在 PyGtk 中设置 GtkTreeViews 时遇到问题
我在一个扩展gtk.TreeView的类中得到了一些代码，这就是init方法。我想创建一个包含 3 列的树视图。一个切换按钮、一个标签和一个用户可以在其中输入内容的下拉框。下面的代码可以工作，只是切换按钮不会对鼠标单击做出反应，并且不会绘制标签和 ComboEntry。 （所以我想你可以说它不起作用）。不过，我可以很好地添加行。
#make storage enable/disable label user entry
self.tv_store = gtk.TreeStore(gtk.ToggleButton, str, gtk.ComboBoxEntry)
#make widget
gtk.TreeView.__init__(self, self.tv_store)
#make renderers
self.buttonRenderer = gtk.CellRendererToggle()
self.labelRenderer = gtk.CellRendererText()
self.entryRenderer = gtk.CellRendererCombo()
#make columns
self.columnButton = gtk.TreeViewColumn('Enabled')
self.columnButton.pack_start(self.buttonRenderer, False)
self.columnLabel = gtk.TreeViewColumn('Label')
self.columnLabel.pack_start(self.labelRenderer, False)
self.columnEntry = gtk.TreeViewColumn('Data')
self.columnEntry.pack_start(self.entryRenderer, True)
self.append_column(self.columnButton)
self.append_column(self.columnLabel)
self.append_column(self.columnEntry)
self.tmpButton = gtk.ToggleButton('example')
self.tmpCombo = gtk.ComboBoxEntry(None)
self.tv_store.insert(None, 0, [self.tmpButton, 'example label', self.tmpCombo])
I've got some code in a class that extends gtk.TreeView, and this is the init method. I want to create a tree view that has 3 columns. A toggle button, a label, and a drop down box that the user can type stuff into. The code below works, except that the toggle button doesn't react to mouse clicks and the label and the ComboEntry aren't drawn. (So I guess you can say it doesn't work). I can add rows just fine however.
#make storage enable/disable label user entry
self.tv_store = gtk.TreeStore(gtk.ToggleButton, str, gtk.ComboBoxEntry)
#make widget
gtk.TreeView.__init__(self, self.tv_store)
#make renderers
self.buttonRenderer = gtk.CellRendererToggle()
self.labelRenderer = gtk.CellRendererText()
self.entryRenderer = gtk.CellRendererCombo()
#make columns
self.columnButton = gtk.TreeViewColumn('Enabled')
self.columnButton.pack_start(self.buttonRenderer, False)
self.columnLabel = gtk.TreeViewColumn('Label')
self.columnLabel.pack_start(self.labelRenderer, False)
self.columnEntry = gtk.TreeViewColumn('Data')
self.columnEntry.pack_start(self.entryRenderer, True)
self.append_column(self.columnButton)
self.append_column(self.columnLabel)
self.append_column(self.columnEntry)
self.tmpButton = gtk.ToggleButton('example')
self.tmpCombo = gtk.ComboBoxEntry(None)
self.tv_store.insert(None, 0, [self.tmpButton, 'example label', self.tmpCombo])

首先，您需要创建一个包含
bool、str和str列的模型，而不是您现在所做的方式。其次，您需要从适当的模型列绑定渲染器的属性，例如，如然后您需要将渲染器上的
editable属性设置为True。最后，您需要自己处理信号（changed或editing-done，具体取决于渲染器类型）并相应地更新存储。使用一些助手可能会更容易，例如
Py-gtktree — 甚至还有一个编辑树的示例。
First of all, you need to create a model with
bool,strandstrcolumns, not the way you are doing now. Second, you need to bind properties of renderers from appropriate model columns, e.g. as inThen you need to set
editableproperty on the renderer toTrue. And finally, you need to handle signals (changedorediting-done, depending on renderer type) yourself and update the store accordingly.It may be easier to use some helpers, e.g.
Py-gtktree — there's even an example for editing a tree there.
只需连接 gtk.CellRendererToggle 中的
toggled信号，当您单击它时，它将发出该信号，然后在回调中更改模型中的值。ej。
self.model是与树视图关联的模型，Just connnect the
toggledsignal in the gtk.CellRendererToggle, when you click on it, it will emit that signal, then in your callback change the value in the model.ej.
self.modelis the model asociated to the treeview,
