Question

我正在尝试在诺基亚N9上使用PySide和QML，出于某种原因，我的测试应用程序看起来与本机N9应用程序不同。例如，在这里我得到一个双重状态栏（它们都对敲击做出反应）。

Double status bar

以下是此代码：

main.py

import sys

from PySide.QtCore import *
from PySide.QtGui import *
from PySide.QtDeclarative import *

app = QApplication(sys.argv)
view = QDeclarativeView()
view.setResizeMode(QDeclarativeView.SizeViewToRootObject)
view.setSource('main.qml')
view.window().show()
app.exec_()

和QML文件：

main.qml

import QtQuick 1.1
import com.nokia.meego 1.1 

PageStackWindow {
  Component.onCompleted: {
    var pageComponent = Qt.createComponent("PageX.qml")
    pageStack.push(pageComponent)
  }
}

PageX.qml

import QtQuick 1.1
import com.nokia.meego 1.1

Page {
  id: pageOne
  Text {
    text: "Hello, this is page one"
  }
}

文件main.qml会创建PageStackWindow，我怀疑是...Window部分会让手机再次呈现状态栏，就像它会尝试为每个窗口添加状态栏一样创建（在这里，也许我们在窗口内有一个窗口？）。此外，窗口和工具栏之间还有一个空格。有人能指出这样做的正确方法吗？我只想在PageStack中使用普通的页面。

Answer 1

您可以尝试＆＃34; showStatusBar：false＆＃34;。我在Qt Simulator上尝试了你的例子，它没有状态栏。我有一个Meego-QML-PySide应用程序，QML应用程序在Qt Simulator上没有状态栏。但是当我用Necessitas在android上试用它时，我遇到了同样的问题。在我使用＆＃34; showStatusBar：false＆＃34;问题解决了。谢谢，在我看到你的问题之后，我第一次在Android上运行我的QML-Meego应用程序：）

PageStackWindow {
  showStatusBar : false
  Component.onCompleted: {
    var pageComponent = Qt.createComponent("PageX.qml")
    pageStack.push(pageComponent)
  }
}

抱歉，我是QML的新手。您可以尝试使用不同的QML Harmattan示例，并使用此view.window().showFullScreen()我的应用程序包括ListView再次使用python，并基于Nokia Harmattan开发人员文档站点的示例应用程序。首先这是Android的main.py：

#!/usr/bin/env python

# A simple PySide example

import sys
import os
import traceback

# log to file on Android

LOG_FOLDER = '/sdcard/'
fSock = open(os.path.join(LOG_FOLDER, 'pyside_example_log.txt'), 'w', 1)
rfSock = open(os.path.join(LOG_FOLDER, 'pyside_example_error_log.txt'), 'w', 1)
sys.stdout = fSock
sys.stderr = rfSock

print("** stdout diverted to file **")

# for some reason, the PySide bindings can't find the libshiboken.so and libshiboken,
# even though they are in a directory in LD_LIBRARY_PATH, resulting in errors like this:
#
# ImportError: Cannot load library: link_image[1965]:   157 could not load needed library
# 'libshiboken.so' for 'QtCore.so' (load_library[1120]: Library 'libshiboken.so' not found)
#
# if both are loaded to memory manually with ctypes, everything works fine
print('manual libshiboken.so and libpyside.so loading')
from ctypes import *
#PROJECT_FOLDER = '/data/data/org.modrana.PySideExample'

PROJECT_FOLDER = os.environ['PYSIDE_APPLICATION_FOLDER']
LIB_DIR = os.path.join(PROJECT_FOLDER, 'files/python/lib')
SHIBOKEN_SO = os.path.join(LIB_DIR, 'libshiboken.so')
PYSIDE_SO = os.path.join(LIB_DIR, 'libpyside.so')
print("path to libshiboken and libpyside:")
print(SHIBOKEN_SO)
print(PYSIDE_SO)
shibok = CDLL(SHIBOKEN_SO)
psde = CDLL(PYSIDE_SO)
print("manual loading done")

print("importing PySide")

和QML代码：
