Python PyGOobject树视图:使用Tab键在单元格之间移动后确认编辑 [英] Python PyGOobject treeview: confirm edit after move between cells with Tab key

问题描述

搜索了很长时间之后，我发现了一个解决方案(非常简单)，可以使用Tab键在维护的单元格之间移动，并在编辑模式下维护单元格.

After searching for a long time I found a solution (pretty simple) to move between cells of a treeview grid using Tab key and mantaining cells in edit mode.

现在我遇到了一个问题:仅在按Enter键之后才进行单元格编辑确认. 如果按Tab键，似乎会触发edit_cananceled事件.

Now I've got a problem: cell edit confirmation happens only after pressing Enter key. If I press Tab key a editing_canceled event appears to be triggered.

如何解决?如何在按Tab键时也允许数据确认?

How to solve it? How to permit the data confirmation also on tab key press?

这是我的Treeview按键事件的事件处理程序:

This is my event handler for treeview key-press-event:

def key_tree_Tab(self, treeview, event,namewidget):
    path, col = treeview.get_cursor() 
    ## only visible columns!! 
    columns = [c for c in treeview.get_columns() if c.get_visible()] 
    colnum = columns.index(col)     

    if event.keyval==65289:

        if colnum + 1 < len(columns): 
            next_column = columns[colnum + 1]               
            treeview.set_cursor(path,next_column,start_editing=True)                                    


        else: 
            tmodel = treeview.get_model() 
            titer = tmodel.iter_next(tmodel.get_iter(path)) 
            if titer is None: 
                titer = tmodel.get_iter_first() 
            path = tmodel.get_path(titer) 
            next_column = columns[0] 
            treeview.set_cursor(path,next_column,start_editing=True)

    return True

谢谢大家！!!!

推荐答案

我知道这个线程很久以前了.我使用当前版本的Python3和Gtk3尝试了您的代码，但无法正常工作.它仅适用于新行.现有行不会跳至下一个单元格.如果我添加"return True"，那么即使有现有单元格，每个单元格都可以按Tab键显示，但是没有一个单元格会更新.

I know this thread is long ago. I tried your code with current version of Python3 and Gtk3 and does not work. It works only with new rows. The existing rows do not tab to next cell. If I add "return True" then every cell can Tab even with existing cells, but none gets updated.
