qt - Set column width for QTableWidget in designtime

Question

I cannot find any information for the following question: is there a possibility to set width to columns for QTableWidget in designtime. When I opened ui-file in text editor, I found, that columns are declared like this:

<column>
    <property name="text" >
        <string>My column name</string>
    </property>
</column>

I tried to add some properties like width, but had no success.

The only question I found at qtcentre.org is this. But unfortunaly it is without an answer.

Thank you for advise (even if it would be "You can't").

P.S. Please, do not answer, that I can do it in runtime like this:

table->headerView()->resizeSection( columnIdx, width );

Answer 1

这是不可能的，至少在 Qt Designer 2.5.2 中是不可能的。Designer 仅提供一组有限的定制。

Answer 2

正如@UmNyobe 所说，设计师不可能，但你可以使用这个技巧至少在视觉上将宽度设置为你想要的。

将此代码添加到对话框的析构函数中，它将打印出每列的列宽，以及树小部件和对话框本身的宽度。

SettingsDialog::~SettingsDialog()
{
    QHeaderView *header = ui.treeWidget->header();
    for (int ii = 0; ii < header->count(); ++ii) {
        qDebug() << "column" << ii << ":" << header->sectionSize(ii);
    }
    qDebug() << "tree widget width: " << ui.treeWidget->width() << ", dialog width:" << width();
}

然后你可以运行你的程序，将列宽调整到你想要的，当你关闭对话框时，它会打印出你需要的宽度，如下所示：

第 0 列：110
第 1 栏：110
第 2 栏：110
第 3 栏：110
树小部件宽度：440，对话框宽度：543

这并不多，但总比在没有视觉反馈的情况下猜测哪些宽度看起来不错要好。
