- The
<mx:Grid>tag defines a Grid container. - The
<mx:GridRow>tag defines a grid row, which has one or more cells. The grid row must be a child of the<Grid>tag. - The
<mx:GridItem>tag defines a grid cell, and must be a child of the<GridRow>tag. The<mx:GridItem>tag can contain any number of children.
The height of all the cells in a single row is the same, but each row can have a different height. The width of all cells in a single column is the same, but each column can have a different width. You can define a different number of cells for each row or each column of the Grid container. In addition, a cell can span multiple columns or multiple rows of the container.
The Grid, GridRow, and GridItem containers have the following default sizing characteristics:
| Characteristic | Description |
|---|---|
| Grid height | The sum of the default or explicit heights of all rows plus the gaps between rows. |
| Grid width | The sum of the default or explicit width of all columns plus the gaps between columns. |
| Height of each row and each cell | The default or explicit height of the tallest item in the row. If a GridItem container does not have an explicit size, its default height is the default or explicit height of the child in the cell. |
| Width of each column and each cell | The default or explicit width of the widest item in the column. If a GridItem container does not have an explicit width, its default width is the default or explicit width of the child in the cell. |
| Gap between rows and columns | Determined by the horizontalGap and verticalGap styles of the Grid class. The default value for both gaps is 6 pixels. |
| Default padding | 0 pixels for the top, bottom, left, and right values, for all three container classes. |

Descrizione della funzione di costruzione
Grid | () | Funzione di costruzione |
public function Grid()| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
Constructor.
Descrizione dei metodi
measure | () | metodo |
override protected function measure():void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
Calculates the preferred, minimum, and maximum sizes of the Grid.
You should not call this method directly; it is an advanced
method for use in subclassing.
The Flex LayoutManger calls the measure() method
at the appropriate time.
At application startup, the Flex LayoutManager attempts
to measure all components from the children to the parents
before setting them to their final sizes.
To understand how the Grid container calculates its measurements,
assume that every GridItem container has its rowSpan
property and colSpan property set to 1.
The measured width of the first column of the Grid container
is equal to the maximum among of the measured widths
of all GridItem containers in the first column.
Similarly, the measured width of the second column is
the maximum of all measured widths among the GridItem containers
in the second column, and so on.
The measuredWidth of the entire Grid container
is the sum of all columns' measured widths, plus the thickness
of the border, plus the left and right padding, plus room
for the horizontal gap between adjacent grid cells.
The measuredHeight, minWidth,
minHeight, maxWidth, and
maxHeight properties' values are all calculated
in a similar manner, by adding together the values of the
GridItem containers' measuredHeight properties,
minWidth properties, and so on.
If a GridItem container's colSpan property is 3,
that GridItem container's measuredWidth is divided
among 3 columns.
If the measuredWidth is divided equally,
each of the three columns calculates its measured width
as if the GridItem container were only in that column
and the GridItem container's measuredWidth
were one-third of its actual value.
However, the GridItem container's measuredWidth
property is not always divided equally among all the columns it spans.
If some of the columns have a property with a percentage value
of width, the GridItem container's
measuredWidth property is divided accordingly,
attempting to give each column the requested percentage
of the Grid container.
All of the values described previously are the measured widths and heights of Grid. The user can override the measured values by explicitly supplying a value for the following properties:
minHeightminWidthmaxHeightmaxWidthheightwidth
If you override this method, your implementation must call the
super.measure() method or set the
measuredHeight and measuredWidth properties.
You may also optionally set the following properties:
measuredMinWidthmeasuredMinHeight
These properties correspond to the layout properties listed previously and, therefore, are not documented separately.
updateDisplayList | () | metodo |
override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
Sets the size and position of each child of the Grid.
You should not call this method directly; it is an advanced
method for use in subclassing.
The Flex LayoutManager calls the updateDisplayList
method at the appropriate time.
At application startup, the Flex LayoutManager calls
the updateDisplayList() method on every component,
starting with the root and working downward.
The Grid container follows the same layout rules as the VBox container. The positions and sizes of the GridRow containers are calculated the same way that a VBox container determines the positions and sizes of its children. Similarly, a GridRow container positions its GridItem containers using a similar layout algorithm of an HBox container.
The only difference is that the GridRow containers all coordinate with one another, so they all choose the same positions and sizes for their children (so that the columns of the Grid container align).
If you override this method, your implementation should call
the super.updateDisplayList() method
and call the move() and the setActualSize()
methods on each of the children.
For the purposes of performing layout, you should get the size
of this container from the unscaledWidth
and unscaledHeight properties, not the
width and height properties.
The width and height properties do not
take into account the values of the scaleX
and scaleY properties for this container.
Parametri
unscaledWidth:Number — Specifies the width of the component, in pixels,
in the component's coordinates, regardless of the value of the
scaleX property of the component.
| |
unscaledHeight:Number — Specifies the height of the component, in pixels,
in the component's coordinates, regardless of the value of the
scaleY property of the component.
