Now we continue on the existing procedures:

Protected Static Imageicon CreateImageicon (String Path,
String description) {
Java.net.url imgurl = Celsiusconverter2.class.getResource (PATH);
IF (imgurl! = null) {
Return New Imageicon (Imgurl, Description);
} else {
System.err.Println ("COULDN't Find File: PATH);
Return NULL;
}
}
Private static void createandshowgui () {
Jframe.SetDefault (TRUE);
Celsiusconvert2 Converter = New CelsiusConverter2 ();
}
Public static void main (String [] args) {
Javax.swing.swingutilities.Invokelater (new runnable () {
Public void run () {
CreateandShowgui ();
}
});
}
}
The first function and MSHTML are a bit similar. We can use setFont () to change the font and use setColor () to change the color. However, we can also make the same settings via HTML tags. (The old version is not supported).
Add icon:
ImageICON Converticon = CreateImageicon ("Images / Convert.gif", "Convert Temperature");
...
CONVERTTEMP = New JButton (icon);
Set the default button:
// set the Button to Be default button.converterframe.getrootpane (). Setdefaultbutton (ConvertTemp);
Create a formatted text domain:
// Create the format for the text field and the formatted text field
Tempcelsius = New JFORMATTEDTEXTFIELD (
New java.text.decimalformat ("## 0.0 #"));
The first seems to be a little bit, can you join JScript? I will try it.
