我需要一个文本中有两种颜色的 QPushButton.我在 QTextDocument 中找到了一个带有 html 代码的解决方案,并且它正在运行.但是我需要居中对齐并且 html 代码不起作用.
I need a QPushButton with two colors in the text. I found a solution with a html code in QTextDocument and it's working. But I need center align and the html code isn't working.
QTextDocument Text;
Text.setHtml("<p align=center><font>Button</font><br/><font color=yellow>1</font></p>");
QPixmap pixmap(Text.size().width(), Text.size().height());
pixmap.fill( Qt::transparent );
QPainter painter(&pixmap);
Text.drawContents(&painter, pixmap.rect());
QIcon ButtonIcon(pixmap);
ui->toolButton->setText("");
ui->toolButton->setIcon(ButtonIcon);
ui->toolButton->setIconSize(pixmap.rect().size());
我明白了,
相同的代码 HTML 在 QLabel 中工作
The same code HTML is working in a QLabel
ui->label->setText("<p align=center><font>Label</font><br/><font color=yellow>1</font></p>");
有什么解决办法吗?
非常感谢.
你可以从QPushButton派生出来,通过paintEvent中的QPainter自己绘制文本.
You can derive from QPushButton and draw text yourself via QPainter in paintEvent.
class Button : public QPushButton
{
Q_OBJECT
public:
Button(QWidget *parent = 0)
: QPushButton(parent)
{ }
void paintEvent(QPaintEvent *p)
{
QPushButton::paintEvent(p);
QPainter paint(this);
paint.drawText(QPoint(10,10),"Hello");
}
};
