近期库房想在出库存放区划分货位存放不同客户拣货后的商品数据。
同时需要在货位摆放屏幕以便显示当前货位被那个客户拣货占用,及商品信息、拣货状态等
由于独立项目,数据来源于api接口,所以只是一个客户端轮播即可。故拿wpf来试试demo
设计为:
1、一个主界面为控制台控制第2,3,....屏显示不同客户(货位)的信息去请求不同的数据
2、第2、3...屏的轮播数据展示
实现:
1、创建项目net下都一致,略过
2、控制不同屏幕轮播不同信息,只需要相关配置即可,这里略过
3、显示轮播信息这里使用一个按钮跳转来完成
<Button Grid.Column="2" Content="滚动" Name="btn_scroll" Width="100" Click="btn_Scroll_Click"/>
跳转到次屏
private void btn_Scroll_Click(object sender, RoutedEventArgs e) { ScrollWindow w = new ScrollWindow(); MultipScreenManager.ShowInScreen(w); }
这里使用到一个主次屏管理,引用了某一位博主(当前忘记了是哪一位,有知道的通知我补登)的MultipScreenManager
public static class MultipScreenManager { #region Property internal static Screen[] AllScreens { get { return Screen.AllScreens; } } internal static Screen PrimaryScreen { get { return Screen.PrimaryScreen; } } internal static IEnumerable<Screen> MinorScreens { get { return Screen.AllScreens.Where(o => o.Primary == false); } } internal static Screen FirstMinorScreen { get { return MinorScreens.FirstOrDefault(); } } #endregion Property #region Method public static void ShowInScreen(this System.Windows.Window win) { SetScreen(win); win.Show(); } public static void ShowDialogInScreen(this System.Windows.Window win) { SetScreen(win); win.ShowDialog(); } private static void SetScreen(System.Windows.Window win) { var attr = win.GetType().GetCustomAttributes(typeof(MultipScreenAttribute), false).FirstOrDefault(o => o is MultipScreenAttribute); int index = 0; bool ingoreOperation = false; WindowStartupLocationInScreen inScreen = WindowStartupLocationInScreen.CenterScreen; if (attr != null) { var temp = (attr as MultipScreenAttribute); index = temp.Index; inScreen = temp.InScreen; ingoreOperation = temp.IngoreMinorScreenError; } Screen screen = PrimaryScreen; if (index == 1 && FirstMinorScreen != null) { screen = FirstMinorScreen; } else if (index > 1 && index < MinorScreens.Count()) { screen = MinorScreens.ElementAt(index); } else if (index > 0 && index >= MinorScreens.Count() && ingoreOperation) { return; } switch (inScreen) { case WindowStartupLocationInScreen.CenterScreen: SetWindowInScreenCenter(win, screen); break; case WindowStartupLocationInScreen.Manual: SetWindowInScreenManual(win, screen); break; } } private static void SetWindowInScreenCenter(System.Windows.Window win, Screen screen) { win.Top = screen.WorkingArea.Y + (screen.WorkingArea.Height - win.Height) / 2; win.Left = screen.WorkingArea.X + (screen.WorkingArea.Width - win.Width) / 2; } private static void SetWindowInScreenManual(System.Windows.Window win, Screen screen) { win.Top = screen.WorkingArea.Y; win.Left = screen.WorkingArea.X; } #endregion Method } [AttributeUsage(AttributeTargets.Class)] public class MultipScreenAttribute:Attribute { public MultipScreenAttribute(ScreenType type = ScreenType.Primary, WindowStartupLocationInScreen inScreen = WindowStartupLocationInScreen.CenterScreen) : this((int)type, inScreen) { } public MultipScreenAttribute(int index = 0, WindowStartupLocationInScreen inScreen = WindowStartupLocationInScreen.CenterScreen) { Index = index; InScreen = inScreen; } /// <summary> /// 在窗体初始化显示的位置 /// </summary> public WindowStartupLocationInScreen InScreen { get; private set; } /// <summary> /// 屏幕索引, 0为主屏,1+为次屏 /// </summary> public int Index { get; private set; } /// <summary> /// 当任何指定次屏没有找到时,如果该值为TRUE,则忽略这个页面的显示,否则将显示在主屏 /// </summary> public bool IngoreMinorScreenError { get; private set; } } public enum ScreenType { /// <summary> /// 主屏 /// </summary> Primary = 0, /// <summary> /// 次屏 /// </summary> Minor = 1, } public enum WindowStartupLocationInScreen { Manual = 0, CenterScreen = 1, }

注意点:
让次屏全屏显示时让width、height=获取到的屏幕大小
开启timer设置间隔时间轮播,默认从第一页开始,设定每屏幕可轮播的行数,到最后一页后重新从第一页轮播
也可以开启鼠标经过轮播体时暂停,离开时继续:MouseEnter="ScrollWindow_MouseEnter" MouseLeave="ScrollWindow_MouseLeave"
Storyboard的DoubleAnimation设置属性控制进入轮播的进入效果及位置等
需要ui好看点,可以引入皮肤库,这这里使用了:MaterialDesign
只需要在app.xaml中增加配置:
<Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml"></ResourceDictionary> <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" ></ResourceDictionary> <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.DeepPurple.xaml"></ResourceDictionary> <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Lime.xaml"></ResourceDictionary> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources>
然后在使用页面引入:xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
