1 panel:
- panel; label = "Tag1" and tag = "TAG1" containing a image to be copied
- Page 2; label = "HomeTest" and tag = "HOMETEST" with 1 panel;
- panel; label = "Pan1" and tag = "PAN1" containing a image

Script in 'HomeTest'-Page Script:

var w = GUI.widget("PAN1");
var v = CF.widget("TAG1", "RESOURCES");
w.setImage(v.getImage());
w.stretchImage = true;

Note that 'label' refers to text that shows up on button or panel (or in the tree-view if a page or activity). tag refers to the ProntoScript name you assign on the Advanced Tab of the Properties dialog.

O heavenly joy: it works. The problem was that you must put 'CF' in assinging the widget :var v = CF.widget("TAG1", "RESOURCES") since the command 'Widget' is a member of the class 'CF' (or the class 'GUI').

And looking in the manual, indeed it is mentioned (page 87, A.2.2.3. CF.widget() ), but why not a proper example in chapter 3.1.6. 'Changing the image'??

 Thanks all, have a nice Chrismas, gr, Rudy (not the rednosed one).
