I want to create checkbox with text in the left side and the checkbox component on the right side. How I can switch their place?
CheckBox cb = new CheckBox("Show on Startup");
In JavaFX 8, you can do it like this:
Label lb = new Label("left check");
lb.setGraphic(new CheckBox());
lb.setContentDisplay(ContentDisplay.RIGHT); //You can choose RIGHT,LEFT,TOP,BOTTOM
There might be an easier way, but you can use a label and wrap it with the CheckBox in a HBox:
HBox box = new HBox();
CheckBox cb = new CheckBox();
Label text = new Label("Show on Startup");
box.getChildren().addAll(text, cb);
box.setSpacing(5);
It would be nice if the CheckBox considered the box as its "content" like some of the other controls based on Labeled. Then the contentDisplayProperty could be set to ContentDisplay.RIGHT to achieve this. A nice side-effect would be that we could change the rendering of the box with a setGraphic() call.
As of my release (1.8 EA b129), CheckBox doesn't work that way.

I would like to have a customized Dialog styling, having another background color and a rounded border, as it looks nicer than the gray rectangle that comes by default.
This is partially possible, by styling the Contentpane of the Dialog. The problem is, that the underlying Dialog Style is still there, in which the contentpane is shown. And it seems the Dialog UDID itself cannot be changed, nor can the "Dialog" style be overwritten in the designer nor by code.
Form hi = new Form();
hi.getUnselectedStyle().setBgColor(0xffffff);
Button but = new Button("open dialog");
but.addActionListener(e -> {
Dialog d = new Dialog(BoxLayout.y());
d.setUIID("Container"); // this line has no effect, the outside dialog component is still visible
Style s = d.getContentPane().getUnselectedStyle();
s.setBorder(RoundRectBorder.create());
s.setBgColor(0x00ff00);
s.setBgTransparency(255);
s.setMargin(5, 5, 5, 5); // adding some margin between contentpane and Dailog container, to be more obvious
d.setDisposeWhenPointerOutOfBounds(true);
// title
Label title = new Label();
title.setText("Confirmation");
d.add(title);
// body field with spanlabel info text
SpanLabel bodyLabel = new SpanLabel("Body Text");
d.add(bodyLabel);
// delete button
Button okButton = new Button("Ok");
okButton.addActionListener(e2 -> {
d.dispose();
});
// exit button
Button exitButton = new Button("Cancel");
exitButton.addActionListener(e3 -> {
d.dispose();
});
d.add(GridLayout.encloseIn(2, okButton, exitButton));
d.show();
});
hi.add(but);
hi.show();
In above image, the outermost dark gray is the tinted area outside the dialog. The green is the content pane with the intended rounded border. the light grey in between comes from the Dialog style that I would like to get rid off.
Can this be done?
Short answer: setDialogUIID("Container");
However dialogs are a bit problematic to customize via code, I would strongly recommend styling them via the designer/css as we just didn't design them for hand styling and so you're relying on internal implementation details that might break.
When you invoke getContentPane() on the Dialog you're styling the content pane of the Dialog. Not the Dialog itself so the dialog styling still has the non-transparent background. You can use getDialogStyle() to style the Dialog itself. I'm not sure how well that will work.
Good day all,
I have a simple Dialog started after click button, I post my code:
Dialog dialog;
super();
dialog = new Dialog("Dialog example");
dialog.addText(strFmt("Text to show"));
dialog.addText(strfmt("SecondText to show"));
dialog.run();
I will show a Dialog window loollike this :
It's possible to set the position from code the Text: Text to show ?
For example, if I want to centered position the second text how should I do?
I tried to put blanks in the code:
dialog.addText(strfmt(" Text to show"));
But nothing changes, and this I think not good method.
I saw any suggestions on Web but or I do not use well or is not suitable for me: Example-suggestions.
Exist a method to do what I want?
Thanks for help,
enjoy!
You can center the text using the form control:
Dialog dialog = new Dialog("Dialog example");
DialogText t1 = dialog.addText(strFmt("Text to show"));
DialogText t2 = dialog.addText(strfmt("SecondText to show"));
FormStaticTextControl c1 = t1.control();
c1.widthMode(FormWidth::ColumnWidth);
c1.alignment(FormAlignment::Center);
dialog.run();
The first control is now centered (to the surrounding group).
You have to give it ColumnWidth, otherwise the control would have the minimum size and the centering would have no effect.
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'm trying to make a box that allows you to select some variables, and re-order the ones that are selected. So the LEFT box starts filled, the RIGHT box starts empty. You move items from the left to the right, and on the right you can re-arrange their order (with the up and down buttons). This lets you pick what items you want and in what order (for sorting purposes in another section of the program).
The layout I'm going for looks like of like this:
Unfortunately, it's coming out like... well... :-(
The functionality I'm looking for all works. Yay. I am just having a very hard time with the layout. I think if I can reach the following four primary objectives, I'll be set.
How can I get the OK and CANCEL buttons on the bottom instead of above the multis?
How can I get the multis to have a pre-set size (let's say... 10)
How can I get the arrow buttons to be stacked vertically instead of horizontally?
How can I get the arrow buttons to be between the two multis?
I figure each of these particular objectives are probably one-liners, perhaps a little bit of plumbing here and there...
On a side note, I'm using GridLayout - this might be a poor choice. Is there a better choice for something like this?
Without further ado, here's the code that generates this horrid mess...
#Override
protected Control createDialogArea(Composite parent) {
parent.getShell().setText("Multi-sort");
Composite dialogcomp = new Composite(parent, SWT.NONE);
dialogcomp.setLayout(new GridLayout(3, false));
available = new List(getShell(), SWT.BORDER | SWT.V_SCROLL);
for(String t : MultiSortDialog.availableNames) {
available.add(t);
}
used = new List(getShell(), SWT.BORDER | SWT.V_SCROLL);
for(String t : MultiSortDialog.usedNames) {
used.add(t);
}
createButton(parent, ADD, ">", false);
createButton(parent, REM, "<", false);
createButton(parent, UP, "^", false);
createButton(parent, DOWN, "V", false);
return dialogcomp;
}
I would suggest you simple use the Dialog's default OK and Cancel buttons and not trying to lay out your own. SWT has a nice system for placing them in the system default location (i.e., on Mac OS, the OK button will be on the right, which is the correct location.)
Don't use Dialog.createButton() to create buttons. This creates a button on your dialog which, although it sounds like what you want to do, actually isn't. This creates a button in the style of OK or Cancel buttons, expected to be placed in the button bar composite that the Dialog class owns and styled appropriately for the bottom row OK/Cancel buttons. You want to create a new Button in the composite you're creating. That is:
Button addButton = new Button(dialogcomp, SWT.PUSH);
addButton.setText(">");
addButton.addSelectionListener(...);
To stack the buttons vertically, create a new composite inside dialogcomp to contain them.
To put the arrow buttons between the Lists, you need to ensure that you add things in the correct order. With a GridLayout, you need to add widgets in the order that you want them to appear.
Other points:
Don't change the title of the dialog by calling Shell.setText(). Call setText() in your
Don't try to parent your Lists inside the parent shell. You're given a composite to put things in. This will wreak havoc on your layouts. You're basically hoisting widgets up into things you don't own and don't layout. Instead, put it in the Composite you created.
You may also wish to create buttons with the type SWT.ARROW | SWT.LEFT instead of simply drawing a < sign. It may be more visually appealing. Just something to investigate.
A simple rearrangement of your code, creating Buttons properly, and creating a new composite to hold the buttons, will get you much closer:
Composite dialogcomp = new Composite(parent, SWT.NONE);
dialogcomp.setLayout(new GridLayout(3, false));
available = new List(dialogcomp, SWT.BORDER | SWT.V_SCROLL);
for(String t : MultiSortDialog.availableNames) {
available.add(t);
}
Composite buttonComposite = new Composite(dialogcomp, SWT.NONE);
buttonComposite.setLayout(new GridLayout(1, false));
Button addButton = new Button(buttonComposite, SWT.PUSH);
addButton.setText(">");
Button removeButton = new Button(buttonComposite, SWT.PUSH);
removeButton.setText("<");
Button upButton = new Button(buttonComposite, SWT.PUSH);
upButton.setText("^");
Button downButton = new Button(buttonComposite, SWT.PUSH);
downButton.setText("v");
used = new List(dialogcomp, SWT.BORDER | SWT.V_SCROLL);
for(String t : MultiSortDialog.usedNames) {
used.add(t);
}
This will probably get you pretty close to what you want. However, you will probably want to apply GridDatas for each of your instances. For example, your two Lists will probably want to grab and fill horizontally and vertically to fill the layout as the Dialog is resized. But I'll leave that as an exercise for the reader.
I was wondering if it was possible to replace one control in a TableLayoutPanel with another at runtime. I have a combo box and a button which are dynamically added to the TableLayoutPanel at runtime, and when the user selects an item in the combo box and hits the button, I'd like to replace the combobox with a label containing the text of the selected combo box item.
Basically, if I could simply remove the control and insert another at it's index, that would work for me. However I don't see an option like "splice" or "insert" on the Controls collection of the TableLayoutPanel, and I was wondering if there was a simple way to insert a control at a specific index. Thanks in advance.
Fixed this by populating a panel with the two controls I wanted to swap and putting that into the TableLayoutPanel. Then I set their visibility according to which I wanted to see at what time.
This is what I've been able to come up with for what I needed. It gets the position of the ComboBox and makes a new label using the selected value.
// Replaces a drop down menu with a label of the same value
private void lockDropMenu(ComboBox dropControl)
{
TableLayoutPanelCellPosition pos = myTable.GetCellPosition(dropControl);
Label lblValue = new Label();
myTable.Controls.Remove(dropControl);
if (dropControl.SelectedItem != null)
{
lblValue.Text = dropControl.SelectedItem.ToString();
lblValue.Font = lblValue.Font = dropControl.Font;
// Just my preferred formatting
lblValue.AutoSize = true;
lblValue.Dock = System.Windows.Forms.DockStyle.Fill;
lblValue.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
myTable.Controls.Add(lblValue, pos.Column, pos.Row);
}
}
