What is the method for adjusting the height of a CustomScrollPanel to be 100%?

I'm trying to set a CustomScrollPanel to have a height of 100%, but I'm having trouble making it work. Here's what I've attempted:

public class MyScrollPanel extends Composite implements HasWidgets {

private ResizeLayoutPanel resizeLayoutPanel;
private CustomScrollPanel customScrollPanel;

public MyScrollPanel() {
    resizeLayoutPanel = new ResizeLayoutPanel();
    resizeLayoutPanel.setStyleName(resources.css().resizeLayoutPanel());
    customScrollPanel = new CustomScrollPanel();
    customScrollPanel.addStyleName(resources.css().customScrollPanel());

    resizeLayoutPanel.add(customScrollPanel);
    initWidget(resizeLayoutPanel);
}

This is my CSS snippet: 

.resizeLayoutPanel {
   height: 100%;
   background-color: yellow;    
}

Any suggestions on how to make the CustomScrollPanel fill the whole height?

Answer №1

Using <strong>height:100%</strong> may not produce the desired result unless there is a specified height for the parent div, such as <strong>height:500px</strong>.

To ensure proper height adjustment, it is recommended to dynamically calculate the window or parent container's height and assign that value to your div element, implementing a resize function for real-time adjustments.

Answer №2

When utilizing ScrollPanel, it is important to note that it implements RequiresResize and will obtain its size from the parent widget if the parent also implements ProvidesResize. Therefore, if the parent widget occupies 100% of the vertical space, the ScrollPanel will adjust accordingly to occupy the same amount of space.
