如何将键盘焦点放到弹出的Gtk.Window上 [英] How to give keyboard focus to a pop-up Gtk.Window

问题描述

我有一个弹出式窗口（使用WINDOW_POPUP类型创建），其中包含一些小部件，包括文本条目。问题是，当我点击它时，条目没有得到重点，所以我不能输入任何内容。是否有任何标志我必须设置，以允许窗口获得键盘焦点？

解决方案

您不能使用WINDOW_POPUP for gtk - 需要重点的窗口。相反，您应该使用类型为GTK_WINDOW_TOPLEVEL的GtkWindow并调用下一个函数（或方法）。
$ b $ pre $ GtkWindow * result = g_object_new（GTK_TYPE_WINDOW， type，GTK_WINDOW_TOPLEVEL，NULL）;
gtk_widget_set_can_focus（result，TRUE）;
gtk_window_set_decorated（GTK_WINDOW（result），FALSE）;
gtk_window_set_type_hint（GTK_WINDOW（result），GDK_WINDOW_TYPE_HINT_POPUP_MENU）;
gtk_window_set_transient_for（GTK_WINDOW（result），main_top_level_window）;


这对我有用......不幸的是，当这个弹出窗口时，窗口列表中的图标闪烁'被销毁

I have a pop-up window (created using the WINDOW_POPUP type) which contains some widgets on it, including a text entry. The problem is that the entry doesn't get the focus when I click on it, so I can't type anything. Is there any flag I have to set to allow the window to get the keyboard focus?

解决方案

You can not use WINDOW_POPUP for gtk-windows that require the focus. Instead you should use a GtkWindow with type GTK_WINDOW_TOPLEVEL and call the next functions (or methods)

GtkWindow *result = g_object_new(GTK_TYPE_WINDOW, "type", GTK_WINDOW_TOPLEVEL, NULL);
gtk_widget_set_can_focus(result, TRUE);
gtk_window_set_decorated(GTK_WINDOW(result), FALSE);
gtk_window_set_type_hint(GTK_WINDOW(result), GDK_WINDOW_TYPE_HINT_POPUP_MENU);
gtk_window_set_transient_for(GTK_WINDOW(result), main_top_level_window);

This worked for me ... unfortunately the icon in the window-list blinks short when this 'popup' is destroyed
