A little tricky, but I found a way to get it working. I don't think it has a scroll bar, which makes it kind of useless for long lists. Maybe an idea for our own gtkdialog development, though, since I'm sure it would get used a lot.

I just thought of a way to do long lists. Here is the basic idea:

Place a button above and below the space where a subset of the full list is shown.

When someone clicks on the up button, the dialog closes, and a new one opens with the list scrolled down by 1/2 the length of the sub-list you are showing. Te script needs to keep track of the state ON/OFF of the items in the full list and give the subset back with the right combination of check marks.

I have made a thing that works like a combo-box but allows the user entry to be filtered on a keystroke basis. This used the fact that there is an event for the loss of focus. If the scrolled list is done in its own box, this trick could be used to make the list a stand alone thing.

Could this be used-

Code:
<tree selection-mode="3"


It gives you multiple selection capability with a scroll bar.

Cheers,

This works fine. It ( selection-mode="3") gives you the possibility to select several files.

But how to distinguish (sort out) the selected and unselected items?

All the selected items are returned separated in this variable-
Code:
<variable>TREECHOICES</variable>

Not as pretty as checklists, but works nicely. <ctrl> clicking returns multiple items.

Yes, checklists would be my favorite as well, but "tree" is also usable. I'd just never heard about the attribute "selection-mode". Everything i'd tried gives me only single-file-selection. But this one works and i can use it for my work.

To put the whole selection into a text file use
Code:
echo $TREE1 > /tmp/list


To write the whole selection as single lines into a text file use
Code:
for i in $TREE1;
   do
      echo $i >> /tmp/list
   done

Here's a version using tree. In batch mode, the "batch copy" button opens the tree list. Select with <ctrl> click, and then push the "select pets" button.
This opens an editable box for final selection. Push the "Make Pets" button for creation in /tmp

edit: added a "select all" button in tree list

jpeps,

Nicely done.

I've found it easier to build gtkdialog menu items this way-
Code:

for i in *.files;do
i=${i//.files/}
LIST="$LIST<item>"$i"</item>"
done
echo $LIST # becomes input variable item list for combobox


It grabs only the ".files", cuts off the ".files" extension, and makes up the list variable all in one shot.

Regards,
s

I do use this one, which works also fine. It uses original funcItemCreate.

Code:
  <tree selection-mode="3" stock="gtk-file">
    <label>"'$WFNALST'"</label>
    <height>200</height><width>300</width>
   '"$(funcItemCreate)"'
    <variable>TREEOUTPUT</variable>
  </tree>


To write complete selection as single lines into a text file use
Code:

for i in $TREEOUTPUT;
   do
      echo $i >> /tmp/list
   done

I select "Batch Mode" then clicking on "Batch Copy" - nothing happens.

Output after running gnewpet:
Code:
** (gtkdialog:31852): WARNING **: create_tree(): A TreeView with no label.
**
ERROR:automaton.c:1833:connect_tree_signals: assertion failed: (tree_view != NULL && Attr != NULL)
Aborted

Yes, this is exactly, what i'd meant and it looks good. Does it work or is it just step 1?

Inserting "<label>Batch Pets</label>" after <tree selection-mode="3"> inside your gnewpet script executes the batch window - but it is empty. Confused

Clicking on "Select Pets" opens another empty window. Shocked

Clicking on "Select All" opens a window with all files listed. Smile

Clicking OK inside full list window executes nothing. Shocked Confused

Batch list in /tmp/batch is existing Exclamation
