I worked on making an EditField autosize according to the MaxSize value and paint rectangle around:
the following code works fine inline:
EditField EF = new EditField("",null,8,EditField.FILTER_REAL_NUMERIC){
public void layout(int width, int height){
int x = getFont().getAdvance("0") * getMaxSize();
super.layout(x,getPreferredHeight());
setExtent(x,getPreferredHeight());
} protected void paint(Graphics g) {
g.setColor(Color.GRAY);g.drawRect(0,0,getWidth(),getHeight());
g.setColor(Color.BLACK);
super.paint(g); }
};
but when i build a class to extend EditField, it doesn't work well (the width is not set right)
public class SizeableEditField extends EditField {
public SizeableEditField(){
new EditField();}
public SizeableEditField(long style){
new EditField(style);}
public SizeableEditField(String label, String initialValue){
new EditField(label, initialValue);}
public SizeableEditField(String label, String initialValue,int maxNumChars, long style) {
new EditField(label, initialValue, maxNumChars, style); }
public void layout(int width, int height){
int x = this.getFont().getAdvance("0") * this.getMaxSize(); /*get the size of the field in pixels from maxChar*/
super.layout(x,this.getPreferredHeight()); /*layout with that max space in mind */
setExtent(x,this.getPreferredHeight()); /*set extend of the field for manager*/
}
protected void paint(Graphics g) {
g.setColor(Color.GRAY);g.drawRect(0,0,this.getWidth(),this.getHeight());g.setColor(Color.
BLACK); super.paint(g); }
}
calling with:
SizeableEditField EF = new SizeableEditField("",null,8,EditField.FILTER_REAL_NUMERIC);
The rectangle is painted but the size is still the fullwidth, so it seems like x is not calculated right.
Any idea why? My debugger doesn't let me see Expression results, os it is hard to figure out.
Thanks for help.
Regards
