How does Babylon recognizing text selection in any software? I have to implement this.
Thanks.
Provided your just using Babylon just for your 3D content and html for your UI, try window.getSelection(). You could call this on a mouseup event, as you'd expect this to occur at the end of the highlight process.
Something like...
const elem = document.getElementById('yourDiv);
let textSelection;
elem.addEventListener('mouseup', ()=> { textSelection = window.getSelection() })

I have a map in my angular application OpenLayers map.
During the test using testcafe, I have to zoom out, but I have no way how to do that.
I only have to put my mouse at the center of the screen, and then scroll down to zoom out.
Already tried using ClientFunction with scrollBy and etc but nothing happens in map.
Thank you
Find out on which element the handler you need hangs and what event it listens to. This is most likely a 'mousewheel' event. This should help you:
const zoom = ClientFunction(zoomSize => {
const event = new WheelEvent('wheel', { deltaY: zoomSize });
document.querySelector('#zommed-element').dispatchEvent(event);
});
I have three columns, two with divs and the central one with an svg. I made a method that calculate the top() of each paragraph inside the divs to get the position and then draw an arrow in the svg. The problem is that when I use that method the first time I open my component, I get all zeroes, probably because the paragraph aren't really drawn (they have no coordinates) yet. I tried in mounted(), which should be the right place to do that. I use it also in updated() in case I reload my json with new data.
Am I missing something trivial?
The code I use to get the coordinates is like this:
drawLine(index1, index2) {
//var plist1 = this.$refs['p_list1'];
//var plist2 = this.$refs['p_list2'];
var plist1 = document.getElementsByClassName('p_list1');
var plist2 = document.getElementsByClassName('p_list2');
if (plist1.length == 0 && plist2.length == 0) return;
var svg = document.createElementNS('http://www.w3.org/2000/svg', 'line');
//...
//const start = this.$refs['startpos'].getBoundingClientRect().top;
const start = document.getElementById('startpos').getBoundingClientRect().top;
const r1 = plist1[index1].getBoundingClientRect();
const r2 = plist2[index2].getBoundingClientRect();
index1 and index2 comes from a loop where I get which paragraph I have to connect with an arrow (also where the nextThick is)
Here is a simple example of the issue:
https://codesandbox.io/s/bootstrap-vue-test-bcozc
Note: it's badly shown, but if you press "DO" and then switch tab, you'll see that the arrow aren't correct. If you switch tab and then press DO, it will work.
Put your calculation methods in a $nextTick function to allow parents and children to fully render.
If that does not work, as a debug step, try using a setTimeout method to delay the calculation.
After understanding that the problem was linked to how tabs are built, I tried making that specific tab lazy and it worked.
<b-tab lazy ...
I don't know how tabs are normally built, but I suppose the dom is put together without having a real coordinate system and when it's made visible, I don't have any event to read to update the svg.
I have two editors on the screen, one read-only. What I want to do is allow the user to select content from the read-only editor and paste it into the current position of the other by clicking a button. (the logic may manipulate the text which is one reason I don't want to use the system's clipboard.)
So far I have the function that is able to paste the text like as follows. (I am using the Angular wrapper which explains the presence of the CKEditorComponent reference.
doPaste(pasteEvent: PasteEvent, editorComponent: CKEditorComponent) {
const editor = editorComponent.editorInstance;
editor.model.change(writer => {
writer.insertText(pasteEvent.text, editor.model.document.selection.getFirstPosition() );
});
}
What I can't find from the documentation is how to extract the selected text. What I have so far is:
clickPasteSelectedPlain(editorComponent: CKEditorComponent) {
const editor = editorComponent.editorInstance;
const selection = editor.model.document.selection;
console.log('clickPasteAll selection', selection);
console.log('clickPasteAll selectedcontent', editor.model.document.getSelectedContent);
}
The selection appears to change depending on what is selected in the editor's view. The getSelectedContent function is undefined. How do I get the content?
With a bit of poking around I figured out how to do this. I'll document it here on the chance that it will help someone down the road avoid the process of discovery that I went through.
On the source document I have a ckeditor element like this:
<div *ngIf="document">
<ckeditor #ckEditor
[editor]="Editor" [config]="ckconfig" [disabled]="true"
[(ngModel)]="document.text"></ckeditor>
<button mat-flat-button (click)="clickPasteSelectedPlain(ckEditor)">Paste Selected Text Plain</button>
</div>
In the component the function called on the click event is like this:
#Output() paste = new EventEmitter<PasteEvent>();
...
clickPasteSelectedPlain(editorComponent: CKEditorComponent) {
const editor = editorComponent.editorInstance;
this.paste.emit({
content: editor.model.getSelectedContent(editor.model.document.selection),
obj: this.document,
quote: false
});
}
The PasteEvent is defined as an exported interface which I will omit here to save space. The content key will refer to a DocumentFragment.
Note that I am passing the CKEditorComponent as a parameter. You could also access it via an Angular #ViewChild declaration but note that my ckeditor is inside an *ngIf structure. I think that works well in Angular 6 but in the past I have had difficulty with #ViewChild references when the target was conditionally in the DOM. This method always works but use whatever method you want.
The event fired by the emit is processed with a method that looks like this:
doPaste(pasteEvent: PasteEvent, editorComponent: CKEditorComponent) {
const editor = editorComponent.editorInstance;
editor.model.insertContent(pasteEvent.content);
}
Because the content is a DocumentFragment the paste operation will include all formatting and text attributes contained in the selected source. But that's all there is to it.
I have a TextArea in a modal Window. When the modal window is displayed, I want the focus to be set to this TextArea. I also want the TextArea to have default text when it is displayed & the cursor to be at the beginning of this text.
I call focus() on TextArea when modal window is displayed & in the focus() handler, I set the text that I want & call setSelection(0, 0) to move the cursor to position 0.
This doesn't seem to be working as the cursor remains at the end of the set text.
I am using the latest version of the SDK.
It would be great if someone could help me fix this issue. Thanks!
Titanium SDK: 3.0.2 Target platform: IOS only
Here's the code:
// 'statusUpdateArea' is my TextArea
$.tabbedBarNav.addEventListener('click',function(e)
{
statusUpdateArea.focus();
}
statusUpdateArea.addEventListener('focus',function()
{
statusUpdateArea.setValue(" - I am here'");
//API to set cursor at beginning doesn't work!!!!!! [or I don'tknow how to use it :( ]
statusUpdateArea.setSelection(0, 0);
});
Don't focus. setSelection will focus the text area for you. Focusing is preventing the selection from being properly set. Uncomment the .focus call to see it not work.
Try the following. It works for me on iOS with Titanium SDK 3.x.
var win = Ti.UI.createWindow({
backgroundColor: '#fff'
});
var textArea = Ti.UI.createTextArea({
value: 'Some text.'
});
win.add(textArea);
win.addEventListener('open', function(evt) {
// textArea.focus();
textArea.setSelection(0, 0);
});
win.open();
Use hintText for default..You cant set the text like that.. actual setSelection is not for cusor movement . it is used to select a part of value in text field...so u cant use that method...use hint text and let the user to type ..later on u can add the default text to value of text feild it might be useful..
I got the answer to this on the Appcelerator dev forum. There seems to be a bug with the implementation on IOS:

can anyone please explain, with an example if possible, how to load dynamic content inside an iscroll div and assign a new height to it?
I can get it to work but I can't control the height of the scroll for the new content.
I'm new to all this and have no clue were to start.
here's what I'm working on:
http://homepage.mac.com/jjco/test/index7.html
when the page is loaded you see the scroll bar where there's no content...
clicking on print/damm (shows the height I originally set for this content)
clicking on print/fcbarcelona (maintains the same height and position of the scroll you used before) as you see it's not working as it should.
obviously, I don't want the scroll to be there when it's not necessary.
any help would be greatly appreciated.
It's better to use the refresh() method in iScroll, which will recalculate the height.
myScroll.refresh();
I had a similar problem, and just refresh() didn't help, so didn't help destroying and recreating iScroll. In my case I was loading a lot of elements into iScroll div. What did solve the problem is setTimeout(). As MASTERING THE REFRESH() METHOD said adding even 0ms to a setTimeout() would solve a lot of problems. In my case it was 500ms. =
here is code sample:
var myScroll;
function createIScroll(){
myScroll = new iScroll('wrapper');
}
function iScrollRefresh(){
setTimeout(function(){
myScroll.refresh();
}, 500);
}
$ajax(){
//receiving data
}
function someFunction(){
//dynamic content is created
iScrollRefresh();
}
My problem was that refresh() function was executed before content was inserted into DOM, so increasing timeout helped. I hope it helps to beginners like me.
try this, when you insert your new data into iScroll do these steps
//myScroll is a global variable you initialize iScroll on
myScroll.destroy();
myScroll = null;
loaded();//this is a functions where you have have your iScroll initializer
To watch height changes:
setInterval(function () {
var newScrollerHeight = $scroller.innerHeight();
if (newScrollerHeight !== prevScrollerHeight) {
prevScrollerHeight = newScrollerHeight;
myScroll.refresh();
}
}, 500);
Take a look at iScroll4
In iscroll.js, I see experimental option: checkDOMChanges: false,// Experimental You can enable and use it.
