I have a screen where some textfields I want to show a 'fake' keyboard. The keyboard should be able have as many buttons as I like and be displayed however I want. Just as shown below.
My question then is how do you accomplish something like this?
Is it possible to somehow override the interface to the keyboard so you consume the input and can display a 'fake' keyboard. And then remove the 'fake' keyboard when clicking on the back button on any other textfield which uses the normal keyboard.
Or do I have to create a custom #Composable or TextView with custom callbacks, and also render the text cursor manually?
You can implement your own TextInputService or provide null to completely disable the default input service:
CompositionLocalProvider(
LocalTextInputService provides null // or myTextInputService
) {
TextField(
value = text,
onValueChange = { text = it },
)
}
where myTextInputService is something like:
TextInputService(object : PlatformTextInputService {
//TODO implement methods
}

PROBLEM :::
I want to change the layout, more specifically hide or show the components in the layout based on the user click events.
I have attached a screen recording of the final result.
PLEASE VISIT THIS LINK FOR FINAL RESULT
THINGS WHICH I CAN TRY :::
Create same layout with components and load that layout when user clicks on button. But I know it's the very inefficient way.
you can create a isVisible value and add the layout between an if braces.
val isVisible = remember { mutableState(false) }
if (isVisible) {
content()
}
Button(onClick = { isVisible.value = true })
Ive got a working grid, using in-line editing thanks to this example
https://www.telerik.com/kendo-angular-ui/components/grid/editing/editing-row-click/
What I need to do now, is force the saving upon a user hitting the enter key, instead of clicking away onto another row or away from the current row. I suppose I could add a "save" button in the header?
You could probably use cellClose event in your html (cellClose)="cellCloseHandler($event)" - API Documentation
You could then write your own code (in typescript) in cellCloseHandler() to modify and save the updated items accordingly.
From Kendo UI for Angular Documentation:
In-Cell Editing
You could capture the Enter key hits and force executing cellCloseHandler() like that:
#HostListener('keydown', ['$event'])
public keydown(event: any): void {
console.log("keydown event", event);
if (event.keyCode === 13) {
this.cellCloseHandler();
}
}
Similar to Giannis answer but with small modifications:
Add keydown event to kendo-grid tag.
Call grid.closeCell() instead of calling the closeHander directly.
Template
<kendo-grid #grid
[data]="data$ | async"
(cellClose)="cellCloseHandler($event)"
(keydown)="onKeydown(grid, $event)"
>
Class
onKeydown(grid: GridComponent, e: KeyboardEvent) {
if (e.key === 'Enter') {
grid.closeCell();
}
}
cellCloseHandler(args: CellCloseEvent) {
const { formGroup, dataItem } = args;
// save to backend etc
}
Calling grid.closeCell(); will make the grid to call cellCloseHandler
You dont have to implement a HostListener for Keydown by yourself. If you set the input navigable to true, the cellClose event will get triggered when pressing Enter while editing a cell or row. This way you get the data of the row in your cellCloseHandler aswell for saving it.
<kendo-grid [navigable]="true" (cellClose)="cellCloseHandler($event)"></kendo-grid>
I want to be able to go to options menu in the game I am developing and set up my controls.
It is a simple game of pong (for now) and the controls for each player are just up and down.
This is how I want the process to look like: I click SETUP CONTROLS, game displays the name of the control I am supposed to change and it waits, I click the button on keyboard that i want it to be changed to, game reads it and displays the next control I am supposed to change and so on until i change all controls.
I have found a way how to do that here and my code now looks basicly like this:
if (optionsBList.IsButtonClicked("SETUP CONTROLS")) //when i click the
//SETUP CONTROLS button
//in the options menu
{
KeyboardState currentKeyboardState = new KeyboardState();
waitingForKey = true;
while (waitingForKey)
{
if(currentKeyboardState.GetPressedKeys().Count() > 0)
{
player1.upkey = currentKeyboardState.GetPressedKeys()[0];
//the path for the key isn't player1.upkey, but lets say it is.
waitingForKey = false;
}
}
}
In this short code my goal is to change just one key. If I can make it change 1 key, changing more wont be a problem.
The problem is, I don't see why does my game stop responding when i click the SETUP CONTROLS button. I don't see an infinite loop here nor a memory leak.
Why is my game crashing and is there a better way to load controls in options menu?
If you saw the answer from the link you placed in your question, you would have noticed that he actually deleted the while loop and he made it an if statement.
Like Nico Schertler said : "while(waitingForKey) is your infinite loop. That loop blocks the game thread, so no further input is recognized."
Link to the answer from your link: https://stackoverflow.com/a/15935732/3239917
if (optionsBList.IsButtonClicked("SETUP CONTROLS")) //when i click the
//SETUP CONTROLS button
//in the options menu
{
KeyboardState currentKeyboardState = new KeyboardState();
waitingForKey = true;
if (waitingForKey )
{
if(currentKeyboardState.GetPressedKeys().Count() > 0)
{
player1.upkey = currentKeyboardState.GetPressedKeys()[0];
//the path for the key isn't player1.upkey, but lets say it is.
waitingForKey = false;
}
}
}
I have a flash movie I am making that has a search box and a search button. The button has this code:
on (release, keyPress "<Enter>") {
searchbox.execute();
/*the function above processes searches*/
}
Clicking on the button works just fine. Pressing Enter doesn't do a bean! Does anyone know why this is, and any ways I can work around it? I'd prefer not to use listeners if I can possibly avoid it at all.
Using on() is a deprecated AS1 practice, so maybe you should just stop using it. Thanks to the onKeyDown event handler of the MovieClip class, it is possible to use proper code to do it without listeners, so you don't have to worry about them. ;)
Anyway, on with the code. Type this into the timeline which contains the button:
//Enable focus for and set focus to your button
searchButton.focusEnabled = true;
Selection.setFocus(searchButton);
//The onRelease handler for the button
searchButton.onRelease = function(){
//You need this._parent this code belongs to the button
this._parent.searchbox.execute();
}
//The onKeyDown handler for the button
searchButton.onKeyDown = function(){
//Key.getCode() returns the key code of the last key press
//Key.ENTER is a constant equal to the key code of the enter key
if(Key.getCode() == Key.ENTER){
this._parent.searchbox.execute();
}
}
I am trying to build a custom button in newest BlackBerry 10 platform.
The button should change background image when it is clicked and then change it back when it is clicked the second time.
The button logic is fairly simple: once clicked, I check for the type of image currently in the button and change the image source.
I started with a basic QML custom control which looks like this (stripped of labels and other unimportant things):
import bb.cascades 1.0
Container
{
id: root
layout: DockLayout
{
}
function clickMe()
{
var source = myImage.defaultImageSource.toString();
console.log(source);
if (source.endsWith("image.png"))
{
myImage.defaultImageSource = "asset:///images/image_pushed.png";
}
else
{
myImage.defaultImageSource = "asset:///images/image.png";
}
}
ImageButton
{
id: myImage
defaultImageSource: "asset:///images/image.png"
}
onCreationCompleted:
{
myImage.clicked.connect(root.clickMe);
}
}
ImageButton click event is connected to JavaScript function clickMe. The function fires and the URL is logged to console correctly.
The problem is the IF clause, because the image_pushed.png is never set. Why is this the problem and how can I implement this button?
I am looking around for a only QML solution for this problem and I found this information:
the defaultImageSource property is of type QUrl, which does contain
toString() method.
toString() method returns QString, which indeed has function endsWith.
my QML reference: http://qt-project.org/doc/qt-4.8/qstring.html#endsWith
Thanks.
Within QML QString instances appear to be a normal JavaScript strings. This mapping is done automatically. And Javascript strings don't have a endsWith method. You can use the search method with an regular expression to achieve the same.
if (source.search(/image\.png$/ !== -1) { /* ... */ }
I think you can create more simple way by using property
for example:
Control{
id : myControl
property bool state
ImageButton{
defaultImageSource : state ? "firstImageAsset.png" : "secondImageAsset.png"
onClick :{
myControl.state = !myControl.state
}
}
}
