linux qt程序如何进行功能配置

Icon”就可以看到在各种平台设置Qt程序图标的方法。

Setting the Application Icon on Windows

First, create an ICO format bitmap file that contains the icon

image. This can be done with e.g. Microsoft Visual C++: Select

File|New, then select the File tab in the dialog that appears, and

choose Icon. (Note that you do not need to load your application

into Visual C++here we are only using the icon editor.)

Store the ICO file in your application’s source code directory,

for example, with the name myappico.ico. Then, create a text file

called, say, myapp.rc in which you put a single line of text:IDI_ICON1ICON

DISCARDABLE

"myappico.ico"Finally, assuming you are using qmake to generate

your makefiles, add this line to your myapp.pro file:

RC_FILE = myapp.rcRegenerate your makefile and your application.

The .exe file will now be represented with your icon inExplorer.

If you do not use qmake, the necessary steps are: first, run the

rc program on the .rc file, then link your application with the

resulting .res file.

*** 作如下：首先准备个ICO图标。例如：myappico.ico

用记事本新建个文件，里面就写一行：

IDI_ICON1 ICON DISCARDABLE “myappico.ico”

保存改名为 myapp.rc并把它和你的图标myappico.ico一起复制到你的QT工程项目的目录。

用记事本打开你的QT工程文件（如 “myapp.pro” ），在里面最后新添一行

保存，编译你的工程，成功了吧。

Profile是针对每个帐户的数据存储，比如一个电子商务网站的用户购物车数据。

“用户配置文件”是Profile这个词的直接翻译，其实没有文件的意思，默认存储在数据库中，不用自己管理文件。

Profile是HttpContext类的一个属性，是ProfileBase类，继承自SettingsBase类。

所谓Provider，是你可以定义Profile如何存储，默认是存储在LocalServer数据库中，需要网站重启动不丢失数据，所以不能存在内存中。

web.config中必须的Profile属性：什么叫必须？你如果不修改默认存储，只有每个Profile的name是必须的，如：

<profile defaultProvider="SqlProvider">//修改存储才需要

<providers>

<clear />

<add name="SqlProvider"

type="System.Web.Profile.SqlProfileProvider"

connectionStringName="SqlServices"

applicationName="SampleApplication"

description="SqlProfileProvider for SampleApplication" />

</providers>

<properties>

<add name="ZipCode" />//用户配置的项目才是必须的

<add name="CityAndState" />

</properties>

</profile>

</system.web>

tar zxvf qt-everywhere-opensource-src-4.8.4.tar.gz

进入解压后文件目录，执行配置

root@emouse:~/study# cd qt-everywhere-opensource-src-4.8.4/

root@emouse:~/study/qt-everywhere-opensource-src-4.8.4# ./configure

修改配置文件

if [ -z "$QT_INSTALL_PREFIX" ]then

if [ "$CFG_DEV" = "yes" ]then

QT_INSTALL_PREFIX="$outpath" # In Development, we use sandboxed builds by default

elif [ "$PLATFORM_QWS" = "yes" -o "$PLATFORM_QPA" = "yes" ]then

if [ "$PLATFORM_QPA" = "yes" ]then

QT_INSTALL_PREFIX="/usr/local/Trolltech/QtLighthouse-${QT_VERSION}"

else

QT_INSTALL_PREFIX="/usr/local/Trolltech/QtEmbedded-${QT_VERSION}"

fi

if [ "$PLATFORM" != "$XPLATFORM" ]then

QT_INSTALL_PREFIX="${QT_INSTALL_PREFIX}-${CFG_ARCH}"

fi

elif [ -d "$EPOCROOT" ] &&[ "$XPLATFORM_SYMBIAN" = "yes" ]then

if [ "$XPLATFORM_SYMBIAN" = "yes" ]then

QT_INSTALL_PREFIX="$EPOCROOT/epoc32/"

QT_INSTALL_LIBS="$EPOCROOT/epoc32/release/armv5/lib/"

fi

else

QT_INSTALL_PREFIX="/usr/local/Trolltech/Qt-${QT_VERSION}"

ok

启动

/usr/local/Trolltech/Qt-4.8.4/bin/designer
