好吧,我正在开发简单的应用程序,用于启动/停止和重新启动单声道的LAMP(只是为了了解更多单声道的GUI开发),所以为了减少按钮,我决定使用一个按钮来启动和停止服务器。在GUI设计器中,我添加了带图标的开始按钮,问题是更新按钮标签很容易,但将图像更改为Stock.MediaStop有点问题。那么如何在点击事件中更改按钮中的股票图像(它不会计算它实际上是什么类型的事件)。这里有一些代码: 按钮的GUI XML:
<widget class="Gtk.Button" id="button1">
<property name="MemberName" />
<property name="CanFocus">True</property>
<property name="Type">TextAndIcon</property>
<property name="Icon">stock:gtk-media-play Menu</property>
<property name="Label" translatable="yes">Start</property>
<property name="UseUnderline">True</property>
<signal name="Clicked" handler="OnMysqlServerStartStop" />
</widget>
这里MediaDevelop如何使用自定义文本创建Stock按钮:
// Container child hbox1.Gtk.Box+BoxChild
this.hbuttonbox1 = new Gtk.HButtonBox();
this.hbuttonbox1.Name = "hbuttonbox1";
// Container child hbuttonbox1.Gtk.ButtonBox+ButtonBoxChild
this.button1 = new Gtk.Button();
this.button1.CanFocus = true;
this.button1.Name = "button1";
this.button1.UseUnderline = true;
// Container child button1.Gtk.Container+ContainerChild
Gtk.Alignment w2 = new Gtk.Alignment(0.5F, 0.5F, 0F, 0F);
// Container child GtkAlignment.Gtk.Container+ContainerChild
Gtk.HBox w3 = new Gtk.HBox();
w3.Spacing = 2;
// Container child GtkHBox.Gtk.Container+ContainerChild
Gtk.Image w4 = new Gtk.Image();
w4.Pixbuf = Stetic.IconLoader.LoadIcon(this, "gtk-media-play", Gtk.IconSize.Menu, 16);
w3.Add(w4);
// Container child GtkHBox.Gtk.Container+ContainerChild
Gtk.Label w6 = new Gtk.Label();
w6.LabelProp = Mono.Unix.Catalog.GetString("Start");
w6.UseUnderline = true;
w3.Add(w6);
w2.Add(w3);
this.button1.Add(w2);
this.hbuttonbox1.Add(this.button1);
答案 0 :(得分:2)
我明白为什么你在这里遇到这么多麻烦。我认为您可以设置按钮的图像和文本属性,但似乎您可以显示标签或显示图像,但不能同时显示两者。标签会覆盖图像。我认为图像只会在主题设置要求时显示。这同样适用于标签。您可以将两者结合使用,仅标签或仅图像。全部由您使用的主题设置。
您在这里的正确轨道上,此示例代码应该回答您的问题。
using System;
using Gtk;
namespace TogglePlay
{
public class MainClass
{
private bool stop = false;
private Image image;
private Label label;
public MainClass ()
{
Button button = new Button();
VBox box = new VBox();
image = new Image(Stock.MediaPlay, IconSize.Button);
box.PackStart(image, true, true, 0);
label = new Label("Start");
box.PackStart(label, true, true, 0);
button.Add(box);
button.Clicked += OnButtonClicked;
Window window = new Window("LAMP light");
window.Add(button);
window.DeleteEvent += DeleteWindow;
window.ShowAll();
}
private void DeleteWindow(object obj, DeleteEventArgs args)
{
Gtk.Application.Quit();
}
public void OnButtonClicked(object widget, EventArgs args)
{
if (!stop) {
stop = true;
image.Stock = Stock.MediaStop;
label.Text = "Stop";
} else {
stop = false;
image.Stock = Stock.MediaPlay;
label.Text = "Start";
}
}
public static void Main(String[] args)
{
Gtk.Application.Init ();
MainClass mainClass = new MainClass();
Gtk.Application.Run ();
}
}
}
