Using jsTree with checkbox and state plugin, each time I check some checkboxes and reload page they are still checked. How is possible to use state plugin with checkboxes, but "forget" checkbox state (leaving opened and selected node state as is).
plugins : ["grid", "state", "dnd", "types", "checkbox"],
I created some example jsFiddle.
Thanks!
Use the state.filter option:
filter : function (state) {
delete state.checkbox;
return state;
}
Here is the updated fiddle:

I've been searching non-stop for this on the documentation but haven't been able to find any sort of information. I would like to know how to add checkboxes in my custom view container, similar to the breakpoints' checkboxes.
You can simulate the checkbox by playing with the icon, create a new TreeItem with a different icon when clicked.
Somehow they have knowledge on where on the TreeItem you click.
Looking with the dev tools, it is an <input type="checkbox"/>.
This means that you can do more with TreeItems than the docs explain.
Looking at the source code the BreakpointView is not implemented with a TreeItemProvider, it extends the ViewPane class and uses some kind of templates to render an item. Beside a checkbox it is also possible to have a combobox (SelectBox class).
I have added a feature request (101175) to extend the vscode API so extension developers can write Views with ViewItems that have additional UI-Elements like the Breakpoint view.
You can do this in the proposed api: treeItemCheckbox in Insiders v1.72 now and since it is a fairly simple new api I suspect it will be released with Stable 1.72.
You can play with this now, see using the proposed apis.
Instead of extending TreeItem you will extend TreeItem2 (which extends TreeItem) if you want to use checkboxes. Here is some sample code I put together:
export class TreeTab extends vscode.TreeItem2 {
...
if (tab.isActive) {
this.iconPath = new vscode.ThemeIcon("arrow-small-right", new vscode.ThemeColor("tab.unfocusedActiveBackground"));
this.checkboxState = vscode.TreeItemCheckboxState.Checked;
// this.checkboxState = {state: vscode.TreeItemCheckboxState.Checked, tooltip: "my nifty checkbox tooltip"};
}
...
and elsewhere in your code if you want to detect when that checkbox is clicked/unclicked:
// use your TreeView variable instead of 'tabView'
// from this.tabView = vscode.window.createTreeView(...);
const checkBoxListener = this.tabView.onDidChangeCheckboxState(async event => {
// event = {item: Array(n)}, which TreeItem's checkbox was clicked and its state after clicking:0/1 = on/off
console.log(event);
});
I have a dropdown list with few rows in a table. All the dropdown are required fields. if none of the dropdown list has been selected and a user select only one dropdown and tries to save. A validation error is thrown which is correct, the problem is the value for the selected dropdown choice gets reset to "Choose one". how can i correct that?
Wicket uses the IChoiceRenderer#getIdValue() to find the selected option. If you do not provide custom IChoiceRenderer then Wicket will use ChoiceRenderer and as an id it will use the index of the item in the List of options.
See the usages of #equals() at https://github.com/apache/wicket/blob/7bef3d67c8ccc269f02e8943bf9a22c3cd5438e9/wicket-core/src/main/java/org/apache/wicket/markup/html/form/AbstractSingleSelectChoice.java. Even better fire the debugger and see what happens!
I am experimenting cobrowsing with Angular 6 Forms.In co-browsing an opensource library togetherJS updates the DOM value of corresponding element for remote party.I have updated togetherJS related code in index.html(two line one in head and another in body) I have observed using ControlValueAccessor Form type DOM value of corresponding element is getting updated but FormControl value is not getting updated in view.
My question is how changes done by an external library on DOM elements can be reflected into angular 6 form control's element value in view.
One can get the code from below link:
https://github.com/srigaurav1986/Angular-Forms.git
How to reproduce:
1.Download code from above link.
2.Install dependencies using "npm install"
3.Run "ng serve -o"
4.open in browser "http://localhost:4200/controlvalueaccessor"
5.Click on "Start TogetherJs"
6.Copy the popped link in another browser window.
7.Update the "Name" field
We can see DOM field value is also getting updated on remote side but after pressing "Submit" button we can see FormControl value remains unaltered on remote side but changed on other side.
I tried using manually detecting changes using application.tick,markforcheck() and detectchanges() apis but no luck.Is there a way, where we can listen to some event on DOM element change and subscribe to it and also update the Formcontrol parameter values in such case.
The answer to this question lies in angular(6) property that it works on shadow DOM and only listen to the changes happening within angular zone , when the third party library like TogetherJS updates DOM corresponding changes doesn't effect angular components as they are not subscribe to actual DOM native element.
In order to resolve this issue we did following :
Register one call back in Form class constructer to capture DOM “change” events triggered from Co-Browsing library i.e. happening outside angular zone as mentioned below:
Code Snippet
constructor(private formBuilder: FormBuilder,private elementRef: ElementRef,private _renderer: Renderer,private cdr:ChangeDetectorRef,private app:ApplicationRef,private zone:NgZone) {
zone.runOutsideAngular(() =>{
window.document.addEventListener('change', this.change.bind(this));
})
}
Define the eventHandler to perform below actions :
Run in Angular context using this.zone.run()
Use ElementRef to get the component’s template selector.
Run queryselector on input elements and compare with event’s outerHTML to check which element has changed in component.
Set the Formcontrol’s value for matching element.
PS: Here customerForm is ControlValueAccesor FormGroup type of instance. In your case it can be your form. We can generalize form( In case reactive) key traversal as mentioned in another SO post
Angular 2: Iterate over reactive form controls
Code Snippet:
change(event){
event.preventDefault();
console.log("DOM value changed" ,event);
console.log("component value", this.elementRef.nativeElement);
this.zone.run(() => { console.log('Do change detection here');
//this.cdr.detectChanges();
if(this.elementRef.nativeElement.querySelectorAll('input')[0].outerHTML === event.target.outerHTML)
{
console.log('Inside value updation');
//this.customerForm.controls.name.value=event.target.value;
this.customerForm.controls['name'].setValue(event.target.value);
}
});
setTimeout(() =>{
this.cdr.markForCheck();
})
}
This will set the respective values of elements(obviously via traversing loop) changed in component and validation should not fail as it’s happening in current context.
The core idea of above details is how to capture change events happening outside angular zone and updating angular application accordingly.
PS : I shall update the full code in github for other's perusal.
I made a combobox using sap.m library:
var oSelection = new sap.m.ComboBox({
name: <name>,
id: <id>,
items: {
<items here>
})
},
});
Now, how do I make this field kind of read only, so when I tap it on mobile, it wouldn't bring up the mobile's keyboard, but it would bring up the selection options?
I've tried to use editable: false, but it disables the selection together with keyboard.
Thank you.
From what I could find out there's no method that allows such behaviour.
One option, that I personally would not advice, is to access the HTML DOM and disable the input field that composes the sap.m.Combobox component.
Keep in mind that if the development SAPUI5 changes the inner workings of the Combobox component your code could be broken if you update the SAPUI5 libraries.
This being said, to use this option you could do something like:
oSelection.onAfterRendering = function() {
if (sap.m.ComboBox.prototype.onAfterRendering) {
sap.m.ComboBox.prototype.onAfterRendering.apply(this);
}
document.getElementById("<id>-inner").disabled=true;
}
replace the < id>-inner by the correct id given to your component.
This was tested using version 1.22.8 of SAPUI5 development toolkit.
Use sap.m.Select instead of sap.m.ComboBox.
Select does not provide the ability to edit the field content.
In many instances the Select control can directly replace a ComboBox without any other changes to the properties or the items aggregation!
I'm using the Add Form to add records to my JQGrid. One of the fields is a checkbox. Does anyone know how to have the checkbox to be defaulted to checked when the form displays. I thought it would use the onInitializeForm event and the setCell method but I'm having no luck. Thanks.
Found it:
beforeShowForm: function(eparams) {
document.getElementById('calc_next_svc').checked = 'true';
}
}, // add options
