Is it possible to visualize JFR events on chart? Sure I can browse them in log section but I'd like to visiualize them on chart also.
A good example would be "Machine total" attribute from "CPU Load" event.
If it is possible how to achieve it?
Use the Designer View:
Window -> Show View -> Designer (Unsupported)
Open a JFR file
Go to the appropriate tab
Click the red stop button in the designer view
Use context menus in either the editor view or designer view to modify the existing GUI
Use the designer view and New Group or New tab to add new GUI (close and reopen the JFR file to view the new tab structure)
This is both unsupported and undocumented, but is however how the standard JFR GUI is built. I'm trying to find an online video where either I or someone else has demoed this..
(Your example with "Machine total" is already visualized though, both on General/Overview and Threads/Overview)
Good luck!

I'm developing an E4 plugin application which contains 2 perspectives and a couple of views. I've added these views to the Eclipse Window->Show View -> Other.. menu and they open accordingly. If I open a view that is already opened in another perspective I would like the application to focus on that perspective instead of opening a new view in the current perspective.
Is it achievable? I already unchecked "multiple" property in the part descriptor but it still doesn't work.
'Window > Show View' just opens a view in the current perspective using the IWorkbenchPage.showView method.
There is no support for switching to a different perspective.
I've just migrated from Eclipse to JetBrains IntelliJ IDEA and I find it very annoying when it comes to using designer. When I create a new GUI form the designer works fine for some time. Then suddenly after switching to other class or after closing and reopening IntelliJ it shows me XML code only and I have no option to switch to designer mode. This time I have form with three buttons and IntelliJ shows me XML with three notifications at the top "missing mnemonic: name_of_a_button" despite that I didn't use any and never wanted to. By the way even if it works fine I don't have that switch at the bottom to toggle between designer and text mode. Why is that?
We have two options:
(1) Disabling this particular inspection by clicking the icon at the right of the message;
(2) Going to the button's Component Properties panel, "Text" property,clicking on the lamp icon and providing a mnemonic for the text. (image berllow)
I am trying to create a view in eclipse. I want my view to contain a Textfield and a button. the action is triggered by clicking on the button and some processing will be done on the inserted query in the textfield. can anyone suggest me a link to a tutorial or example doing that?
Thanks
You can create two quick samples that together show you what you've asked for. You do that by using the new project wizard to create a plugin project. One of the last wizard pages has a list of templates to choose from. If you create a plugin using the "with a view" template, you'll see how to create a view. Go back and create a second plugin with the "multi-page editor" template and you'll see examples of buttons, their event handlers and text fields. It should be easy to see how to code up the buttons and texts in the view.
I'm using Eclipse 4.2 (Juno) for Java EE and just installed WindowBuilder plug-n. At this time I'm building Java SE Application with Swing components.
The Palette is completely empty (no widgets). Is it a sign of incomplete installation or have I (hopefully) missed something obvious?
I was able to select New -> Other -> WindowBuilder -> Swing Designer -> JPanel.
Not even sure what other information I need to provide.
Thank you in advance for your help.
EDIT:
I installed via Help -> Install new software Followed these instructions.
What throws me off is that in Eclipse Community Forum I found a post which answering a similar question states: "What you are seeing is the expected behaviour. Until you actually edit a UI class using WindowBuilder, those views will be empty.". I do not know how to interpret it.
UPDATE: Problem solved
When I created a new JFrame via Create new visual classes icon I finally got Design view as well as Palette full of components and normal Structure view.
The Palette view in Eclipse is tied to the currently active Editor. So if you don't have an Editor or you have selected and focused on the Palette view, it will be empty. So leave the palette view open, then create a JFrame java class. Then right-click the Java Class and make sure you are opening it in the WindowBuilder editor. Once the WindowBuilder visual editor is open, and you also have the Palette open, you should see the wigets populated there.
Check if pallet is open in view pannel (parallel to console, progress and all), if it is open close that, then pannel will appear automatically in windowsBuilder tool.
When you open a dialog in Eclipse, where is a form layout, you can see that when you hover your mouse over some item, its label or space between them, there's an auxiliary arrow shown. Screenshot:
My question is: is there any (simple) way to achieve the same in Java with SWT and JFace?
Regards
No there is no standard way to achieve this through SWT or JFace, as it is not a built in feature. It is not that difficult to add on your own though.
Have a look at this ConfigurationBlock.java file from the PDE source. This class is the base for all option blocks in PDE preference pages. This exact same code snippet is also used by JDT but it has a different copy in OptionConfigurationBlock.java.
The method that gets called for each combo control is ConfigurationBlock#addHighlight(..), which is responsible for adding the highlight when the control is in focus or when mouse is hovering over its label.
