我正在设计一个聊天应用程序。
对于JTextPane
的聊天框,我使用了默认矩形以外的自定义形状,如第一张图片所示。但是当此JInternalFrame
窗口悬停在另一个窗口(JInternalFrame
)上时,自定义JTextPane
的边框线会显示拖动的线条,如第二张图片所示。
请问为什么会这样?
我所做的是将JTextpane
的边框设置为AbstractBorder
的子类。附加的是AbstractBorder
的子类。但是我注意到,当我删除graphic.setclip(area)
graphic.setclip(null)
块if(parent != null)
块下的paintBorder()

borderRegion.subtract(area);
g2.setClip(borderRegion);
g2.setColor(bg);
g2.fillRect(0, 0, width, height);
g2.setClip(null);
}
g2.setColor(color);
g2.setStroke(stroke);
g2.draw(area);
}
}
时,问题就消失了。
如何解决此问题,仍然有我喜欢的文本框?
hid = mat1[,1]
mat1 = mat1[,-1]
mat2 = mat2[,-1]
mat3 = matrix(0, nrow(mat1), ncol(mat1))
答案 0 :(得分:1)
您可以存储原始剪辑并将其设置回来
E.g。
Shape oldCLip=g2.getClip();
...your code here...
g2.setClip(oldClip);
剪辑不是矩形,但可以是自定义形状。当您将其设置为null时,您也会将其销毁为父级,因为Graphics实例从父级转到子级。所以你应该正确地恢复它。
