Actually, I'm trying to use a combo-box in Ext.Net to select a value from its selecting list. This combo-box is editable and user can type any value he want.
On selecting list, I want to prevent user from selecting the highlighted item by pressing Enter key and let him just select it by mouse click. for this, i tried to use an listener on bound list "ItemKeyDown" but it did nothing. Other events related to mouse par example, working fine but all events related to key are not working.
I don't know if i have missed something in configurations or what.
Anyone can give me any advise to make theses listeners work?
Thanks in advance,
var combo = Html.X().ComboBox().DisplayField(mark).ValueField(type).Editable(true)
.ID(combo_id).EnableKeyEvents(true).AutoSelect(false).SelectOnFocus(true)
.QueryMode(DataLoadMode.Local).ValidateOnBlur(false).ValidateOnChange(false)
.ListcConfig(Html.X().BoundList()
.Listeners(l => l.ItemKeyDown.Handler = "console.log('ItemKeyDown');")); /// ItemKeyDown not displayed in console.
I post the solution i got from Ext.Net support team so if someone need it in future:
#(Html.X().ComboBox()
.Listeners(events => {
events.Expand.Handler = #"this.listKeyNav.map.removeBinding({
key: Ext.EventObject.ENTER
});";
events.Expand.Delay = 1;
events.Expand.Single = true;
})
)

My extension have sidebar webview that can create additional webviews as panels in the active text editor. Each of these additional webviews is for an unique item and I want to revive/activate existing webview, for the specific item, if it exists.
My issues:
I can get a list of the existing tabs with window.tabGroups.all and loop through the result. But there is no way, as far as i can see, to reactivate the desired tab. I can get some properties from there but no methods. The question here is: is there a API to get a list of the tabs and be able to revive/activate it?
Because of the first point ive decided to keep list of the instances of the additional webviews and when new webview is about the be created im checking if its unique id (in the title) is in the list and if it is then just revive the tab instead of creating a new one. Dont like this approach much but its working. The problem here is when the additional webview is closed. When closed it has to be removed from the array. Ive implemented onDidDispose for the panel but somehow the filter function, inside it, is not called:
// panels: vscode.WebviewPanel[]
// create new panel
const panel = vscode.window.createWebviewPanel(...)
// add the webview instance to the panel
const newWebview = new AdditionalWebview(panel, this.context);
this.panels.push(panel);
panel.onDidDispose(() => {
console.log("Before remove the panel"); // can see this in the console
this.panels = this.panels.filter((p) => p.title != panel.title);
console.log("Before remove the panel"); // for some reason this never appears
});
Not sure why but the panel filter functionality is never triggered (and everything after it is also not ran).
extra question: at the moment the uniqueness of the additional panels is based on their label/title. In my case thats is ok but is there any other way to get unique identifier of each tab? id/guid somewhere?
On your first question about activating a given editor, you have a couple of options.
If you know the editor's index/position in its group. That can be obtained from its tabGroup.tabs position - it seems that the tab's index in that array is faithfully its index in the editor. So you could do a Array.findIndex to get the tab uri you want to set to active.
await vscode.commands.executeCommand('workbench.action.openEditorAtIndex', [indexToOpen]);
// note the [] around the index argument
The only problem with this approach is that it works within the active group only, so you may have to activate the correct group first via:
await vscode.commands.executeCommand('workbench.action.focusSecondEditorGroup');
// or whichever group the tab you want to open is in
Or second method:
// assumes you have the tab
const openOptions = { preserveFocus: true, preview: tab.isPreview, viewColumn: tab.group.viewColumn};
// check if a uri, might be viewtype, etc., instead
if (tab.input instanceof vscode.TabInputText) {
await vscode.commands.executeCommand('vscode.open', tab.input.uri, openOptions);
}
// are your editors regular text editors?
This looks like it is opening a new tab but it will focus an existing tab if one exists at that location with that same uri.
It is my first time asking here, sorry if i do something wrong (also not in my mother tongue).
Recently, i moved from Swing&AWT to JavaFX.
I am discovering the new Table which is quite different from the Swing version. Better i would say, it needs less operation and do more things, but ... lord, it's way more difficult to understand !
I am currently trying to modify the TableView dynamically. While the addColumn method is not a big challenge, i need help for my deleteColumn method :/
Let's talk about my problem :
I have a scene with many components on it (panes, buttons, menus, ...) and one pane (actually an anchorpane) hosts a TableView.
I would like to dynamically delete an entire column when this operation occurs :
The user right clicks on the TableView > a contextual menu shows up > he selects the item "delete"
So, basically a contextual menu that offers the option to delete the column where the user right-clicked.
I tried this :
-> When the user right-clicks on the TableView, this method is called :
public void setTargetForContext(ContextMenuEvent event){
if(event.getTarget() instanceof Label){
ObservableList list =(((Label)event.getTarget()).getChildrenUnmodifiable());
activeColumn = ((Text)((ObservableList)list)).getText();
}...
And the goal was to set the column name in "activeColumn".
Then, when the user will select the "delete" option from the contextual menu, another method would be called to compare the name of the columns and delete the right one.
But it seems that i can't call a getChildren() method on the label, only an unmodifiable one. And it does not allow a cast and throw the exception.
Do you have a solution to allow me to get the column name ?
Or maybe i am going the wrong way and i have to find another way to delete the right-clicked column, but in this case i will need your help too.
Thanks a lot for reading, and thanks in advance for your help.
First, let me point out that if you call
table.setTableMenuButtonVisible(true);
then the table will have a built-in menu button with radio buttons allowing the user to select which columns are displayed. Maybe this is all you need.
In Swing, the renderers for table cells are just "rubber stamps" that are painted onto the table. Thus you can't register listeners for UI events with them.
By contrast, in JavaFX, the cells in a table are real UI controls with full functionality. This means there's no real need for API that gets the cell coordinates from a table. You should not register your listener with the TableView, but with the actual cells on which you want to operate. You access the cells from the table column's cell factory.
// the table:
TableView<RowDataType> table = new TableView<>();
//...
// A table column:
TableColumn<RowDataType, CellDataType> column = new TableColum<>("Header text");
// A context menu for the table column cells:
ContextMenu contextMenu = new ContextMenu();
MenuItem deleteColumnItem = new MenuItem("Remove Column");
deleteColumnItem.setOnAction(e -> table.getColumns().remove(column));
contextMenu.getItems().add(deleteColumnItem);
// Cell factory for the column
column.setCellFactory(col -> {
// basically a cell with default behavior:
TableCell<RowDataType, CellDataType> cell = new TableCell<RowDataType, CellDataType>() {
#Override
public void updateItem(CellDataType item, boolean empty) {
super.updateItem(item, empty);
if (item == null) {
setText(null);
} else {
setText(item.toString());
}
}
});
// add the context menu to the cell:
cell.setContextMenu(contextMenu);
return cell ;
});
If you want the context menu to appear in the table column header as well, you just need to do
column.setContextMenu(contextMenu);
Please let me know the best xpath for the below HTML, the button id's are dynamically populated. Hence I tried using the starts-with function as below
driver.findElement(By.xpath("*//button[starts-with(#id, 'j_idt')]")).click();
but, how to achieve if we have two buttons in the same page as per the attached screenshot.
There are multiple ways to find the button. One of the options is to rely on the text inside, e.g. for Login:
//button[span = 'Login']
Then, you can add other checks, e.g. check if it is of type submit:
//button[#type = 'submit' and span = 'Login']
I am having a UltraListView and some items with checkbox in it. Now I have to disable the specified checkbox with help of index give.
For eg: If i provide '0' then i should get the first checkbox disabled and if I provide '1' the second checkbox should get disabled.
//Code
Me.lvUnlink.Items(O).Control.ViewSettingsList.CheckBoxStyle = UltraWinListView.CheckBoxStyle.CheckBox
I tried like the above code and it disables all the checkboxes. How can I achieve this?
There are different approaches to solve this task. Maybe one of the easiest solutions could be if you are using instance of UltraListViewItemCheckBoxUIElement. For example:
UltraListViewItemCheckBoxUIElement elem = e.Element.GetDescendant(typeof(UltraListViewItemCheckBoxUIElement),ultraListView1.Items[3]) as UltraListViewItemCheckBoxUIElement;
if (elem != null) elem.Enabled = false;
If you want to disable/enable specific item/items using an index, you should specify the context in your GetDescendant() method

I have two related ComboBoxes ( continents, and countries ). When the continents ComboBox changes I request a XML from a certain URL. When I receive that XML i change the DataProvider for the countries ComboBox, like this:
public function displayCountryArray( items:XMLList ):void
{
this.resellersCountryLoader.alpha = 0;
this.resellersCountry.dataProvider = items;
this.resellersCountry.dispatchEvent( new ListEvent( ListEvent.CHANGE ) );
}
I dispatch the ListEvent.CHANGE because I use it to change another ComboBox so please ignore that (and the 1st line ).
So, my problem is this: I select "ASIA" from the first continents, then the combobox DATA get's updated ( I can see that because the first ITEM is an item with the label '23 countries' ). I click the combo then I can see the countries.
NOW, I select "Africa", the first item is displayed, with the ComboBox being closed, then when I click it, the countries are still the ones from Asia. Anyway, if I click an Item in the list, then the list updates correctly, and also, it has the correct info ( as I said it affects other ComboBoxes ). SO the only problem is that the display list does not get updated.
In this function I tried these approaches
Converting XMLList to XMLCollection and even ArrayCollection
Adding this.resellersCountry.invalidateDisplayList();
Triggering events like DATA_CHANGE and UPDATE_COMPLETE
I know they don't make much sense, but I got a little desperate.
Please note that when I used 3.0.0 SDK this did not happen.
Sorry if I'm stupid, but the flex events are killing me.
Setting the dataprovider of the comboBox' dropdown seems to fix this problem.
this.resellersCountry.dataProvider = items;
this.resellersCountry.dropdown.dataProvider = items;
this.resellersCountry.dropdown.dataProvider = items;
works (Flex SDK 3.5)
Hope this bug fixed in 4.0
In addition to Christophe´s answer:
When you are using data binding in your ComboBox you need to use the BindingUtils to set the dropdown´s dataprovider:
MXML:
<mx:ComboBox id="cb_fontFamily"
width="100%"
dataProvider="{ model.fontFamilies }" />
Script:
private function init():void
{
BindingUtils.bindSetter(updateFontFamilies, model, "fontFamilies");
}
private function updateFontFamilies(fontFamilies:ArrayCollection):void
{
if (cb_fontFamily != null) cb_fontFamily.dropdown.dataProvider = fontFamilies;
}
Thanks to Christophe for pointing in the right direction.
Another workaround, outlined in an Adobe Community forum post, is to avoid re-assigning a different ArrayCollection object to the ComboBox, and instead re-using (and re-populating) the original one instead:
items.removeAll();
for each (var item:* in newItems)
{
items.addItem(item);
}
