I am using Vaadin 7.6.4 for my UI work. This has the following:-
I have a window which contains a grid with data in it. This window is actually a kind of a pop up[ which shows up when my main screen gets a click on the settings icon( not shown here). This is working fine( getting the UI screen to open the Vaadin window when the settings icon the main screen is clicked).
The problem is in showing the data as mentioned below.
This grid will have 4 columns for which the data comes from a bean container.
The first column is a boolean field with true/false getting displayed based on the data from the bean container.
I need to convert this boolean field column into a checkbox with true showing the field as a checkbox with a value selected. If the value is false, then show a checkbox which is not selected.
I am trying to do that as shown in the code below but I keep getting this checkbox name printed. I dont see the checkbox but the word "checkbox" printed in there?
This checkbox should be editable. The idea is that the user should be able to select some checkboxes and the ones selected should be shown in a panel ( not shown here). Thus, the checkbox has to be editable.
How do I fix this? The code for the window is shown below

}
Ok, we used the SelectionMode.MULTI to show the selection of rows in there.
https://cdn.vaadin.com/vaadin-core-elements/latest/vaadin-grid/demo/selection.html
Still, I would love to learn more as to how we get the change done as shown in the question above.
Still looking for an answer to that.
Use a Renderer and a Converter, you don't need to use SelectionMode.MULTI.
An example of this is posted here.

I have a couple of places in my UI where the user clicks an action and then I'd like to show a pop-up with (something like) a Dialog to invite him/her to add optional information, e.g. use a Picker to enter a date.
The idea is that this popup should be as little intrusive as possible and require as few clicks as possible, so I was thinking something like a Dialog with an explanation text and a Picker already activated so the user can directly swipe to the right date and push Done, and also a [Skip] button to directly close the Dialog without entering anything.
However, I've tried many different solutions and the picker (even in Light mode) appears outside the Dialog and I can't get the Dialog to close when clicking Done in the Picker.
Does anyone have a suggestion on how this could be achieved?
Here's how I finally implemented it, using the non-public components used by the Spinners (so the class must be placed in com.codename1.ui.spinner). I also noticed an issue in DateSpinner3D which sets the time of day randomly (to the time of activation), which means it may alter a Date even if not edited, but I'll do a PR for that.
I've only implemented support for the Picker elements I currently use.
So not fully reusable/generic solution, but hopefully it can help show how it can be done if anyone runs into the same need.
I've added a screenshot (only test colors): [![enter image description here][1]][1]

I have simple code:
ComboBox<String> combo=new ComboBox<>("Combo");
Button button = new Button("Button");
button.addClickListener(new ComponentEventListener<ClickEvent<Button>>() {
#Override
public void onComponentEvent(ClickEvent<Button> event) {
combo.setItems("11","22");
combo.setValue("22");
}
});
When I first time click button i have items "11" and "22" present in combobox and value "22" is selected.
Second click makes value cleared but items "11" and "22" are still present.
In case I select "11" or leave "22" selected in combobox and click button - value clears.
It seems that setValue() only works when combobox is empty but following code do not helps as well:
combo.setValue(null);
combo.clear();
combo.setItems("11","22");
combo.setValue(null);
combo.clear();
combo.setValue("22");
Following code sets value of ComboBox correctly, no matter if I select some value or clear it before click:
ComboBox<String> combo=new ComboBox<>("Combo");
combo.setItems("11","22");
Button button = new Button("Button");
button.addClickListener(new ComponentEventListener<ClickEvent<Button>>() {
#Override
public void onComponentEvent(ClickEvent<Button> event) {
combo.setValue("22");
}
});
But I have to set items of Combobox dynamically and the last solution do not suitable for me.
Vaadin version is 10.0.9.
Has anyone some suggestions or advices ?
PS.
Thanks !
I've tried following code:
combo.setItems(Collections.emptyList());
combo.setItems("11","22");
combo.setValue("22");
But it do not work as well.
This code works only if value in combo is empty, but if I input something in combo the code just clears value by .setItems() and further .setValue() do not work.
If value of combo is empty the code works well.
Your code works perfectly fine in a minimum project based on https://vaadin.com/start/latest/project-base (which uses Vaadin 12.0.7)
#Route("")
#PWA(name = "Project Base for Vaadin Flow", shortName = "Project Base")
public class MainView extends VerticalLayout {
public MainView() {
ComboBox<String> combo=new ComboBox<>("Combo");
Button button = new Button("Button");
button.addClickListener(new ComponentEventListener<ClickEvent<Button>>() {
#Override
public void onComponentEvent(ClickEvent<Button> event) {
combo.setItems("11","22");
combo.setValue("22");
}
});
add(combo,button);
}
}
Whatever value you set in the ComboBox via UI .. when the button is clicked, the selected value will switch to 22.
If that's an option for you, you could update to a newer Vaadin version and try it with that.
To better show what I meant in my comment, I'm writing it as an answer.
What I meant was to set an empty collection not in the clickListener but directly after initializing the ComboBox:
ComboBox<String> combo=new ComboBox<>("Combo");
combo.setItems(Collections.emptyList());
Button button = new Button("Button");
button.addClickListener(new ComponentEventListener<ClickEvent<Button>>() {
#Override
public void onComponentEvent(ClickEvent<Button> event) {
combo.setItems("11","22");
combo.setValue("22");
}
});
please try it out and let me know if that works
I am using codename one swipe tabs dynamically to prepare some radio button but on swiping of tabs getSelectedIndex () method is giving the previous tabs value(previous in the sense suppose I move my tabs from 0 to 1 so it's giving me 0) so how to get the current tab value at which my tab is because on basis of this selectedIndexTab value I want my radio button to get selected.
Here is my code
TableLayout t1=new TableLayout(1, 5);
radioTypeContainer=new Container(t1);
for(i=0;i<5;i++){
t.addTab("Tab2"+i, new SpanLabel("Some text directly in the tab"));
firstTab = new RadioButton[i];
plain = new RadioButton("");
plain.setName("rdb"+i);
rbt =new RadioButton();
rbt.setName("rbt"+i);
radioTypeContainer.add(rbt);
finalRadioList.add(rbt.getName());
finalRadioList.add(t.getTabUIID());
}
borderLayoutContainer.add(BorderLayout.SOUTH,radioTypeContainer);
t.addSelectionListener((i1, i) -> {
Log.p("====***======="+t.getSelectedIndex());
});
Thanks in Advance
newSelected in selectionchanged method gives the current position of tab as shown in below code.
t.addSelectionListener(new SelectionListener() {
#Override
public void selectionChanged(int oldSelected, int newSelected) {
Log.p("====***======="+newSelected);
}
});
my problem is:
i made a combobox and i want to use context menu on it's elements, so when i'm setting the cellfactory as shown below, i can't see the items in any more and the context menu does not show.
CBXGroups.setCellFactory(new Callback<ListView<String>, ListCell<String>>() {
public ListCell<String> call(ListView<String> param) {
final ListCell<String> cell = new ListCell<String>();
final ContextMenu cellMenu = new ContextMenu();
MenuItem rimuoviDalControllo = new MenuItem("RIMUOVI DAL CONTROLLO");
MenuItem rimuoviDefinitivamente = new MenuItem("RIMUOVI DEFINITIVAMENTE");
rimuoviDalControllo.setOnAction(new EventHandler<ActionEvent>() {
public void handle(ActionEvent event) {
Service.deleteGroupFromControl(cell.getText(),CBXControllo.getSelectionModel().getSelectedItem());
populateLists();
}
});
rimuoviDefinitivamente.setOnAction(new EventHandler<ActionEvent>() {
public void handle(ActionEvent event) {
Service.deleteGroup(cell.getText());
populateLists();
}
});
cellMenu.setOnShowing(new EventHandler<WindowEvent>() {
public void handle(WindowEvent event) {
cell.requestFocus();
}
});
cellMenu.getItems().addAll(rimuoviDalControllo,rimuoviDefinitivamente);
cell.contextMenuProperty().bind(Bindings.when(Bindings.isNotNull(cell.itemProperty())).then(cellMenu).otherwise((ContextMenu) null));
return cell;
}
});
You can't see the items because you haven't set the text in your ListCell. You can do this with a one-liner:
cell.textProperty().bind(cell.itemProperty());
The context menu is trickier, and I don't really have a solution for it. The issue is that the ComboBox uses a PopupControl to display the list view, and the popup control has autoHide set to true. So when you click on the list view, the popup closes (preventing you seeing the context menu). There's no way to access the popup control, so I don't think there's going to be any way to do this.
Registering a context menu with items in a combo box seems like an unusual thing to do; I wonder if there is a better approach for what you want to do. A MenuButton is similar to a ComboBox in some ways (control that displays a popup with options), but it has a menu hierarchy so you can include cascading menus. This might provide the kind of functionality you want.
I'm working on a desktop application. It has a dropdown menu. When a menu item is clicked on the dropdown a new tab is opened if it's not opened before. There is a single tab for a single dropdown menu item. What i want to do is to open a window, page or user control(i'm not sure which i should use) in seperate tabs considering the work they will do.
My partial XAML:
<dxd:DockLayoutManager DockItemClosing="DockLayoutManager_DockItemClosing_1">
<dxd:LayoutGroup>
<dxd:TabbedGroup Name="tabbedGroup">
</dxd:TabbedGroup>
</dxd:LayoutGroup>
</dxd:DockLayoutManager>
and partial CS:
private void addPanel(string caption)
{
var contains = false;
var layoutPanel = new LayoutPanel() { Caption = caption };
BaseLayoutItem[] baseLayoutItem = tabbedGroup.GetItems();
foreach (var layoutItem in baseLayoutItem)
{
if (layoutItem.Caption.Equals(layoutPanel.Caption))
{
contains = true;
}
}
if (!contains)
{
tabbedGroup.Add(layoutPanel);
}
}
As i mentioned i want to append a window, page or user control(i'm not sure which i should use) into every LayouPanel opened seperately.
Ok it's as easy as:
layoutPanel.Content = new UserControl1();
And i got one more trick for dynamically creating the desired tab:
layoutPanel.Content = Activator.CreateInstance(Type.GetType(Constants.s_tabs[caption]));
I hope it won't cause any performance problems.
