Detailed Description
Rectangle items are used to fill areas with solid color or gradients and to provide a rectangular border.
Each Rectangle item is painted using either a solid fill color, specified using the fillColor property, or a gradient, defined using one of the ShapeGradient subtypes and set using the gradient property. If both a color and a gradient are specified, the gradient is used.
An optional border can be added to a rectangle with its own color and thickness by setting the strokeColor and strokeWidth properties. Setting the color to transparent creates a border without a fill color.
Rounded rectangles can be drawn using the radius property. The radius can also be specified separately for each corner. Because this introduces curved edges to the corners of a rectangle. Additionally, bevel can be applied on any corner to cut it off sharply.
Example Usage
You can use the Rectangle component in Qt Design Studio to create different kinds of rectangles.
The QML code looks as follows:
RectangleItem {
id: rectangle1
x: 480
y: 164
width: 409
height: 307
radius: 0
gradient: RadialGradient {
GradientStop {
position: 0
color: "#cea1f9fc"
}
GradientStop {
position: 1
color: "#ec7d7d"
}
focalY: rectangle1.height * 0.5
focalX: rectangle1.width * 0.5
focalRadius: Math.min(rectangle1.width, rectangle1.height) * 0
centerY: rectangle1.height * 0.5
centerX: rectangle1.width * 0.5
centerRadius: Math.min(rectangle1.width, rectangle1.height) * 0.5
}
strokeWidth: 6
strokeColor: "#ff0000"
bottomLeftRadius: 30
topRightRadius: 30
adjustBorderRadius: true
}
RectangleItem {
id: rectangle2
x: 954
y: 164
width: 409
height: 307
radius: 0
fillColor: "#c062606a"
strokeWidth: -1
topRightRadius: 30
strokeColor: "#8b8a8a"
bottomLeftRadius: 30
adjustBorderRadius: true
}
RectangleItem {
id: rectangle3
x: 480
y: 533
width: 409
height: 307
radius: 0
gradient: LinearGradient {
y2: rectangle3.height * 1
y1: rectangle3.height * 0
x2: rectangle3.width * 1
x1: rectangle3.width * 0
GradientStop {
position: 0.10526
color: "#e77979"
}
GradientStop {
position: 0.67105
color: "#716767"
}
}
topRightBevel: true
topRightRadius: 30
strokeWidth: 6
strokeColor: "#ff0000"
bottomLeftRadius: 0
adjustBorderRadius: true
}
RectangleItem {
id: rectangle4
x: 954
y: 533
width: 409
height: 307
radius: 30
fillColor: "#d87c7c"
borderMode: 2
dashOffset: 3
joinStyle: 2
strokeStyle: 5
topRightBevel: false
strokeWidth: 6
strokeColor: "#ff0000"
adjustBorderRadius: true
}Property Documentation
adjustBorderRadius : bool |
It defines how the border radius is calculated for the corners.
bevel : bool |
Whether the rectangle corner is beveled.
borderMode : int |
It defines where the border is drawn.
| Constant | Description |
|---|---|
Border.Inside | The border is drawn along the inside edge of the item and does not affect the item width. This is the default value. |
Border.Middle | The border is drawn over the edge of the item and does not affect the item width. |
Border.Outside | The border is drawn along the outside edge of the item and increases the item width by the value of strokeWidth. |
The default value is 0, which sets the border along the inside edge of the Item.
See also strokeWidth.
bottomLeftRadius : int |
The radius of the bottom left rectangle corner.
bottomRightRadius : int |
The radius of the bottom right rectangle corner.
capStyle : int |
The cap style defines how the end points of lines are drawn using QPainter. The cap style only applies to lines with width 1 or greater. The cap style can be square, flat, or round.
The default is Qt::SquareCap
See also QPen::capStyle().
dashOffset : alias |
The starting point of the dash pattern for the rectangle border.
The offset is measured in terms of the units used to specify the dash pattern. For example, a pattern where each stroke is four units long, followed by a gap of two units, will begin with the stroke when drawn as a line. However, if the dash offset is set to 4.0, any line drawn will begin with the gap. Values of the offset up to 4.0 will cause part of the stroke to be drawn first, and values of the offset between 4.0 and 6.0 will cause the line to begin with part of the gap.
The default value is 0.
See also QPen::setDashOffset().
dashPattern : alias |
The dash pattern of the rectangle border specified as the dashes and the gaps between them.
The dash pattern is specified in units of the pen's width. That is, a dash with the length 5 and width 10 is 50 pixels long.
Each dash is also subject to cap styles, and therefore a dash of 1 with square cap set will extend 0.5 pixels out in each direction resulting in a total width of 2.
The default value is (4, 2), meaning a dash of 4 * strokeWidth pixels followed by a space of 2 * strokeWidth pixels.
See also QPen::setDashPattern().
fillColor : alias |
The rectangle fill color.
A rectangle can be filled with a solid color or with any of the linear, radial, or conical gradients.
When set to transparent, no filling occurs.
The default value is white.
gradient : ShapeGradient |
The gradient of the rectangle fill color.
By default, no gradient is enabled and the value is null. In this case, the fill uses a solid color based on the value of fillColor.
When set, fillColor is ignored and filling is done using one of the ShapeGradient subtypes.
joinStyle : int |
The join style is used to connect two border line segments.
| Constant | Description |
|---|---|
ShapePath.MiterJoin | The outer edges of the lines are extended to meet at an angle, and this area is filled. |
ShapePath.BevelJoin | The triangular notch between the two lines is filled. This is the default value. |
ShapePath.RoundJoin | A circular arc between the two lines is filled. |
See also Qt::PenJoinStyle.
radius : int |
The radius used to draw rounded corners. The default value is 10. If radius is non-zero, the corners will be rounded, otherwise they will be sharp.
If radius is non-zero, the corners will be rounded, otherwise they will be sharp. The radius can also be specified separately for each corner by using the bottomLeftRadius, bottomRightRadius, topLeftRadius, and topRightRadius properties.
strokeColor : alias |
The color used to draw the border of the rectangle. When set to transparent, no line is drawn. The default value is red.
See also QColor.
strokeStyle : int |
The style of the rectangle stroke.
When set to None, no stroke is drawn.
The stroke can be set to have a Solid, Dash, Dot, Dash Dot, or Dash Dot Dot pattern.
The default value is Solid.
strokeWidth : alias |
The width of the border of the rectangle. The default value is 4. A width of 1 creates a thin line. For no line, use a negative value or a transparent color.
Note: The width of the rectangle's border does not affect the geometry of the rectangle itself or its position relative to other items if anchors are used.
The border is rendered within the rectangle's boundaries.
topLeftRadius : int |
The radius of the top left rectangle corner.
topRightRadius : int |
The radius of the top right rectangle corner.
