I have a JLabel with an ImageIcon, which I put by using the setIcon() function in JLabel. The ImageIcon then comes up, sitting to the left of the text of my JLabel. Is it possible to have the ImageIcon be on the right of the text?
Let's say the label is called "label" - Then use:
label.setHorizontalTextPosition(JLabel.LEFT);
That should work.

I am programmatically creating a text view and trying to place another textView right next to the first one. But I am unable to do it.
Here is the code I have written,
//1st textview
TextView itemText = new TextView(context);
itemText.setText(mItemText);
Typeface itemFont = Typeface.createFromAsset(context.getAssets(), "fonts/" + "Roboto" + ".ttf");
itemText.setTypeface(itemFont,Typeface.BOLD);
itemText.setPadding(0, padding, 0, 0);
itemText.setId(10);
RelativeLayout.LayoutParams itemTextParams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT,
RelativeLayout.LayoutParams.MATCH_PARENT);
itemTextParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
itemTextParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
itemText.setTextSize(font_size);
itemText.setLayoutParams(itemTextParams);
//2nd text view
TextView seperator = new TextView(context);
seperator.setText(mSeperator);
seperator.setPadding(0,padding,0,0);
seperator.setTypeface(null,Typeface.BOLD);
RelativeLayout.LayoutParams seperatorParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
seperatorParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
seperatorParams.addRule(RelativeLayout.RIGHT_OF,itemText.getId());
seperatorParams.addRule(RelativeLayout.CENTER_VERTICAL);
seperator.setLayoutParams(seperatorParams);
seperatorParams.addRule(RelativeLayout.CENTER_HORIZONTAL) works, but when I use seperatorParams.addRule(RelativeLayout.RIGHT_OF,itemText.getId()) , the text is not shown.
Can anyone point out where I am going wrong? Or is there any other way to do this?
The width of itemTextParams is set to MATCH_PARENT, so there's no space to put anything to the right of it. Change it to WRAP_CONTENT or define a width value.
First of all, I'm a long time Java/Swing developer. I recently installed JavaFX 2.2 to play around with.
I'm creating a fairly simple app, whose main window has a toolbar on top and content in the rest of the window. The obvious way to accomplish this is to use a BorderPane, and stick a ToolBar into the top section. So far, so good. However, I would like some of the controls in the toolbar to be at the left edge of the window, and some at the right edge. I can find no way to do this. I can put an invisible spacer object into the toolbar, but I only know how to give it a fixed width; it doesn't resize when the window is resized.
So I thought that instead of using a ToolBar object, I'll just use an HBox; it should be equivalent to a horizontally-oriented Swing Box object, right? And the Swing Box class has a createHorizontalGlue() method that inserts an auto-sizing spacer. Well, I can't find an equivalent in the JavaFX HBox class. Is there no simple way to do this?
I figured out how to do it using an HBox instead of a ToolBar to hold the controls; the key is the HBox.setHgrow() method, which allows you to set a spacer object to grow to fill the available space. I still don't know if it's possible to do this with an actual ToolBar instance.
/**
* Creates and populates the Node that serves as the window toolbar.
*
* #return a newly constructed and populated toolbar component
*/
private Node makeToolbar() {
// Auto-sizing spacer
Region spacer = new Region();
HBox.setHgrow(spacer, Priority.ALWAYS);
// Horizontal box containing toolbar controls
HBox box = new HBox();
box.setPadding(new Insets(8));
box.setAlignment(Pos.CENTER);
box.getChildren().addAll(openButton, spacer, resizeSlider);
// Colored background panel with drop shadow
Pane bgRect = new Pane();
bgRect.setStyle("-fx-background-color: #e0e0e0;");
bgRect.setEffect(DropShadowBuilder.create().width(1).build());
// StackPane to hold box and rectangle
StackPane stack = new StackPane();
stack.getChildren().addAll(bgRect, box);
return stack;
}
i do it this way:
private Node makeFooter(Node left, Node right) {
ToolBar footer = new ToolBar();
Region spacer = new Region();
HBox.setHgrow(spacer, Priority.ALWAYS);
spacer.setMinWidth(Region.USE_PREF_SIZE);
footer.getItems().addAll(left, spacer, right);
return footer;
}
hope i could help someone
I want to align the text in a TextArea to the right. I tried the following code:
Form form = new Form();
TextArea textArea = new TextArea("Some Arabic text ...");
textArea.setRTL(true);
textArea.setAlignment(RIGHT);
form.addComponent(textArea);
The result was just moving the scroll to left,
But the text is still not aligned RIGHT,
check the image below:
So how to align the content to the RIGHT ?
It may sound crazy for the first instance :) but setting the alignment to TextArea.LEFT solved the issue and now it's RIGHT aligned !
Form form = new Form();
TextArea textArea = new TextArea("Some Arabic text ...");
textArea.setRTL(true);
textArea.setAlignment(TextArea.LEFT);
form.addComponent(textArea);
Setting it to LEFT makes the displayed text RIGHT aligned !
Or by removing the textArea.setRTL(true) which is mirroring the display
Form form = new Form();
TextArea textArea = new TextArea("Some Arabic text ...");
textArea.setAlignment(TextArea.RIGHT);
form.addComponent(textArea);
For those who are interested in more complicated details when it's set to RTL:
the paint method of TextArea class is
public void paint(Graphics g) {
UIManager.getInstance().getLookAndFeel().drawTextArea(g, this);
}
And drawTextArea method in DefaultLookAndFeel is as follows:
int align = ta.getAbsoluteAlignment();
// remaining code is here in initial source
switch(align) {
case Component.RIGHT:
x = ta.getX() + ta.getWidth() - rightPadding - f.stringWidth(displayText);
break;
// remaining code is here in initial source
}
g.drawString(displayText, x, y);
Unfortunately TextArea.RIGHT value is 3
But when calling ta.getAbsoluteAlignment() it returns 1 (despite that the object's alignment is set by code to TextArea.RIGHT !!)
Meanwhile TextArea.Left value is 1
That's why it matched the value in the switch and was aligned to RIGHT
BTW, if you set
textArea.setAlignment(Component.RIGHT);
it will also be wrong, because Component.RIGHT outside the paint method has the value 3 not 1 !
You only have to write 'TextArea.RIGHT' instead of 'RIGHT'
textArea.setAlignment(TextArea.RIGHT);
You can use the following line:
TextArea textArea = new TextArea("Some Arabic text ...");
textArea.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);
how to put 4 button in row, as in the picture:
The distance between the elements should be changed at different resolutions
There are allot of ways to do everything in LWUIT. Its unclear from your image what your exact constraints are, I'm guessing you want the left most button to be left aligned and the right most to be right aligned. You probably also want the two other buttons to be centered.
I would implement this using a GridLayout with nested FlowLayout elements. As such:
Container c = new Container(new GridLayout(1, 4));
addButton(c, new Button("b1"), Component.LEFT);
addButton(c, new Button("b2"), Component.CENTER);
addButton(c, new Button("b3"), Component.CENTER);
addButton(c, new Button("b4"), Component.RIGHT);
private void addButton(Container c, Button b, int align) {
Container flow = new Container(new FlowLayout(align));
flow.addComponent(b);
c.addComponent(flow);
}
Play with setMargin(Component.RIGHT,x) for the first three Buttons. Set the value of x such that the Buttons are equi-partitioned in the row : you must take into account the preferredWidth of the Buttons for that. For the first Button set its margin-left to 0 ( setMargin(Component.LEFT,0) ) , and for the last Button set its right-margin to 0 ( setMargin(Component.RIGHT,0) ).
You should use use BorderLayout and add the container (described in this answer inside south)
From top to bottom I have UIView, UIScrollView, a UIImage, a UILabel, a UITextView and a UIButton.
My reason behind the top-most UIScrollView was so the whole vertical content would scroll.
What I really need a substitute for is the UITextView (5th down) because the UITextView is a subclass of UIScrollView. And this substitute must accomodate the very tall column of formatted text.
What I don't want is a scrollable object in the middle of the page; I want the whole page to be scrollable.
One more thing ... please note there's a button immediately below this tall column of text.

THANK YOU! Ashack and Pentagp. I guess I finally had to surrender and dump the idea that IB could be used for all GUI ...
The entire UIView contains a UILabel, a UIImage, a UITextView and
a UIButton at the very bottom.
The goal here was to make this entire content scrollable.
Thanks to you guys at stackoverflow.com:
using IB, un-check "Scrolling Enabled" for the UITextView
because it's a concrete type of UIScrollView
using IB, drag a UIScrollView to the UIView and match sizes and
insure that the UIScrollView encloses all sub-views
make the UITextView height = its contentSize.height
move the UIButton to below this UITextView
and then, thanks to iphonedevsdk.com:
adjust the contentSize.height of the top-most UIScrollview to
include the height of the re-positioned UIButton
Problem solved!!!
Your question is not very specific, but I think you're asking how to make a text view that does not scroll, and expands to fit the text. You can do this with UILabel, but it's a multi-step process. The same will work for UITextView if you disable scrolling and set the contentSize to match the frame dimensions.
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(100,100,100,100)];
label.font = [UIFont systemFontOfSize:24];
NSString *yourTextString = #"your text";
CGSize maximumLabelSize = CGSizeMake(100, 500);
CGSize expectedLabelSize = [yourTextString sizeWithFont:label.font
constrainedToSize:maximumLabelSize
lineBreakMode:yourLabel.lineBreakMode];
CGRect labelFrame = label.frame;
labelFrame.size.width = expectedLabelSize.width;
labelFrame.size.height = expectedLabelSize.height;
label.frame = labelFrame;
Then from there, use the label's frame to set the position of the button and all elements below it.
If I understand your problem, you don't want nested scroll.
So set yourTextView.scrollEnabled = NO; //Do it programmatically our in the nib
Also in order to display all the text set yourTextView frame height to its content height:
yourTextView.frame = CGRectMake(yourTextView.frame.origin.x,
yourTextView.frame.origin.y,
yourTextView.frame.size.width,
yourTextView.contentSize.height + (yourTextView.contentSize.width > yourTextView.frame.size.width ? (yourTextView.contentSize.width * yourTextView.contentSize.height / (yourTextView.contentSize.width - yourTextView.frame.size.width)) - yourTextView.contentSize.height :0)));
/*
If textView is dynamically filled, you have to check if yourTextView.contentSize.width is bigger than yourTextView.frame.size.width then add proportionally what is remaining to the height.
*/
At the end change your button position if needed:
yourbutton.frame = CGRectMake(yourbutton.frame.origin.x,
yourTextView.frame.origin.y + yourTextView.frame.size.height + 20, //If you want your button to be 20 point after your textView
yourbutton.frame.size.width,
yourbutton.frame.size.height);
Hope that will help you...
