【Qt開發】布局控件之間的間距設置

void QLayout::setContentsMargins ( int left, int top, int right, int bottom )

Sets the left, top, right, and bottom margins to use around the layout.

By default, QLayout uses the values provided by the style. On most platforms, the margin is 11 pixels in all directions.

This function was introduced in Qt 4.3.

 

這個說默認有11像素的間隙。

測試不行。

//hlayout->setContentsMargins(0,0,0,0);

//hlayout->setContentsMargins(QMargins(0,0,0,0));

 

主要通過setMargin(0) 設置Layout 的外部邊界為0

 

    hlayout->addWidget(start);

    hlayout->addWidget(settle);

    hlayout->addWidget(treatement);

    hlayout->addWidget(final);

    //hlayout->setStretchFactor(hlayout,0);

    hlayout->setMargin(0);

    //hlayout->setContentsMargins(0,0,0,0);

    //hlayout->setContentsMargins(QMargins(0,0,0,0));

    hlayout->setSpacing(0);

    //這個設置成功
