1) 確かに!これは多かれ少なかれ QML の目的です。
2)これは、あなたが望むことを行う方法の例です(それを行う唯一の方法ではありません):
Rectangle {
id: parentRect
width: 500; height: 500
// Every item in the grid should look like this
Rectangle {
id: singleItem
color: "red"
state: "closed"
// Hidden text input, shown when user clicks
TextInput {
id: textInput
anchors.fill: parent
text: "Input here"
cursorVisible: true
}
// MouseArea that will catch the user click
MouseArea {
anchors.fill: parent
onClicked: singleItem.state = "open"
}
// Item states
states: [
State {
name: "closed"
PropertyChanges {target: singleItem; width: 25; height: 25}
PropertyChanges {target: textInput; opacity: 0}
},
State {
name: "open"
PropertyChanges {target: singleItem; width: parentRect.width; height: parentRect.height}
PropertyChanges {target: textInput; opacity: 1; focus: true}
}
]
// Transitions between states
transitions: Transition {
ParallelAnimation {
NumberAnimation {
target: singleItem
properties: "width,height"
duration: 1000
}
NumberAnimation {
target: textInput
property: "opacity"
duration: 1000
}
}
}
}
}
