MLenable/disable a WTreeTable and all of its subnodes

Added by Michael Leitman over 14 years ago

Hello out there :)

Due to user-right handling in my application,
it starts with a "not clickable" WTreeTable (per setting this->m_treeTable->disable();)

At first i create a TreeTable, then adding it as a Widget to a Layout
and at last calling disable().

For testing, on reaction to a Button Click, i enable the treeTable, calling this->m_treeTable->enable();

But then, only the "first level nodes" are clickable,
if i expand a Node, which contains subnodes, these are not available.

Is that supposed to be?
If yes, how can i en/disable all nodes and subnodes of a treetable?

I attached code, which represents my test case.
As seen in my code, the same process works for a WTreeView!

PS: oh, and i have another question, regarding WTreeView:
Using a WTreeTable, i can simply delete the current selection with
WTreeTable->tree()->clearSelection()

How would this look alike using a WTreeView?
I tried WTreeView->selectionModel()->selectedIndexes().clear(); but this did not work :(

thank you for every help

EDIT:
I just discovered another strange (in my eyes) behavior:

If i set a TristateCheckbox in the WTreeView header like
mode->setHeaderFlags(0, Horizontal, HeaderIsTristate | HeaderIsUserCheckable);
and set Sorting Enabled: treeView->setSortingEnabled(col, false);

and then set the whole WTreeView to disabled,
it's still available and the user can sort columns and select the tristate checkbox in the header?

Hey,

1) Indeed, WTreeTable::disable()/enable() and WTreeView::disable()/enable() require some extra work.

Could you file this as a bug ?

2) WTreeView::setSelectedIndexes(WModelIndexSet()) will clear the selection.
