我的QML ApplicationWindow名为ueWindowMain，并在main.qml中声明。其中包含名为StatusBar的QML ueStatusBar，其中包含两个名为ueStatusIndicatorDatabaseConnected和ueStatusIndicatorBluetoothPrinterConnected的图标，显示一些状态和一个可检查的QML Button，名为{{1} }}：
ueStaffSelector现在，import QtQuick 2.4
import QtQuick.Controls 1.3
import QtQuick.Window 2.2
import QtQuick.Dialogs 1.2
import QtQuick.Layouts 1.0
import QtQuick.Controls.Styles 1.4
import si.mikroelektronika 1.0
import "gui/items"

Layout.maximumWidth: 96
Layout.fillHeight: true
ueParamImageStatusOn: "qrc:///ueIcons/icons/ueDbConnectionOk.png"
ueParamImageStatusOff: "qrc:///ueIcons/icons/ueDbConnectionError.png"
} // ueStatusIndicatorDatabaseConnected
UeBluetoothStatusIndicator
{
id: ueStatusIndicatorBluetoothPrinterConnected
Layout.minimumWidth: 96
Layout.preferredWidth: 96
Layout.maximumWidth: 96
Layout.fillHeight: true
ueParamImageStatusOn: "qrc:///ueIcons/icons/ueBtConnectionOk.png"
ueParamImageStatusOff: "qrc:///ueIcons/icons/ueBtConnectionError.png"
} // ueStatusIndicatorBluetoothPrinterConnected
UeStaffSelector
{
id: ueStaffSelector
Layout.minimumWidth: 96
Layout.preferredWidth: 96
Layout.maximumWidth: 96
Layout.fillHeight: true
} // ueStaffSelector
} // RowLayout
} // ueStatusBar
} // ueWindowMain
中的这三个项目使用StatusBar定位。如何在QML代码中计算它们的坐标，即以编程方式计算？
答案 0 :(得分：0)
我设法通过以下代码块来解决问题：
x: ueStatusIndicatorDatabaseConnected.width+
ueStatusIndicatorBluetoothPrinterConnected.width+2*ueStatusBarLayout.spacing
y: ueWindowMain.height-ueStatusBar.height-ueStaffView.height
现在它似乎工作正常。
