calc the normalized rectangle for a grid cell/获取网格单元格的归一化矩形

This method calculates the normalized coordinates for a specific grid cell based on the current layout parameters and grid configuration.

此方法根据当前布局参数和网格配置计算特定网格单元格的归一化坐标。

Parameters

rowCnt	Total number of rows in the grid / 网格总行数
colCnt	Total number of columns in the grid / 网格总列数
row	Grid row position (0-based) / 网格行位置（从0开始）
col	Grid column position (0-based) / 网格列位置（从0开始）
rowSpan	Number of rows to span (default: 1) / 跨行数（默认：1）
colSpan	Number of columns to span (default: 1) / 跨列数（默认：1）

Returns: Normalized coordinates [left, top, width, height] in range [0,1] 归一化坐标 [左, 上, 宽, 高]，范围 [0,1]

// Get the normalized rectangle for the top-left cell in a 2x2 grid
// 获取2x2网格中左上角单元格的归一化矩形
QRectF rect = layout->calcGridRect(2, 2, 0, 0);

// Get the normalized rectangle for a cell spanning two columns
// 获取跨两列的单元格的归一化矩形
QRectF rect = layout->calcGridRect(3, 3, 1, 0, 1, 2);

◆ calcNormRect()

QRectF QwtFigureLayout::calcNormRect	(	const QRect &	parentRect,
		const QRect &	rect
	)

static

Calculate normalized coordinates of rect relative to parentRect.

◆ setAxesNormPos()

void QwtFigureLayout::setAxesNormPos	(	QWidget *	widget,
		const QRectF &	rect
	)

Change the normalized position of an already added widget.

◆ widgetNormRect()

QRectF QwtFigureLayout::widgetNormRect ( QWidget * widget ) const

Get the normalized rectangle for a widget.
