So yeah ... I got tired of trying to get wxpython and pygtk to work for me and make me those buttons, so I did something even better!!

while 1:


    for event in pygame.event.get():
        
        Button1.Update( event )    
        Button2.Update( event )
        Button3.Update( event )

        if Button1.Pressed: ExecuteButton1()
        elif Button2.Pressed: ExecuteButton2()
        elif Button3.Pressed: ExecuteButton3()

Man it executes so well! I'm happy with myself.

It's awesome because it figures out the size of the button for you and everything, and it gets highlighted when your cursor is on top. Turns brighter when you click it, and if you hold it it stays clicked until you let go or move the cursor off (but only executes the actual command when the button is clicked)!

It's not perfect at figuring out the center of where to place the font though, but it's pretty close.

And I haven't had time to clean up the code yet from when I was last messing with it to try something else.

If anyone wants to make me some button graphics it's very simple, three sets of the following: one 5 x 30, one 1 x 30, and a flip of the first 5 x 30 (as seen in the zip and ftp). For my buttons, the black around the edges is supposed to be transparent, but the best picture program I have is paint (yes I made the buttons in Paint).

EDIT: By the way, I fixed my problem with destroying the queue of keys pressed. I had the right idea with just throwing in an empty "for event in pygame.event.get()" . I was just putting it in the wrong place!! :eek:

As long as you go:

(Toggle Plain Text)

for event in pygame.event.get():"void"

after you used time.sleep. It won't queue the buttons you might have pressed while the time.sleep function was running!

Why not move:

(Toggle Plain Text)

if Button1.Pressed: ExecuteButton1()
elif Button2.Pressed: ExecuteButton2()
elif Button3.Pressed: ExecuteButton3()

Into the Update function, and in the Button constructor pass a function that will be used as a callback. Just.. cleaner design.

How would I make it so the user gets to decide what happens after the button is pressed then? And when the button can be pressed?

After the button is pressed? Well, if you have a callback:

(Toggle Plain Text)

def button1pressed():
    # code that I want to do after the button is pressed
mybutton1 = Button(...)
mybutton1.onclick = button1pressed

Then you put the code that you want to be executed in that function..?

Care to re-phrase what you mean by "when the button can be pressed"? Do you want to disable the button? If so, you should make a Button.disable and Button.enable function respectively. The Update function will call the callback as long as the mouse is down on the button and the button is not disabled.

Well I mean with mine, you can tell the program exactly where to allow the processing of the button click and etc...I don't really get yours either so yours is probably the same. But either way I think mine works fine for the uses I'll need it for.

Cerulean · Jul 6th, 2005, 3:27 PM

Sure, i'm just saying it's generally not good to have different pieces of code that do different things split apart. Saves you a headache later, but yeah.

HUZZAH!

Radio buttons!

For in my RPG where you get to select things like music/sfx volume and text scroll speed.

I'm happy with myself. For full code and graphics, download the 8 kb zip here: http://1v7.com/drsane/Button/ It's awesome because it figures out the size of the button for you and everything, and it gets highlighted when your cursor is on top. Turns brighter when you click it, and if you hold it it stays clicked until you let go or move the cursor off (but only executes the actual command when the button is clicked)! It's not perfect at figuring out the center of where to place the font though, but it's pretty close. And I haven't had time to clean up the code yet from when I was last messing with it to try something else. If anyone wants to make me some button graphics it's very simple, three sets of the following: one 5 x 30, one 1 x 30, and a flip of the first 5 x 30 (as seen in the zip and ftp). For my buttons, the black around the edges is supposed to be transparent, but the best picture program I have is paint (yes I made the buttons in Paint). EDIT: By the way, I fixed my problem with destroying the queue of keys pressed. I had the right idea with just throwing in an empty "for event in pygame.event.get()" . I was just putting it in the wrong place!! :eek: As long as you go: (Toggle Plain Text) for event in pygame.event.get():"void" for event in pygame.event.get():"void" after you used time.sleep. It won't queue the buttons you might have pressed while the time.sleep function was running! __________________ Waterloo's Canadian Computing Competition (CCC) - Stage 2 Problems, Solutions, and Test Data Last edited by Sane; Jul 5th, 2005 at 10:59 PM.

Just.. cleaner design.

But either way I think mine works fine for the uses I'll need it for. __________________ Waterloo's Canadian Computing Competition (CCC) - Stage 2 Problems, Solutions, and Test Data
