如何使用键盘快捷键切换搜索栏的可见性?
默认情况下,我想隐藏搜索栏。但是,然后用户按Ctrl + F我希望它可见。然后,当他们单击“ X”按钮时,它将再次隐藏。
MyContent.qml
if(led.endsWith("1"))
...
else if(led.endsWith("0"))
main.qml
import QtQuick 2.7
import QtQuick.Controls 2.0
import QtQuick.Layouts 1.3
ColumnLayout {
anchors.fill: parent
RowLayout {
width: parent.width
visible: true
TextField {
text: ""
placeholderText: qsTr("Search...")
selectByMouse: true
Layout.fillWidth: true
}
Button {
text: "x"
}
}
Label {
wrapMode: Text.Wrap
font.pixelSize: Qt.application.font.pixelSize * 1.1
Layout.fillWidth: true
Layout.fillHeight: true
text: qsTr("<h1>Stuff goes here</h1><p>this is just some sample text</p>")
}
}

您必须使用Shortcut
组件:
// ...
RowLayout {
id: row
width: parent.width
visible: false
Shortcut {
sequence: "Ctrl+F"
onActivated: {
row.visible = true
tf.focus = true
}
}
TextField {
id: tf
text: ""
placeholderText: qsTr("Search...")
selectByMouse: true
Layout.fillWidth: true
}
Button {
text: "x"
onClicked: row.visible = false
}
}
// ...
