I was reading through the article here about JTaskPane.
I want to add an image icon close to the expanding/collapsing icon, instead of the default icon on the left of the title ('Product' as shown in the below image).
I found that I can remove the default icon by passing null to the setIcon method.
JTaskPaneGroup ProductMenu = new JTaskPaneGroup();
ProductMenu.setTitle("Product");
ProductMenu.setIcon(null);
Any idea how I could add a new icon close to the expanding/collapsing icon as follows?

I have an SpannableString text with links on com.google.android.material.checkbox.MaterialCheckBox view.
I need to disable actual checkbox toggling while user clicks on link in CheckBox text.
I achieved that by caling view.cancelPendingInputEvents() in ClickableSpan's onClick.
However, the ripple effect on the checkbox is still present. I was able to disable it by calling this, also in ClickableSpan's onClick:
var drawable = textView.background
if (drawable is RippleDrawable) {
drawable = drawable.findDrawableByLayerId(0)
textView.background = drawable
}
The problem is, how I should revert this? How to revert default MaterialCheckBox ripple effect after click is done?
I create one activity(Home activity)inside home activity I add frame layout & some buttons. in frame layout I load fragment(Home fragment)inside home fragment I create Tab Layout now my question is when we select button(from home activity)so change regarding tab is their any possible way??
Note: I can not use viewpager because of some reason
my flow is
(1) Activity->frame layout && buttons
(2) frame layout-> load fragment(Home fragment)-> tab layout-> new frame layout which contains diff. fragment regarding tabs.
when click on activity's button so change tab
Thanks in advance
Try this :
yourTabLayout.getTabAt(tabPosition).select();
tabPosition is an int that determinants which tab will be selected
For example : 0 will select the first tab, 1 will select the second tab, 2 will select the third tab and so on
I wanted to use a image as a button. I got it working, but it is not very well made, please take a look at the screenshot. As you can see the Button itself is a lot bigger than the image, but I wanted it to be as big as the image:
The actual Button is bigger than the Image. The goal here is that there is nothing but the image to click. How can I achieve this? Here is the code ofthe button on the screenshot:
Button testButton = new Button();
String basepath = VaadinService.getCurrent().getBaseDirectory().getAbsolutePath();
testButton.setIcon(new FileResource(new File(basepath + "/VAADIN/themes/mytheme/img/Button.png")));
loginForm.addComponent(testButton);
I know that
testButton.setStyleName(BaseTheme.BUTTON_LINK)
makes the button invisible, but unfortunately that does not adjust the size of the button, just the visbility..
You can simply add a click listner to an image instead of using a button.
Image image = new Image(null, new ClassResource("/images/button-img.jpg");
image.addClickListener(e -> System.out.println("click"));
image.addStyleName("my-img-button");
And add this css, I use the #Stylesheet annotation to add in CSS.
.my-img-button {
cursor: pointer;
}
It works for me:
Button button = new Button();
button.setStyleName(ValoTheme.BUTTON_LINK);
button.setIcon(new ClassResource("/images/button-img.jpg"));
button.addClickListener(e -> System.out.println("click"));
Maybe you have additional css defined?
Maybe your button is contained in a layout with a fixed height?
Also make sure that your button has no width/height configured, so it can automatically adjust its size to that of the icon image.
The next problem you'll probably run into is the focus border:
Another approach would be to use a layout click listener, and add you own mouse-over/hover/focus styling via CSS.
VerticalLayout layout = new VerticalLayout(new Image(null, new ClassResource("/images/test.png")));
layout.addLayoutClickListener(e -> System.out.println("click"));
With Vaadin 14:
Image img = new Image("src");
Button testButton = new Button(img);
Quite straightforward.
In my JAVAFX application, i am having imageviews in a tilepane , i want to implement the multi select like functionality like in android for images . I tried adding border style to the imageView on click event but that didnt work. Is there any way to achieve this.
You can embed the Image in a JavaFX Button, and set the OnAction methods of the Button:
imageButton.setOnAction(new EventHandler<ActionEvent>() {
#Override public void handle(ActionEvent e) {
System.out.println("Changing the color of the button's border :");
imageButton.setStyle("-fx-border-color:blue;");
System.out.println("For further reference, you can save the button or the image in a TreeSet:");
treeSet.add(imageButton);
}
});
If a simple click is enough to select the image, you can define the OnAction method of the Button like above. However if you need a long click (push and hold in Android style) to change the selection status of the image, you can find more information on 'push and hold' click here : how to achieve javafx mouse event "push and hold"? .
How do you change the button text of FileDialog (not JFileChooser)? The two modes specify the button text:
FileDialog.LOAD -> "Open"
FileDialog.SAVE -> "Save"
But I want the button to say something else. Is it possible to change this text?
You cant change button text only with FileDialog methods, the only text you can edit in it is window's title which opens when you press for example "Open".
FileDialog fd = new FileDialog(FdExample.this, "select File", FileDialog.LOAD);
fd.setTitle("any new title");
If you want custom text in button, you can use JButton and ActionListener to activate FileDialog.
Probably this will be the best way.
FileDialog dialog = new FileDialog(Display.getDefault().getActiveShell(),SWT.SAVE);
