Create code:

 
Private void addToggleButton (JToolBar JToolBar, Element tool) {
JToggleButton togBtn=new JToggleButton (); 
TogBtn. Elegantly-named setName (tool. AttributeValue (Widgets. Key_tool_attr_name)); 
TogBtn. SetText (tool. AttributeValue (Widgets. Key_tool_attr_text)); 
TogBtn. SetActionCommand (tool. AttributeValue (Widgets. Key_tool_attr_cmd)); 
//togBtn. SetIcon (new ImageIcon (tool. AttributeValue (Widgets. Key_tool_attr_icon))); 
Int w=Integer. ParseInt (tool. AttributeValue (Widgets. Key_tool_attr_width)); 
Int h=Integer. ParseInt (tool. AttributeValue (Widgets. Key_tool_attr_height)); 
Dimension size=new Dimension (w, h); 
TogBtn. SetSize (size); 
TogBtn. SetPreferredSize (size); 
TogBtn. SetBackground (RdrmColor. ParseToColor (tool. AttributeValue (Widgets. Key_tool_attr_bcolor))); 
TogBtn. SetForeground (RdrmColor. ParseToColor (tool. AttributeValue (Widgets. Key_tool_attr_fcolor))); 
Boolean enabled=!" False ". The equals (tool. AttributeValue (Widgets. Key_tool_attr_enabled))? True, false; 
TogBtn. SetEnabled (enabled); 
TogBtn. SetBorder (null); 
//what kind listener JToggleButton 
TogBtn. AddChangeListener (changelistener); 
Jtoolbar. Add (togBtn); 
} 

Listener code:

 
Public void createActionListener () {
Applistener=new ActionListener () {
@ Override 
Public void actionPerformed (an ActionEvent e) {
RequestExecute (e); 
} 
}; 

Changelistener=new changelistener () {
@ Override 
Public void stateChanged (ChangeEvent e) {
JToggleButton toggleBtn=(JToggleButton) um participant etSource (); 
System. The out. Println (toggleBtn. GetText () + "if selected:" + toggleBtn. An isSelected ()); 
//setMute (JTB. An isSelected ()); 
//System. Out. Println (isMute); 
} 
}; 
ItemListener=new itemListener () {
@ Override 
Public void itemStateChanged (ItemEvent e) {
If (um participant etStateChange ()==ItemEvent. SELECTED) {
//when JRadioButton is selected, change the value of the variable engine_selected 
JRadioButton rBtn=(JRadioButton) um participant etSource (); 
Engine_selected=rBtn. GetName (). The trim (); 
The switch (engine_selected) {
Case engine_selected_checktext: 
System. The out. Println (((JRadioButton) um participant etSource ()). The getActionCommand ()); 
break; 
Case engine_selected_offline: 
System. The out. Println (((JRadioButton) um participant etSource ()). The getActionCommand ()); 
break; 
Case engine_selected_online: 
System. The out. Println (((JRadioButton) um participant etSource ()). The getActionCommand ()); 
break; 
Case engine_selected_websocket: 
System. The out. Println (((JRadioButton) um participant etSource ()). The getActionCommand ()); 
break; 
} 
} 
} 
}; 
} 

After execution, in the mouse, click, triggered when they leave 7 times:


I just want to in the state of the mouse is triggered when a, how to do?

CodePudding user response:

Actually, want to trigger an event when JTogelButton to select/deselect,
In most cases use ActionListener is enough, and whether the mouse to click or press the space change state of the button, will trigger
Only a handful of cases, such as: "where else would you call directly by code setSelected (true/false) change button state,
Only in that case button state changes, not trigger ActionListener
If you have such a demand, can use ItemListener rather than ChangeListeter
ChangeListeter is not really a very friendly event listeners, seldom go to with it

 
BTN. AddItemListener (new ItemListener () {
@ Override 
Public void itemStateChanged (ItemEvent e) {
Int stateChange=um participant etStateChange (); 
If (stateChange==ItemEvent. SELECTED) {//SELECTED 
System. The out. Println (true); 
} else if (stateChange==ItemEvent. DESELECTED) {//uncheck 
System. The out. Println (false); 
} 
} 
});

I also feel this is a problem of listeners, who has examined the source code, there is only one method, there is little that can judge through ChangeEvent e
