Fixed QueryTextbox Binding event

[Sparrkle]

Fixed an error when typing QueryTextBox in specific language.
For example, if the user enters "안녕하세요" and presses the Enter key immediately, it will be searched as "안녕하세".

korean works well. I think there would have been similar problems with Chinese or Japanese.
(I've been through this problem for a long time, but I couldn't find a solution. In the end, I was mainly used in English.)
If there is no problem in other languages, it is better to apply it.

Thanks for the fix! Could you explains a bit why PropertyChange is not enough for triggering change to source for other language (is it because of ime)?

[Sparrkle]

In the case of Hangul, initial, neutral, and final letters are combined to form one letter.
However, it is assumed PropertyChanged event will be triggered when the next initial is passed because only the initial and neutral can be entered.

I am worried by whether this may trigger too much unnecessary result when user use input method like for Chinese. Before the text is typed in, the query is triggered and the querytext will not change.

Flow.Launcher/Flow.Launcher/ViewModel/MainViewModel.cs

Lines 329 to 336 in c81dd32

	public string QueryText
	{
	get => _queryText;
	set
	{
	_queryText = value;
	Query();
	}

Please also add a equality check here (note for requery, which is handled in a different way

Flow.Launcher/Flow.Launcher/ViewModel/MainViewModel.cs

Lines 344 to 359 in c81dd32

	public void ChangeQueryText(string queryText, bool reQuery = false)
	{
	if (QueryText != queryText)
	{
	// re-query is done in QueryText's setter method
	QueryText = queryText;
	// set to false so the subsequent set true triggers
	// PropertyChanged and MoveQueryTextToEnd is called
	QueryTextCursorMovedToEnd = false;
	}
	else if (reQuery)
	{
	Query();
	}
	QueryTextCursorMovedToEnd = true;
	}

).

fixed a bug not triggered while the backspace was pressed.

lol do you want to change the binding mode to oneway?

[Sparrkle]

It looks like a oneway but it works twoway.

[taooceros]

Sorry I mean these two (Any difference between them)

[Sparrkle]

I just tested it and it works the same :'( There is no difference.
