Set GridLayout row height in Vaadin
提问by
Very straight forward question, if you have a GridLayout defined in Vaadin, how can you set the height of all / individual rows? E.g:
非常直接的问题，如果您在 Vaadin 中定义了 GridLayout，您如何设置所有/单个行的高度？例如：
mainLayout = new GridLayout(2, 7);
mainLayout.setMargin(true);
mainLayout.setWidth("100%");
mainLayout.setHeight("100%");
// Set row[s] height?
Thanks in advance!
提前致谢！

I would rekommend you to read the following chapter in the book of vaadin.
It will explain how you set fullsize on grids and individual rows and how individual rows and columns can have different spacings.
它将解释如何在网格和单个行上设置 fullsize 以及单个行和列如何具有不同的间距。
Example from the book:
书中的例子：
GridLayout grid = new GridLayout(3,2);
// Layout containing relatively sized components must have
// a defined size, here is fixed size.
grid.setWidth("600px");
grid.setHeight("200px");
// Add some content
String labels [] = {
"Shrinking column<br/>Shrinking row",
"Expanding column (1:)<br/>Shrinking row",
"Expanding column (5:)<br/>Shrinking row",
"Shrinking column<br/>Expanding row",
"Expanding column (1:)<br/>Expanding row",
"Expanding column (5:)<br/>Expanding row"
};
for (int i=0; i<labels.length; i++) {
Label label = new Label(labels[i], Label.CONTENT_XHTML);
label.setWidth(null); // Set width as undefined
grid.addComponent(label);
}
// Set different expansion ratios for the two columns
grid.setColumnExpandRatio(1, 1);
grid.setColumnExpandRatio(2, 5);
// Set the bottom row to expand
grid.setRowExpandRatio(1, 1);
// Align and size the labels.
for (int col=0; col<grid.getColumns(); col++) {
for (int row=0; row<grid.getRows(); row++) {
Component c = grid.getComponent(col, row);
grid.setComponentAlignment(c, Alignment.TOP_CENTER);
// Make the labels high to illustrate the empty
// horizontal space.
if (col != 0 || row != 0)
c.setHeight("100%");
}
}
