Drag and Drop in ListView



I am trying to drag and drop a ListView row and I am having trouble at the drag stage. Below code doesn't drag anything and name column is not aligned properly. I don't want to specify a size for ListView and I want it to get its size from its content Row with id row. It should be able to because text has size coming from its font size and Rectangle has set width. ListView can get wider as needed to show the name part.


Row


import QtQuick 2.11
import QtQuick.Layouts 1.11

ListView
id: root
height: scrollview.viewport.height

model: listModel
delegate: dragDelegate

Component
id: dragDelegate

MouseArea
id: dragArea

anchors left: parent.left; right: parent.right
height: content.height

drag.target: pressed ? content : undefined
drag.axis: Drag.XAndYAxis

Rectangle
id: content
anchors
horizontalCenter: parent.horizontalCenter
verticalCenter: parent.verticalCenter

height: row.implicitHeight

border.width: 1
border.color: "lightsteelblue"
color: "green"
radius: 2
states: State
when: dragArea.pressed

ParentChange target: content; parent: root
AnchorChanges
target: content
anchors horizontalCenter: undefined; verticalCenter: undefined


Row
id: row

Text
text: name
font.pointSize: 15

Rectangle
height: parent.height
width: 40
color: hexColor






ListModel
id: listModel
ListElement
name: "first-name"
hexColor: "red"

ListElement
name: "second-name"
hexColor: "green"

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
