View and objects?

 [1/3] from: g_pizzetta::bluewin::ch at: 3-Oct-2002 23:44


I have a probleme with view. if i make an object including a layout: Essai: make object! [ lay: layout [ text: field "" ]] Essai1: make Essai when i use view/new Essai/lay and view/new Essai1/lay view/new does not display a new windows, and if i try to find a way to do so, the values of the two text field are the same even if they are not part of the saée object. How can I go around this problem?? Thank's a lot. Gilles

so, the values of the two text field are the >same even if they are not part of the saée object. How can I go around this problem?? You must think to essai/lay like a pointer to an object. Make Essai duplicates the pointer, not the object referenced by the pointer. If you duplicate also the object referenced with something like: make essay [lay: make lay] The same problem arises for the object referenced by lay, which surely, being a vid face, has pointers to others objects and so on. A program could find all the references to objects in lay and duplicate them, but it is not a simple solution. For layout objects a more simple solution could be keeping the layout as a block and recalculate it every time: essai: context [layb: [button] lay: layout layb] essai2: make essai [lay: layout layb] --- Ciao Romano

Using 'text as a word for the field there isn't a good idea as layouts already use text.

That should be... Essai1: make Essai []

Use copy on the string in the layout. However, as you've found out, making a copy of Essai like that doesn't make a copy of the layout within the object. The following might be a suitable way around this for you, depending on what you're trying to do... lo: [ txt: field copy "" ] Essai: make object! [ lay: layout lo] Essai1: make Essai [ lay: layout lo] view layout [ button "Essai" [view/new Essai/lay] button "Essai 1" [view/new Essai1/lay] ] HTH. -- Carl Read
