PyGTK TreeView 中的粗体/非粗体行
我想将 TreeView 中的一些行设为粗体，而有些行则不将它们附加到 TreeView，稍后，我想在单击时取消粗体行。
做到这一点最简单的方法是什么？
I want to make some rows in my TreeView bold, and some not as I append them to TreeView, later on, I want to unbold rows on click.
What is the easiest way to do this?

我假设您有一个模型，其中包含带有一些文本的列，并且
gtk.CellRendererText小部件的text属性设置为该模型中的列索引。如果向该模型添加新列，则可以使用它来设置每个单元格渲染器中使用的字体粗细。为此，只需将
gtk.CellRendererText小部件weight属性设置为模型中的新列索引，并将weight-set设置为True。之后，您只需使用任何
pango.WEIGHT常量（例如pango.WEIGHT_NORMAL和pango.WEIGHT_BOLD）在模型中设置字体粗细代码>.举个例子，假设这些是您的模型列（一列用于文本，一列用于字体粗细）：
这些是您添加用于测试的几行：
（请注意
pango.WEIGHT_NORMAL=400和pango.WEIGHT_BOLD=700）使用此模型，您可以创建一个带有列和文本渲染器的
gtk.TreeView：在渲染器中，将
text属性设置为模型中的text列：和
weight属性添加到模型中的weight列：使用以下命令获得的结果您添加到模型中的测试数据是：
您可以在其中看到文本以模型中设置的字体粗细显示。
I assume that you have a model that contains a column with some text and that a
gtk.CellRendererTextwidget has atextproperty set to the column index in that model.If you add a new column to that model you can use it to set the font weight used in every cell renderer. To do that just set the
gtk.CellRendererTextwidgetweightproperty to the new column index in the model andweight-settoTrue.After that, you just need to set the font weight in the model using any of the
pango.WEIGHTconstants such aspango.WEIGHT_NORMALandpango.WEIGHT_BOLD.As an example, let's say that these are your model columns (one for the text, one for the font weight):
and these are a couple of rows that you've added for testing:
(Note that
pango.WEIGHT_NORMAL=400andpango.WEIGHT_BOLD=700)With this model, you create a
gtk.TreeViewwith a column and a text renderer:In the renderer you set the
textproperty to thetextcolumn in the model:and the
weightproperty to theweightcolumn in the model:The result that you obtain with the test data that you added to your model is:
Where you can see that the text is displayed with the font weight that is set in the model.
