Java JLabel/JButton: on some systems I get “…” (an ellipsis) and on some systems I don't. how can I force to disable the ellipsis at all?

阅读更多关于 Java JLabel/JButton: on some systems I get “…” (an ellipsis) and on some systems I don't. how can I force to disable the ellipsis at all?

On most systems, the content in my JLabel just shows fine. It is also resided in a way that it should be always big enough to show its content text because I basically do this: label.setText(text); label.setFont(new Font(fontName, 0, 12)); int width = label.getFontMetrics(label.getFont()).stringWidth(text); int height = 21; // this should always be enough label.setBounds(new Rectangle(x, y, width, height)); But on some systems (not my own so I cannot really debug it that easy), it cuts the text and shows "..." at the end. You can see the full code here and you can see the example here

How to convert Icon from JLabel into BufferedImage?

阅读更多关于 How to convert Icon from JLabel into BufferedImage?

Simple, very straight forward but seems uncle google and me getting confused. I have single JLabel that already has its own Icon . How do I convert the Icon obtained from JLabel into a BufferedImage ? Is there any way around: I tried to multiple casting like this .. final BufferedImage bf1 = (BufferedImage)((Image)jll_img.getIcon()); ..but it failed. trashgod To amplify on @Andrew Thompson's answer , note that an object that implements the Icon interface knows how to paint something, but it may not have been asked to do so yet. In contrast, a BufferedImage has "an accessible buffer of image

Java: Linebreaks in JLabels?

阅读更多关于 Java: Linebreaks in JLabels?

I'm trying to make a Swing JLabel with multiple lines of text. It's added just fine, but the line breaks don't come through. How do I do this? Alternatively, can I just specify a maximum width for a JLabel and know that the text would wrap, like in a div? private void addLegend() { JPanel comparisonPanel = getComparisonPanel(); //this all displays on one line JLabel legend = new JLabel("MMM FFF MMM FFFO O OOM M MMMM.\nMMM FFF MMM FFFO O OOM M MMMM.\nMMM FFF MMM FFFO O OOM M MMMM.\n"); comparisonPanel.add(legend); } Use HTML in setText, e.g. myLabel.setText("<html><body>with linebreak</body>

Draw a JButton to look like a JLabel (or at least without the button edge?)

阅读更多关于 Draw a JButton to look like a JLabel (or at least without the button edge?)

问题 I've got a JButton that for various reasons I want to act like a button, but look like a JLabel. It doesn't actually have to be a JLabel under the hood, I just don't want the raised button edge to show up. Is there an easy way to turn off the "button look" for JButtons but keep all the button functionality? I could build some kind of composed subclass hyperbutton that delegated to a jlabel for display purposes, but I'm really hoping there's something along the lines of button.lookLikeAButton

Resize a picture to fit a JLabel

阅读更多关于 Resize a picture to fit a JLabel

I'm trying to make a picture fit a JLabel. I wish to reduce the picture dimensions to something more appropriate for my Swing JPanel. I tried with setPreferredSize but it doesn't work. I'm wondering if there is a simple way to do it? Should I scale the image for this purpose? Gilbert Le Blanc Outline Here are the steps to follow. Read the picture as a BufferedImage. Resize the BufferedImage to another BufferedImage that's the size of the JLabel. Create an ImageIcon from the resized BufferedImage. You do not have to set the preferred size of the JLabel. Once you've scaled the image to the size

I have a jLabel with an Icon that I want to print in a printer (canon,hp,epson anything) using a button. How can I do that? Any useful code? Code snippet? links? All I can see is like this: How to print content of a label in java? But It's not what I want. I'm using netbeans Thanks in advance. Basically, the answer will depend on whether the label is displayed on the screen or not. To ensure that the label (or in fact, any component) can be printed, it must first be sized properly... This can be done using setSize and feeding it getPreferredSize at the very basic level. The next step is
