How can I add a textbox so a user can enter numeric values into my form? I need the borders of the textbox control to be visible at a开发者_StackOverflow社区ll time.
Thanks.
You should implement your own class, inherited from TextBox and override void paint(Graphics g) method.
Smth, like that, sorry i write from mobile:
public void paint(Graphics g)
{
// set color
g.setColor(0x555555);
// draw 100*100 rectangle
g.drawRect(0, 0, 100, 100);
// dont forget to invoke
super.paint(g);
}
If you dont want use overriding, In OS 4.6+ you can use Border and BorderFactory classes (search in All Classes list).
// Each integer represents the amount of space between the box and border
// The four parameters of an XYEdge object represents each edge,
XYEdges thickPadding = new XYEdges(10, 10, 10, 10);
// Sample text field with a thick and solid rounded border
// and single solid colour background.
RichTextField simpleField = new RichTextField("Solid rounded border, solid background");
// Create border and background objects
Border roundedBorder = BorderFactory.createRoundedBorder(thickPadding, Border.STYLE_SOLID);
// Set the objects for use
simpleField.setBorder(roundedBorder);
// Add the field to the screen
add(simpleField);
