In my code, on one class, I'm trying to check if the button has been pressed on my other frame (class). If this is true, then some code will be carried out. However, I cannot find any code whatsoever to check if the button has been pressed or not.
Here is my code:
editBanana bFrame = new editBanana();
String getLocation = bFrame.editLocationField.getText();
javax.swing.JButton saveButt = bFrame.saveEditButton;
...
...
//If button is pressed from my other form, then do this code
if (saveButt.getModel().isPressed())
{
System.out.println("Saved");
}
When I run this code, and press the button, this code does not work and nothing happens.
I'm thinking because this isn't working, that it runs through this code first, and then I press the button. So for the code where I click my button, I simply call the main class again so that it iterates through the code with the button now pressed. But it still does not execute my code.
Which code should I be using in order to find whether or not my button has been pressed?
Thanks.

I am trying to create a button form component that tests the connection without using the next button because it isn't required before continuing to the next screen. However all the variables that are set in the ui dialog are unavailable till I hit the next button. Anyone have experience of how to either access those variables or force them to be available while on the same dialog without pressing next button.
Variable name: smtp.host
When I read the variable by pressing a button it is empty until I click next -> then back and then I click the button it is assigned and it functions properly.
Run this before you use any of the variables and it will work perfectly.
//Save the variables from the form before continuing
if(!formEnvironment.saveFormComponents())
{
Util.logError(context, "Unable to save form components");
}
I created a main class and an adapter for my ListView. In this adapter I created three different types of rows. One of them is a row with EditText. In the adapter class I created a Listener for "Enter" click. After an user clicks "Enter" button, the information entered in EditText saves in a variable.
What I need: I want my app (my main class) wait until this variable changes (from null to something) and after continue doing some actions.
I tried to create a loop, but if ended up with error.
Try to use onEditorDoneListener on the edittext(example is here) when the user presses done button on the keyboard, you can verify the value of the editText and proceed accordingly.
After an user clicks "Enter" button, the information entered in EditText saves in a variable.
It seems that this variable (presumably a String) is only ever changed when the "Enter" button is pressed. So whatever action you want when that String is changed, put them into the onClick method in your Java:
private void enterButtonOnClick(View v) {
// Store the text from EditText into the String variable here
// ...
// Your string variable just changed, so do the desired action...
// Stuff
// and
// things
}
And then in your XML, add this in the button attribute :
android:onClick="enterButtonOnClick"
I have a button and a textview with the number 1 displayed when my app is running. When i press and hold the button i want the value to continuosly increment till I let go of the button. It is very frustrating for me because i used to know how to do this and it was as simple as setting the button properties to something in xml. However I have forgotten how and i have searched through the internet and the examples i have found implement an ontouch listener that only increments the value by one. But i want the value to be increment continuosly depending on how long the user presses the button. this is not a repeat of

as they did not work for me. so can some remind me how to get a button to increment a value continuosly when you press and hold the button?
Use onTouchListener and start/stop your counter routine on MotionEvent.ACTION_DOWN and MotionEvent.ACTION_UP

bramburys answer in the link above worked perfectly whilst other answers incremented one at a time when the button was pressed whilst bramburys incremented continuously.
i'm creating a statebased game using slick 2d, and lwjgl. I currently am using if statements to check whether the mouse is inside the area of the button, and another if statement to check whether the mouse button is down (the button is just a picture g.drawImage("buttonImage.png", x,y); ). So I have a button where it changes states to the main menu from the play state, but because the mouse button is down it clicks a button on the main menu state before the user is able to release the button. So I need to check if they released the button before the if statement on the main menu is triggered.
What you need is a boolean flag that is triggered when the Mouse is down, like this:
(psuedo code)
if(Mouse.isButtonDown()) {
downFlag = true;
}
Then after that:
if(!Mouse.isButtonDown() && downFlag)) {
changeState();
}
Please let me know if this helped :)
