我有一个TextField，我想将其限制为几个键，如果单击该键，它将在TextField上放置一个特定的值，但是我仍然希望{{1 }}和tab键起作用，如果我单击这两个键中的任何一个，则焦点应移至下一个控件。
该限制enter的代码为：
TextField完整的示例：
TextField {
height: 479.9
Layout.fillWidth: true
Layout.rightMargin: 10
maximumLength: 5
Keys.onPressed: {
var c
switch (event.key) {
case Qt.Key_Up:
c = String.fromCharCode(0x25B2)
break
case Qt.Key_Down:
c = String.fromCharCode(0x25BC)
break
case Qt.Key_Right:
c = String.fromCharCode(0x25B6)
break
default:
event.accepted = true
break
}
if (!event.accepted) {
var s = text.concat(c)
text = s.substr(Math.max(0,s.length-maximumLength), maximumLength)
event.accepted = true
}
}
onFocusChanged: if(focus) { configScroll.scrollToY(y); }
}
那么，为了使import QtQuick 2.9
import QtQuick.Controls 2.2
import QtQuick.Layouts 1.3
ApplicationWindow {
id: window
title: "Stack"
visible: true
width: 1400
Page {
id: page
anchors.fill: parent
property int responsiveWidth: 1000
property int maximumWidth: 900
ScrollView {
anchors.fill: parent
function scrollToY(y) { //TODO: Não funciona com import QtQuick.Controls 1.4
configScroll.flickableItem.contentY = y-30
}
GridLayout {
columns: 2
Keys.onPressed: {
if(event.key==Qt.Key_Return)
for (var i = 0; i < children.length; ++i)
if (children[i].focus) {
children[i].nextItemInFocusChain().forceActiveFocus()
break
}
}
width: page.width > page.responsiveWidth ? page.maximumWidth : page.width
anchors.top: parent.top
anchors.left: parent.left
anchors.leftMargin: page.width > page.responsiveWidth ? (page.width - childrenRect.width)/2 : 10
anchors.rightMargin: page.width > page.responsiveWidth ? 0 : 10
Label {
text: "Company Name"
color: "red"
Layout.fillWidth: true
}
TextField {
objectName: "company_name"
font.bold: true
Layout.fillWidth: true
Layout.rightMargin: 10
onFocusChanged: if(focus) { configScroll.scrollToY(y); }
}
Label {
text: "test"
color: "red"
Layout.fillWidth: true
}
TextField {
height: 479.9
Layout.fillWidth: true
Layout.rightMargin: 10
maximumLength: 5
Keys.onPressed: {
var c
switch (event.key) {
case Qt.Key_Up:
c = String.fromCharCode(0x25B2)
break
case Qt.Key_Down:
c = String.fromCharCode(0x25BC)
break
case Qt.Key_Right:
c = String.fromCharCode(0x25B6)
break
default:
event.accepted = true
break
}
if (!event.accepted) {
var s = text.concat(c)
text = s.substr(Math.max(0,s.length-maximumLength), maximumLength)
event.accepted = true
}
}
onFocusChanged: if(focus) { configScroll.scrollToY(y); }
}
Label {
text: "label"
color: "red"
Layout.fillWidth: true
}
TextField {
objectName: "company_name"
font.bold: true
Layout.fillWidth: true
Layout.rightMargin: 10
onFocusChanged: if(focus) { configScroll.scrollToY(y); }
}
}
}
}
}
和TextField重新工作，我需要对tab进行哪些更改？
