After dragging and dropping a button in the design view, do I need to set the button to be visible in the source code? After testing it, the buttons do not appear.
befor using Drag and drop in netbeans you have to Drop Panel in form,then drop other component in the panel. for example , you want use commandButton. first you should Drag and drop panel in form then drop commandbutton in that panel.
very easily...

After a switch of JRE from J8 to J11 JComboBox instances in two different JPanels respectively (both in a JDesktopPane) don't display the popup menu when a respective containing JPanel is not in the focus when a click is happening.
The first click brings focus into the respective JPanel. After that a single click on JComboBox causes the menu to pop up.
This changed when I switched the JRE from 8 to 11.
From the end user perspective it looks like a mess, because most components on the panel don't act like this and correctly do mouse click stuff regardless of the parent panel focus status.
It was this commit for this ticket: JInternalFrame generates UngrabEvent when unselected, which causes JComboBox popup to hide.
After long time i have decided to switch back to Java NetBeans Gui builder. I want to create Management System and keep it professional in terms of User Interface. However am having problem centering the JLabel. My Label takes the full width of the panel and panel is resizable. I want my Label to be resizable and to be centered no matter the size my window. Is this possible? Please I don't want hard coding am using netbeans Gui builder. How can I achieve this? For your information my reputations are too low to post images so nothing to show right now.....
This seemed to work for me.
Drag a panel into your design
Right-click the panel and check the menu checkboxes : Auto Resizing-> Horizontal , and Auto Resizing -> Vertical
Drag a label as the only component
Select the panel. Right-click -> Set Layout -> Border Layout
Select the label. Right-click -> Properties
Choose Center for the both horizontalAlignment and verticalAlignment.
Building a Java GUI application using Netbeans IDE. I have created a JPanel in it. After adding a lot of fields, I want to also add a JscrollPane to it. I have found that if we right click on the pane we have an option to Enclose it in a container that can be Scroll pane or Split pane etc.
The problem is, that the enclosed button is greyed out when I right click on the panel. How should i fix this ?
I had the same issue. After experimentation, it appears you can only use Enclose In if the Layout is set to Free Design.
However, an alternative method I discovered to accomplish the same thing is to create the empty JPanel and the components you want inside it, all at the same level in the TopComponent. Then drag and drop the components you want into the JPanel, using the Navigator window that shows the component hierarchy.
For example, here I've created a JPanel and a JRadioButton as siblings, and then I drag and drop the JRadioButton inside the JPanel, so that the JPanel is the parent.
Result:
I am using Net beans drag and drop GUI and in that i am displaying a chart in a jPanel and i want that when i click a portion of that chart then another panel opens up.I know we can write an event , when we click a whole panel(anywhere in panel) but i just want that when i click the small potion of that chart only then another panel opens up, how is this possible?
Attach a MouseListener to the panel. Detect the events, take action. See How to Write a Mouse Listener for more details.
How to create a rich:modalPanel dynamically? I need to click one button and generate a floating panel. The catch is, if I click the button, there should be created a second panel, and the first one should remain on its place. I've tried using ui:repeat and reRender, but this overwrites the first panel when I generate a second one.
If you have a modal panel opened, you won't be able to click any buttons (unless the button is on the modal panel). RichFaces 4 has a pop-up panel which can be modal or non-modal. Using the non-modal version, you can open multiple pop-ups.
try using
<c:forEach />
For an explanation on why you should use the 'c' tag instead of 'ui' read here.
Alternatively, bind the parent component and create the modal panel programmatically using java. See an example here.
