Set GridLayout row height in Vaadin

问题

Very straight forward question, if you have a GridLayout defined in Vaadin, how can you set the height of all / individual rows? E.g:

mainLayout = new GridLayout(2, 7);
mainLayout.setMargin(true);
mainLayout.setWidth("100%");
mainLayout.setHeight("100%");
// Set row[s] height?

Thanks in advance!

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.

Example from the book:

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%");
    }
}
