Hi,
I have a problem with drag&drop. The following example is based on the
SUDragDropTest.
There are several list items on which i can drop and from which i can
drag the objects.
Everything goes fine for some drag and drops, but after the second or
third time the object
disappears. I think there?s a problem with the thml updater.
Are there some more examples about drag&drop or does some documentation
about it exists?
renderPlaceholdersOn: html
1 to: self numberOfPlaceholders do: [: index|
html unorderedList
with: [html listItem
class: 'placeholder';
with: [self
renderPlaceholder: ('ph' , index printString) asSymbol
on: html]]]
renderPlaceholder: aSelector on: html
html div
id: 'placeholder' , aSelector asString last asString;
class: 'placeholder';
style: 'width: ' , (self getPlaceholderWidth: aSelector) printString
, 'px';
script: (html droppable
accept: #('visual');
hoverclass: 'hover';
onDrop: (html updater
id: (self getPlaceholderId: aSelector);
triggerPassenger: [:value | (self perform: aSelector) add:
value.];
callback: [ :renderer | self renderPlaceholder: aSelector
on: renderer]));
with: [self renderPlaceholderItemsFrom: aSelector on: html]
renderPlaceholderItemsFrom: aSelector on: html
(self getPlaceholder: aSelector) do: [ :each |
html div
class: 'visual';
passenger: each;
script: (html draggable
revert: true;
onDropped: (html updater
id: (self getPlaceholderId: aSelector);
triggerPassenger: [:value | self onDropped: aSelector]));
with: [each asVisualObjectOn: html in: self]]
any ideas what I?m doing wrong?
Marco
