我有一个页面有一个 Headers (PageTitle项目)和一个页脚(按钮),我没有找到一个更好的解决方案如何使一个项目(Flickable)填充所有窗口客户区(页眉和页脚之间的垂直空间)比计算其高度如下:
import QtQuick 2.7
import QtQuick.Controls 2.3
import QtQuick.Layouts 1.3
import QtQuick.Controls.Styles 1.4
import QtQml 2.2
Page {
id: root
background: Rectangle {
color: "transparent"
}
function close()
{
stack.pop()
root.destroy(1000)
}
function getText()
{
var params = scene.gameParams()
return qsTr("HowToPlay_Key").arg(params.lineLength).arg(params.newCount)
}
SystemPalette {
id: palette
}
GroupBox {
background: Rectangle {
color: palette.base
}
padding: 15
anchors.fill: parent
GridLayout {
rows: 3
columns: 1
flow: GridLayout.LeftToRight
width: parent.width
PageTitle {
id: title
Layout.fillWidth: true
text: qsTr("How to play")
}
Flickable {
//layout does not help
//Layout.fillWidth: true
Layout.fillHeight: true
//Layout.maximumHeight: root.height - (30 + 10 + title.height + closeButton.height)
//Using window here is a workaround, the other alternative on mobile in Screen.desktopAvailableWidth/Screen.desktopAvailableHeight
//Looks like root.width and window.height are zeros when the dialog is created from main's Component.onCompleted handler.
width: window.width - 30 - 30
//height: window.height - (30 + title.height + 10 + closeButton.height + 10 + 30)
flickableDirection: Flickable.VerticalFlick
TextArea.flickable: TextArea {
id: field
//height: 300
text: root.getText()
wrapMode: Label.Wrap
readOnly: true
}
ScrollBar.vertical: ScrollBar { }
}
Button {
id: closeButton
Layout.topMargin: 10
Layout.alignment: Qt.AlignRight
text: scene.firstRunFlag ? qsTr("Next") : qsTr("Close")
onClicked: close()
}
}
}
}
有没有更好的方法(不知道页眉和页脚高度),例如在WPF中,您可以轻松地创建3行网格并使第一行和第三行固定高度,第二行自动高度?
我尝试使用Layout.fillHeight,但得到以下(在360x640分辨率上):
页面看起来好像Flickable高度为零 .
有什么不对?

所有Flickable父元素都应该有
