我正在向 QList 小部件添加一个字符串列表，如下所示：

myList.addItems( [ 'item1' , 'item2' , 'item3' ] )

默认情况下，列表将它们与左侧对齐，但我想将它们放在列表的中心。

有任何想法吗？

我已将页脚添加到EasyCareBath.com,我可以让div正常工作,除了".footer_box",它不会居中.我添加了"left:15%",当你把窗户向上吹时,它就不再对齐了.我错过了什么或者我对css做了太多的事吗？

.footer_spacer {
    height: 50px;   
}
.footer_wrapper {
    height: 375px;
    background-color: #e6dccb;
}
.footer {
    border-top: 10px solid #789E65;
    box-shadow: 0 5px 20px rgba(0, 0, 0, 0.6);
    margin-top: 0px;
    /*min-width: 1007px;*/
    height: 235px;
    background-attachment: scroll;
    background-image: url(../images_footer/footer_bg.png);
    background-repeat: repeat-x;
    background-position: center top;
    position: relative;
}
.footer_box {
    height: 236px;
    width: 1007px;
    /*position: relative;*/
}
.footer_copyright {
    width: 100%;
    /* [disabled]height: 100px; */
    /*float: left;*/
    padding-top: 15px;
    position: relative;
    text-align: center;
    word-spacing: normal;
    font-family: Arial, Helvetica, sans-serif;
    font-size: 14px; …

这就是我想要完成的事情:

|---------| |----------|
| TableC1 | | TableC2  |
|---------| |----------|
     |------------|
     | TableC3    |
     |------------|

您可以在上面看到的是我想要完成的任务.TableCell1和TableCell2很好地对齐在表的中心,但由于我想在它们下面只有一个表格单元格,所以TableCell3只是去了一个边,左边或右边并不重要.

这是我写的方式的片段:

HTML:

<table id = "some-boxes">

<tr>
<td id = "first-box">
SOME TEXT101
</td>

<td id = "second-box">
SOME TEXT202
</td>
</tr>

<td id = "third-box">
SOME TEXT303
</td>
</table

CSS:

#first-box{
   width: 100px;
}
#second-box{
   width: 100px;
}
#third-box{
   width: 200px;
   text-align: center;
   margin-left: 50%;
   margin-left: 50%;
}

希望有人能回答我的这个谜团.谢谢你的问候:)

我有一些CSS的小问题 - > jsFiddle的例子

简单按钮:

<button type="reset" id="reset-btn">Reset</button>

CSS规则:

button#reset-btn:after{
    content:" <<";
    font-size:2em;
}

正如您所看到的,"<<"是通过CSS生成的.有没有办法将这两种不同的字体大小相互对齐,以便较大的"<<"旁边的文字位于按钮的垂直中心？

提前致谢!

<DockPanel Grid.Row="1" HorizontalAlignment="Right" Width="300">
    <Button x:Name="startPackageSendButton" Command="{Binding StartPackageSendingProcessCommand}"  Style="{StaticResource blueButtonStyle}" Content="Start" Width="100" VerticalAlignment="Top" Margin="0,0,0,0" Visibility="Visible" HorizontalAlignment="Right"/>
    <Button x:Name="clearPackageSendButton" Command="{Binding ClearPackageSendingProcessCommand}"  Style="{StaticResource blueButtonStyle}" Content="Clear" Width="100" VerticalAlignment="Top" Margin="0,0,0,0" Visibility="Collapsed" HorizontalAlignment="Right"/>

</DockPanel>

我正在使用Dockpanel水平对齐堆叠一些按钮。如果某些按钮不是，Visible我在按钮之间有空格。

如果按钮未Visibility设置为可见，我如何消除空格？有什么技术可以达到这种效果吗？

编辑：我按照建议将隐藏更改为折叠。

我正在阅读一个二进制文件,我知道它的结构,我试图放入一个结构但是当我来读取二进制文件时,我发现当它单独打印出结构时,它似乎正确但是然后在第四次阅读时,它似乎将它添加到上次读取的最后一个成员.

这里的代码可能比我解释它更有意义:

STRUC

#pragma pack(push, r1, 1)
struct header
{
    char headers[13];
    unsigned int number;
    char date[19];
    char fws[16];
    char collectversion[12];
    unsigned int seiral;
    char gain[12];
    char padding[16];

};

主要

  header head;
  int index = 0;
  fstream data;
  data.open(argv[1], ios::in | ios::binary);
  if(data.fail())
    {
      cout << "Unable to open the data file!!!" << endl;
      cout << "It looks Like Someone Has Deleted the file!"<<endl<<endl<<endl;
      return 0;

    }
   //check the size of head
   cout << "Size:" << endl;
   cout << sizeof(head) …

这是一个例子,我从以前的SO问题略有改变:http: //jsfiddle.net/tPjQR/72/

ol {
    font-family: Georgia, serif;
}
ol span {
    font-family: Arial, sans-serif;
    font-size: 17px
}

<ol>
    <li><span>Entry one</span></li>
    <li><span>Entry two</span></li>
    <li><span>Entrye three</span></li>
    <li><span>Entry five</span></li>
    <li><span>Entry six</span></li>
    <li><span>Entry Long Long Long Long Long Long Long Long Long Long Long Long Long Long Long Long Long</span></li>
</ol>

我想排列这些列,这样,无论一列中有多少文本,每列的第一个字符都会排成一行.

例如

不

Entry one
Entry two
Entrye three
Entry five
Entry six

宁

Entry  one
Entry  two
Entrye three
Entry  five
Entry  six

有没有办法用列表项执行此操作,还是需要使用表？

考虑这个例子:

class A
{
public:
     int a;
public:
     A():a(1){};
};

class B:public A
{
public:
     int b;
public:
     B():b(2){};
};

void print(A* a)
{
     for(int i=0; i<10; ++i)
     {
          cout<<a[i].a<<" ";
     } 
}

int main()
{
     B b[10];
     print(b);
}

我的程序输出是:1 2 1 2 1 2 1 2 1 2 1 2. 但它如何通过[i] .a访问数据b,因为我从未在输出中提到过b.

有以下结构：

typedef struct {
    uint8_t val1;
    uint16_t val2;
}some_config_type;

some_config_type EEMEM config = {
    .val1 = 20,
    .val2 = 2000
};

该配置存储在eeprom内存中，我想从中加载它。我不确定avr gcc或C中是否有共同的规则，当我使用eeprom_read_block复制到另一个内存部分ram时，它保证了bot结构的布局是相同的。我想确保这在任何情况下都不会中断，并且内存布局是相同的，而不取决于部分。
