It is possible specify values that lie outside the bounding box (-0.6 or 1.8, for instance). 警告: The stops have to appear sorted in ascending order. 范例: /* linear gradient from white to green */ QTextEdit { background: qlineargradient(x1:0, y1:0, x2:1, y2:1, stop:0 white, stop: 0.4 gray, stop:1 green) } /* linear gradient from white to green */ QTextEdit { background: qlineargradient(x1:0, y1:0, x2:1, y2:1, stop:0 white, stop: 0.4 rgba(10, 20, 30, 40), stop:1 rgb(0, 200, 230, 200)) } /* conical gradient from white to green */ QTextEdit { background: qconicalgradient(cx:0.5, cy:0.5, angle:30, stop:0 white, stop:1 #00FF00) } /* radial gradient from white to green */ QTextEdit { background: qradialgradient(cx:0, cy:0, radius: 1, fx:0.5, fy:0.5, stop:0 white, stop:1 green) } |
