Have a main 'checkbox' that controls the behavior of child checkboxes and then change its state based on user actions - Hope this helps!

to combo1 put currentIndexChanged, which will change combo2.setCurrentIndexdef set_combo2(): text = self.combo1.currentText() index = date_list.index(text) self.combo2.setCurrentIndex(index) self.combo1.currentIndexChanged.connect(set_combo2)

No, you're doing something wrong.Separate your logic on VM and View.First VM. I don't know what type of line you're gonna have, we're gonna name it as a frame. S♪You need the following:static public class Styles { public static ReadOnlyList<S> All { get; } = ...; // тут все стили } Next, the current style should be available as a characteristic of your VM, if the relevant characteristic is called CurrentStyle♪Okay, next XAML. You do something like that: The list of all styles is tied through ItemsSourcecurrent selected style through SelectedItem♪ You need more. ItemTemplatewhich will describe what the line of this style looks like.<ComboBox ItemsSource="{x:Static vm:Styles.All}" SelectedItem="{Binding CurrentStyle}" HorizontalContentAlignment="Stretch"> <ComboBox.ItemTemplate> <DataTemplate> <Border Height="15" Name="Outer"> <Line X1="0" X2="{Binding ActualWidth, ElementName=Outer}" Y1="8" Y2="8" Stroke="Black"/> </Border> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> ♪ DataTemplate'Cause you need to describe what this style line looks like. The necessary properties will be available through Binding♪ Like, if it's easy. StrokeDashArrayYours. CurrentStyle Must be like DashArray or class containing a type DashArray♪ By contacting him: <Line X1="0" X2="{Binding ActualWidth, ElementName=Outer}" Y1="8" Y2="8" Stroke="Black" StrokeDashArray="{Binding}"/> Here's the picture:

Join the slot button. Inside the elephant, place the data from the view to the variables and cause the function:void onPushPressed() { auto dateTime1 = mDateTimeWidget1.dateTime(); auto dateTime2 = mDateTimeWidget2.dateTime(); auto comboValue = mComboBox.currentText(); foo(dateTime1, dateTime2, comboValue); }

As you've noticed, you need to. Cosmeticsas in Excel There are no built-in instruments that can help to realize the idea.Macrose. But until they picked the list, there's no event that we can solve the code.It seems that there are no restrictions that the author has indicated.

There is a component of ImageList for such purposes.

I' questions later.We need to remove the street list by taking names from the variable name with the help method getNamestreetList.setCellFactory(p -> new ListCell <Street> () { @Override protected void updateItem(Street item, boolean empty) { super.updateItem(item, empty); if (item != null &amp;&amp; !empty) { setText(item.getName()); } else { setText(null); } } }); a When selecting a certain street, start processing events through new ones. ChangeListener(s) {...}.streetList.getSelectionModel().selectedItemProperty().addListener((observable, oldValue, newValue) - > { //тут описываешь логику лисенера }); I used the lambdu here, not new ChangeListener()...But that's what happens if Lenin's on the list for example, Lenina? And the first option is a prospect, the second one is the street, but in the first place. This should not be marked.You'll have a street spectacle if you have objects. Street different methods (to be redesigned) hashCode() and equals())UPDATEAbout the picture in the commentary, there are two ways.Redesign the method toString() in class StreetReclassify buttonCell as follows:streetList.setButtonCell(new ListCell < Street > () { @Override protected void updateItem(Street item, boolean empty) { super.updateItem(item, empty); if (item != null && !empty) { setText(item.getName()); // или любую другую логику тут можно написать } else { setText(null); } }

The problem is that the chosen web is not displayed in the combobox until you find the mouse. That's why the combobox spits and the window spits behind it. If you take it away. SizeToContent="WidthAndHeight", you can see a window of normal size and a combobox without the chosen web.The chosen Web is displayed only if SelectedIndex placed outside the event Loaded (e.g., in the design of the windows or in the button compression process) or if in the event Loaded Lines are added as web sites, not control elements. To be honest, it looks like the WPF's bug and can only be shown on certain versions of the framing/OS.

I'm working like this:XAML:<ComboBox ItemsSource="{Binding}" x:Name="CB" TextBoxBase.TextChanged="OnComboboxTextChanged" IsTextSearchEnabled="False" IsEditable="True" VerticalAlignment="Top"/> Code-behind:void OnComboboxTextChanged(object sender, RoutedEventArgs e) { CB.IsDropDownOpen = true; // убрать selection, если dropdown только открылся var tb = (TextBox)e.OriginalSource; tb.Select(tb.SelectionStart + tb.SelectionLength, 0); CollectionView cv = (CollectionView)CollectionViewSource.GetDefaultView(CB.ItemsSource); cv.Filter = s => ((string)s).IndexOf(CB.Text, StringComparison.CurrentCultureIgnoreCase) >= 0; } Result:

Without the wisdom of the torch, you can accommodate Label by standard ComboBox and write what you need.But if you want, you can turn yourself in. We need to send a message. https://msdn.microsoft.com/ru-ru/library/windows/desktop/bb775897(v=vs.85).aspx by function https://msdn.microsoft.com/en-us/library/windows/desktop/ms644950(v=vs.85).aspx ♪using System.Runtime.InteropServices; class WatermarkedComboBox : ComboBox { protected override void OnHandleCreated(EventArgs e) { const uint CB_SETCUEBANNER = 0x1703; base.OnHandleCreated(e); if (IsHandleCreated) { SendMessage(Handle, CB_SETCUEBANNER, IntPtr.Zero, "Watermark"); } } [DllImport("user32.dll", CharSet = CharSet.Unicode)] private static extern IntPtr SendMessage(IntPtr hWnd, uint msg, IntPtr wp, string lp); } The fountain inscription (watermark) will be visible in the combox when it's not in focus and when no meaning is chosen in it.

You have a mistake in this place:if (cb.getSelectedItem().equals("horse") && s.equals("сено") || s.equals("трава")) { lblImage.setIcon(horse); l.setText(hfood); } You say if you're chosen. and "Seno" or It's "trave," it's a horse's icon. I mean, by throwing the grass, you'll have a horse's icon in any animal.Whatever it is, you just need to put the brackets in, that is, if the horse is chosen. and (Seno) or "tra."if (cb.getSelectedItem().equals("horse") && (s.equals("сено") || s.equals("трава"))) { lblImage.setIcon(horse); l.setText(hfood); }

Just give appropriate weight to the character of your combobox. B value shall be the value specified in value Field, as suchvar states = Ext.create('Ext.data.Store', { fields: ['abbr', 'name'], data : [ {"abbr":"AL", "name":"Alabama"}, {"abbr":"AK", "name":"Alaska"}, {"abbr":"AZ", "name":"Arizona"}, //... //... //... //... //... //... {"abbr":"testValue", "name":"it's work!"} ] }); Ext.create('Ext.form.ComboBox', { fieldLabel: 'Choose State', store: states, queryMode: 'local', displayField: 'name', valueField: 'abbr', value: 'testValue', renderTo: Ext.getBody() });

Prompt like this:for i := 0 to ComboBox1.Items.Count -1 do begin ComboBox1.ItemIndex := i; ComboBox1Select(nil); Application.ProcessMessages; end; But it's a bad decision. Better avoid the challenge. Application.ProcessMessagesas this slows the work of the annex and can lead to unpredictable consequences.

You've transferred the mass to the combo box. Lines:String[] idNumbers; ... combo.setModel(new DefaultComboBoxModel(idNumbers)); Method getSelectedItem() returns the element chosen, which is a line (some line from the transferred area). How do you want a number? If you need the number of the element chosen, use it. combo.getSelectedIndex();If you've got strings of chisel in the strings, use it. Integer.parseInt(combo.getSelectedItem())

The question is no longer relevant.If anyone's interested, the size of the print changes in the parameter. fieldStyle:fieldStyle: { 'font-size': "25px" },

сombobox1.Items and contains a set of values. Why take him somewhere. Or you can use lambda expression if you need to typify it from ObjectCollection♪

It's probably gonna be enough to come into character. ComboBox and write to him DisplayMember the name of the column, which should be displayed as a text.You've got nothing in there right now, and you're looking at everything. DataRowView♪ More specifically, his string performance is displayed. DataRowView.ToString()- type name.

The implementation list is a full upper-level window. It's not a daughter's window, and the size of the original counter is not changing.To solve the problem of losing focus, use it. Form.ShowWithoutActivation:protected override bool ShowWithoutActivation { get { return true; } } P. S. You're ineffective. If you need a complex stewardship and not killed in the zero of usability and accessibility (standard logic is more than you think), then look towards WPF. It's where it's maintained from a box and doesn't require cycling from scratch.

Except for the selection of the elements on the list, combobox also allows for the introduction/relevance (method) set()) When you change. current()at the same time, value changes (may see by method) get()) That's because you don't give a meaning, it's an empty line. So just put it back in the empty room and get it. -1♪combo.current(0) print(combo.current(), combo.get()) combo.set("") print(combo.current(), combo.get()) combo.set("Not in the list") print(combo.current(), combo.get()) 0 1 -1 -1 Not in the list
