I have a TextField form inside a window. Created with UiBinding. Next to the TextField is a button. I wanted to know if it was possible to create a new TextField widget when that button was pressed using UiBinder?
This is what I have:
Window class:
#UiField
TextField text;
#UiField
HorizontalPanel hPanel;
....
#UiHandler("addText")
public void onClick(SelectEvent event){
hPanel.add(text);
}
My UiBinder file:
<gxt:Window ...(generic setup)...>
<g:VerticalPanel>
<gxt:FramedPanel>
<container:VericalLayoutContainer>
<container:child>
<g:HorizontalPanel ui:field="hPanel">
<form:FieldLabel text="Text">
<form:Widget>
<form:TextField ui:field="text"/>
</form:Widget>
</form:FieldLabel>
<button:TextButton ui:field="addText"/>
</g:HorizontalPanel>
</container:child>
</container:VericalLayoutContainer>
</gxt:FramedPanel>
</g:VerticalPanel>
</gxt:Window>
When I click the button it all it does is move the button from the right side of the text field to the left. I have more textfields in the window so I played around to see what it was really doing. It's taking that field and just moving it next to the button.
Is there a way I can create a new TextField underneath the original?
Probably LazyDomElement will help you.

I am using codename one to create an application, and i am in front of a situation that is making me use the "tree component" in the pop-up of the OverFlowMenu
how can i do that?
That won't work. The overflow menu uses a renderer approach and isn't very customizable.
Instead add a command to the right side of the toolbar and show a popup dialog pointing at that button e.g.:
popupCommand = toolbar.addMaterialCommandToRightBar("", FontImage.MATERIAL_MORE_VERT, e -> showPopup());
private void showPopup() {
Button b = toolbar.findCommandComponent(popupCommand);
Dialog popup = new Dialog(new BorderLayout());
popup.add(BorderLayout.CENTER, new Tree());
popup.showPopup(b);
}
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.
Here's the deal, im trying to create a popup window that uses a dynamic text,
when the text is too large i would like to cap the height of the window and
use a scrollbar instead to navigate through it but it does not seems to be
working.
code:
final Dialog dialog = new Dialog();
dialog.setMessage(direttivaDescription);
dialog.setOverflow(Overflow.AUTO);
dialog.setWidth(600);
dialog.setHeight(50);
dialog.setIcon(someIcon);
dialog.setButtons(new Button("OK"));
dialog.addButtonClickHandler(new ButtonClickHandler() {
public void onButtonClick(ButtonClickEvent event) {
dialog.hide();
}
});
dialog.draw();
If the text is too large the window height will be resized accordingly. The funny
part is that setWidth method seems to be working just fine.
You need a container such as HLayout, VLayout, DynamicForm etc. where you can add the message in it then finally add the container in the Dialog.
Sample code:
VLayout vLayout=new VLayout();
vLayout.addMember(new Label(message));
vLayout.setOverflow(Overflow.AUTO);
vLayout.setWidth100();
...
dialog.addItem(vLayout);
dialog.draw();
snapshot:
I have used two scroll bars for controlling brightness and contrast on image after the use i want to reset the scroll bars to their initial value with a button click
I am not getting any links for that to reset scroll bars on button clicks in JavaFX?
The question somewhat unclear. Need explanation of "not getting any links". Some sample code would be helpful. Based on an assumption, try this:
final ScrollBar scrollBar = new ScrollBar();
Button btn = new Button("Reset");
btn.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
scrollBar.setValue(scrollBar.getMin());
// Or if you have stored initial value somewhere use it
scrollBar.setValue(myInitialValue);
}
});
I have a TextField in a Form. This TextField should have focus by default,
which works fine. Now I'd like the user to be aware of that and show him,
that he's inside the TextField - so the TextField cursor should be shown
and blink.
I only found drawTextFieldCursor in DefaultLookAndFeel. but I have
absolutely no idea how to apply this to my TextField.
Any help - and code would be appreciated!
Here's a sample. I still don't have it working.
public void search2() {
searchForm = new Form();
TextField searchArea = new TextField();
searchForm.setLayout(new BoxLayout(BoxLayout.Y_AXIS));
searchForm.addComponent(searchArea);
searchArea.requestFocus();
int i = Display.getInstance().getKeyCode(Display.GAME_FIRE);
searchArea.keyPressed(i);
searchArea.keyReleased(i);
searchForm.show();
}
What happens is: the TextField is focused, it can be directly edited, the "Abc" mode is shown, but what I really want is to show the user the cursor, so he KNOWS he's inside the TextField. This is not happening... if someone could show me some working code for that...
You want the text field to be in editing mode not for the text field cursor to show (which happens when editing). Use requestFocus() to make sure the text field has focus then use something like:
int i = Display.getInstance().getKeyCode(Display.GAME_FIRE);
tf.keyPressed(i);
tf.keyReleased(i);
The drawTextFieldCursor method has a Graphics parameter , so the way you can draw your cursor is :
derive TextField
in its public void paint(Graphics g) you call drawTextFieldCursor after setting the drawing methods of the TextField's paint Graphic.
