Below code only showing the textfield, but I want to include textfield and textarea. Need Help
form1 = new Form("Mobile");
tb2 = new TextField("To: ", "", 30, TextField.ANY);
TextBox tb3 = new TextBox("Message: ", "", 256, TextField.ANY);
form1.append(tb2);
// form1.append(tb3);
form1.addCommand(submitCommand);
display.setCurrent(tb3);
display.setCurrent(form1);
What you call textarea is an lcdui object TextBox; it can not be shown at the same screen as TextField.
If you're interested, refer to 'lcdui' tag info for more details on why is that (there are links to API reference, tutorials, popular libraries etc).
For the code snippet you posted, first thing that comes to mind would be to just replace TextBox to TextField, like
// ...initialization of Form and tb2
TextField tb3 = new TextField("Message: ", "", 256, TextField.ANY);
// above, TextBox has been replaced with TextField
form1.append(tb3); // show "Message" textfield above "Mobile"
form1.append(tb2);
form1.addCommand(submitCommand);
display.setCurrent(form1);
There is no such thing as TextArea in J2ME. You can show either Form with TextField[s] or TextBox, because TextBox is a Displayable. You can show only one Displayable at a time.

I try to make a label to display "You Win" and add it to winStage, but I cannot manage to display the label correctly on winStage. Some words don't show on the screen, and if I downscale further than 0.044f, the String disappears. when I add font.setUseIntegerPositions(false) to my code, the font shows correct, but the wrong label also shows. Is there a way to get this work? (hide the wrong label or get the label shows correctly), code uses Kotlin, but very similar to java
YUW N is the wrong label I want to remove, the correct "You Win" only shows when I add font.setUseIntegerPositions(false)
here's the relevant code part
private val winViewport = StretchViewport(mainStage.width, mainStage.height)
val winStage = Stage(winViewport, winBatch)
var font = BitmapFont()
var labelStyle = Label.LabelStyle()
labelStyle.font = font
labelStyle.fontColor = Color.RED
var label2 = Label("YOU WIN", labelStyle)
label2.setBounds(0f, winStage.height*2/3, winStage.width*1, winStage.height/6)
label2.setFontScale(0.07F) // 0.07f
font.setUseIntegerPositions(false)
label2.setWrap(false)
winStage.addActor(label2)
winStage.act(delta)
winStage.draw()
I have a JPanel containing a JButton Like The Following Photo:
The problem is that if I typed a text like "Test Name" it is OK because the size of the button is fit!
But if I typed a text like "Test Name Example" or any other big text I need it to do like the following if it is possible!
Note: Code for the button
JButton btnfast = new JButton();
btnfast.setSize(120, 120);
btnfast.setMinimumSize(btnfast.getSize());
btnfast.setBackground(Color.white);
btnfast.setForeground(Color.black);
btnfast.setFont(Classes.Setting.fontDef);
btnfast.setText("Test Name Example");
btnfast.setAlignmentX(Component.CENTER_ALIGNMENT);
pd2.FastAddPanal.add(btnfast);
As it says on the tin.. I cannot get a label's text to wrap. Essentially I am building like a comments panel, user enters a comment and its displayed with timestamp etc.
I want the labels to both display with ContentMode.PREFORMATTED but also wrap.
The layouts of which contain the label are fixed width (100%) as is the label obviously by default, from what I have readin the book of vaadin what I am doing should work?
here is my code snippet:
VerticalLayout container = new VerticalLayout();
rootLayout.addComponent(container);
VerticalLayout comment = new VerticalLayout();
container.addComponent(comment);
Label createdByLbl = new Label(entity.getManagedMetadata().getAttrValue("createdBy") + " said:");
createdByLbl.setId("conversation.comment.username." + repositoryUID);
createdByLbl.setStyleName("conversation-comment-username");
Label createdDateLbl = new Label(entity.getManagedMetadata().getAttrValue("createdDate"));
createdDateLbl.setId("conversation.comment.createddate." + repositoryUID);
createdDateLbl.setSizeUndefined();
String text = entity.getDataNode().getAttrValue("text");
Label textLbl = new Label(text, ContentMode.PREFORMATTED);
textLbl.setId("conversation.comment.text." + repositoryUID);
comment.addComponent(createdByLbl);
comment.addComponent(textLbl);
comment.addComponent(createdDateLbl);
comment.setExpandRatio(createdByLbl, 0.2f);
comment.setExpandRatio(textLbl, 0.7f);
comment.setExpandRatio(createdDateLbl, 0.1f);
Note the container is also wrapped by CssLayout (rootLayout), which is full sized.
I want the textLbl as seen above to display as formatted should the user enter text on separate lines themselves and wrap if they have entered a long paragraph comment.
Here is a picturing showing my dilemma.
Any help would be appreciated.
Thanks,
Try with css.
For example:
textLbl.addStyleName("wrapLine");
Css:
.wrapLine{
word-wrap: break-word; /* IE */
white-space: -moz-pre-wrap; /* Firefox */
}
I am trying to learn Wicket. One of the problems I encounter, is changing the values of components like a label.
This is how I declare the label:
Label message = new Label("message", new Model<String>(""));
message .setOutputMarkupId(true);
add(message );
The only solution I can find:
Label newMessage= new Label(message.getId(), "MESSAGE");
newMessage.setOutputMarkupId(true);
message.replaceWith(newMessage);
target.add(newMessage);
Is there a better/easier way to edit the value of a Wicket label and display this new value to the user?
Thanks!
I think you did not understand what Models are. Your example could be rewritten as follows
Model<String> strMdl = Model.of("My old message");
Label msg = new Label("label", strMdl);
msg.setOutputMarkupId(true);
add(msg);
In your ajax event
strMdl.setObject("My new message");
target.add(msg);
All I want to do is have a JOptionPane inputDialog with a JTextArea instead of a JTextField.
I tried putting the JTextArea inside of the Message parameter like so
Object[] inputText = new Object[]{new JLabel("Enter Graph Information"),
newJTextArea("",20,10)};
graphInfo=(String)JOptionPane.showInputDialog(null,
inputText,
"Create Graph",
JOptionPane.PLAIN_MESSAGE,
null,
null,
"");
But it still has the text field at the bottom and I cannot get the text from the JTextArea.
Is there any way to either remove the original text field and get the text from the jtextarea or replace the text field with the text area completely? I'm trying to avoid having to make a custom dialog if possible and this "seems" like something that should be easy to do?
You're on the right lines; you just need to use showConfirmDialog instead of showMessageDialog, which allows you to pass any Component as your "message" and have it displayed within the JDialog. You can then capture the contents of the JTextArea if the user clicks OK; e.g.
int okCxl = JOptionPane.showConfirmDialog(SwingUtilities.getWindowAncestor(this),
textArea,
"Enter Data",
JOptionPane.OK_CANCEL_OPTION)
if (okCxl == JOptionPane.OK_OPTION) {
String text = textArea.getText();
// Process text.
}
If you want to show a JLabel in conjunction with your JTextArea you can create and pass in a JPanel containing both Components; e.g.
JTextArea textArea = ...
JPanel pnl = new JPanel(new BorderLayout());
pnl.add(new JLabel("Please enter some data:"), BorderLayout.NORTH);
pnl.add(textArea, BorderLayout.CENTER);
JOptionPane.show...
