行背景颜色 GtkTreeView 小部件
我正在尝试将 gtk 树视图小部件中禁用的行着色为浅灰色。根据我所读到的内容，我应该设置相应 cellrenderer 的 background-gdk 属性并将其绑定到模型列。这种作品。
Gtk::CellRendererText* textRenderer = manage(new Gtk::CellRendererText());
textRenderer->property_editable() = false;
Gtk::TreeViewColumn *col = manage(new Gtk::TreeViewColumn("Column1", *textRenderer));
col->add_attribute(*textRenderer, "background-gdk", m_treeview_columns.m_back_color);
my_treeview.append_column(*col);
Gtk::TreeModel::Row row;
for (int i = 0; i < NUMBER_OF_ROWS; iLane++){
row = *(treeview_liststore->append());
row[m_workListColumns.m_back_color] = Gdk::Color("#CCCCCC");
}
但最终，我只得到正确着色的单元格。但我在单元格之间也发现了一个丑陋的空白。有谁知道解决这个问题的方法或者更好的方法来达到我想要的效果？
I'm attempting to color disabled rows in a gtk tree view widget a light gray color. From what I've read, I'm supposed to set the background-gdk property of the corresponding cellrenderer and bind it to a model column. This sort of works.
Gtk::CellRendererText* textRenderer = manage(new Gtk::CellRendererText());
textRenderer->property_editable() = false;
Gtk::TreeViewColumn *col = manage(new Gtk::TreeViewColumn("Column1", *textRenderer));
col->add_attribute(*textRenderer, "background-gdk", m_treeview_columns.m_back_color);
my_treeview.append_column(*col);
Gtk::TreeModel::Row row;
for (int i = 0; i < NUMBER_OF_ROWS; iLane++){
row = *(treeview_liststore->append());
row[m_workListColumns.m_back_color] = Gdk::Color("#CCCCCC");
}
In the end though, I get only the cells colored properly. BUT I also get an ugly white-space in between the cells. Does anyone know of a way to fix this or a better way to achieve the effect I'm after?

您能否将行的背景设置为与单元格背景相匹配或将树视图的背景设置在一起？或者也许是带有 cell-background-gdk 的单元格？
Could you set the background of the row to match the cell background or set the bakground of the tree view all together ? Or maybe the cell with cell-background-gdk ?
