Experience in creating single-host tetris games (4)

The following describes how to build the game tool interface. Define the following attributes in mainframe

Private gamepanel;
// Level
Private jlabel leveltextlabel = new jlabel ("level ");
Private jlabel levellabel = new jlabel ();
Private box leveltextbox = Box. createhorizontalbox ();
Private box levelbox = Box. createhorizontalbox ();
// Score
Private box scoretextbox = Box. createhorizontalbox ();
Private box scorebox = Box. createhorizontalbox ();
Private jlabel scoretextlabel = new jlabel ("score ");
Private jlabel scorelabel = new jlabel ();
// Next
Private box nexttextbox = Box. createhorizontalbox ();
Private jlabel nexttextlabel = new jlabel ("Next ");
// Continue
Private box resumebox = Box. createhorizontalbox ();
Private jlabel resumelabel = new jlabel ();
// Pause
Private box pausebox = Box. createhorizontalbox ();
Private jlabel pauselabel = new jlabel ();
// Start
Private box startbox = Box. createhorizontalbox ();
Private jlabel startlabel = new jlabel ();
// Tool
Private jpanel toolpanel = new jpanel ();
Add the following code to the constructor in the mainframe class to create the public mainframe (){
This. currentlevel = 1;

This. gamepanel = new gamepanel (this );

Boxlayout toolpanellayout = new boxlayout (this. toolpanel, boxlayout. y_axis );
This. toolpanel. setlayout (toolpanellayout );
This. toolpanel. setborder (New etchedborder ());
This. toolpanel. setbackground (color. Gray );
// Score
This. scoretextbox. Add (this. scoretextlabel );
This. scorelabel. settext (string. valueof (this. Score ));
This. scorebox. Add (this. scorelabel );
// Level
This. leveltextbox. Add (this. leveltextlabel );
This. levellabel. settext (string. valueof (this. currentlevel ));
This. levelbox. Add (this. levellabel );
// Continue
This. resumelabel. seticon (resume_icon );
This. resumelabel. setpreferredsize (new dimension (3, 25 ));
This. resumebox. Add (this. resumelabel );
// Pause button
This. pauselabel. seticon (pause_icon );
This. pauselabel. setpreferredsize (new dimension (3, 25 ));
This. pausebox. Add (this. pauselabel );
// Start
This. startlabel. seticon (start_icon );
This. startlabel. setpreferredsize (new dimension (3, 25 ));
This. startbox. Add (this. startlabel );
// Next
This. nexttextbox. Add (this. nexttextlabel );

This. toolpanel. Add (box. createverticalstrut (10 ));
This. toolpanel. Add (scoretextbox );

This. toolpanel. Add (box. createverticalstrut (30 ));
This. toolpanel. Add (this. nexttextbox );

This. blankbox. Add (box. createhorizontalstrut (99 ));
This. toolpanel. Add (blankbox );

This. Add (this. gamepanel, borderlayout. center );
This. Add (this. toolpanel, borderlayout. East );
