问题

  1. QProgressBar *b = new QProgressBar();
  3. QString progressStyle = QString("::chunk {"
  4.                                     "background-color: green;"
  5.                                     "}");
  7. b->setStyleSheet(progressStyle);
  9. b->setValue(80);
  10. b->show();

  6.                                     "stop: 0 green, stop: 0.6 green, "
  7.                                     "stop: 0.6 orange, stop: 0.8 orange, "
  8.                                     "stop: 0.8 transparent, stop: 1 transparent"
  9.                                     ")}");
  11. b->setStyleSheet(progressStyle);
  13. b->setValue(80);
  14. b->show();

I'm trying to use solid colors, each color separated from the other, but my code results in gradient colors.

Here's how it looks:

How can I avoid this gradient effect, and achieve the solid colors I need?

得分: 0

尝试添加 0.0001，以避免颜色范围重叠，从而产生渐变效果。

纯色：

  1. "stop: 0 绿色, stop: 0.6 绿色, "
  2. "stop: 0.60001 橙色, stop: 0.8 橙色, "
  3. "stop: 0.80001 红色, stop: 1 红色"

渐变：

  1. "stop: 0 绿色, stop: 0.6 绿色, "
  2. "stop: 0.6 橙色, stop: 0.8 橙色, "
  3. "stop: 0.8 红色, stop: 1 红色"
英文:

Try adding 0.0001, to avoid color ranges from overlapping, which causes the gradient effect.

Solid colors:

  1. "stop: 0 green, stop: 0.6 green, "
  2. "stop: 0.60001 orange, stop: 0.8 orange, "
  3. "stop: 0.80001 red, stop: 1 red"

Gradient:

  1. "stop: 0 green, stop: 0.6 green, "
  2. "stop: 0.6 orange, stop: 0.8 orange, "
  3. "stop: 0.8 red, stop: 1 red"
