I'm trying to make an application that looks like the Messages app from Apple.
The NSSplitView has toolbars on both subviews of the NSSplitView. They blend in with the top toolbar. It's similar to the NSToolBar but that doesn't work in NSSplitView's. Is there any way to make this work?
I tried the CNSplitView but it doesn't provide the proper effect. Is there another way of doing this that I'm missing?
The interface i'm going for is here:
Instead of using NSToolbar, you can add your own views to the top of subviews in the NSSplitView to achieve this after hiding the existing titlebar.
NSWindow's titleVisibility can be used to hide the built-in titlebar, and by setting the window's styleMask to include NSFullSizeContentViewWindowMask you can cause the split view to take up the full height of the window.
To get the blur effect like toolbars/Messages you can use NSVisualEffectView in the top views. Setting the material NSVisualEffectMaterialTitlebar will give the same look as standard titlebars.
And finally, you can put NSStackViews inside the visual effect views, and then place the titlebar controls in there.
(And depending on the content that is below your fake toolbars, you might want to look into NSScrollView's contentInsets property to allow the scroll view to show all of the content, but still be able to scroll under your toolbar).

I have been trying to disable scroll bars in a text area using the code:
ScrollBar scrollBarv = (ScrollBar)textArea.lookup(".scroll-bar:vertical");
scrollBarv.setDisable(true);
But all I get is a null pointer for "scrollBarv". What am I missing?
You can't disable a scroll bar in a text area via lookups like you are trying to do.
A lookup is CSS based, which usually means it will only work after a CSS application pass has been applied. Generally, for a lookup to work as expected, a layout pass also needs to be applied on the parent node or scene. The logic in the JavaFX layout handlers for complex nodes such as controls may modify the CSS and nodes for the controls.
To understand how to apply CSS and perform a layout pass, read the relevant applyCss() documentation.
So you could do this:
textArea.applyCss();
textArea.layout();
ScrollBar scrollBarv = (ScrollBar)textArea.lookup(".scroll-bar:vertical");
scrollBarv.setDisable(true);
But even then, it would not do what you want. Because it is just a one-time call. If the user types new text into an empty TextArea until it fills the area, then a scroll bar will show up, and if the user deletes text in the text area, the scroll bar will be removed. And the new scroll bar which shows up wouldn't be found when you did your lookup because it would not have existed at that time.
Generally, the preferred alternative to performing lookups to nodes is to apply CSS style classes with the style class defining the desired attributes of the node regardless of the state it is in (and using psuedo-classes if state based CSS definitions are required). However, that probably won't work in this case as I can't see a definition for a disable attribute in the JavaFX CSS reference guide. Perhaps you might manage what you need via the visibility property, though that is unlikely as visibility is a bit different from disable.
The behavior for controlling the scroll bars is internally coded in the TextAreaSkin (which in Java 8 is not part of the public JavaFX API). You could copy or subclass the TextAreaSkin to customize its behavior and then attach your customized skin to your node. This is really the "proper" way to customize internal control behavior in the way in which you wish. A discussion of the detailed steps to achieve this is outside the scope of this answer.
But, in the end, I'm not sure how useful the behavior you desire is. Rather than disabling the vertical scroll bar, you could just disable the entire TextArea, which would be fine for most similar use-cases. Though, perhaps your use-case is different somehow in requiring only the vertical scroll bar to be disabled.
I would like to achieve with QML a menu with a single menu item, like chrome does it. It has this button with those three horizontal bars and when you click it you get a single menu. Recent versions of firefox also follow the same principle. It allows not to waste too much horizontal space in the GUI of the application, unline usual menus which take up the whole width of the window.
I did not manage to reproduce exactly this GUI with QML. From what I saw you can either use a QML ApplicationWindow, and then a MenuBar, but then it takes the whole width of the window... Or have a toggle button to trigger the menu, then use a standalone Menu and its popup() method, but then it pops-up directly under the cursor, not exactly under the button to open the menu, which doesn't look good. That's really more abusing the mechanism for a context menu.
I could make a fake menu which would be a custom widget in my window but then it could not expand beyond my application window. Such a behaviour is almost required because I'll put this button on the far right of the window, as chrome does it.
Is it possible to achieve exactly that behaviour in pure QML (no C++)?
What I did for now is the last option that I mentioned: fake menu in the window. It's drawing using the canvas which enables me to make it a little pointy arrow from the menu to the menu toggle button, as done also by firefox.
The minus as I said is that the menu cannot go out of the window, plus everything is very manual (mouseover effect for menu items...), so I'm still interested in other solutions.
EDIT: ok after some time I realized a big plus of my approach: I can put custom widgets, not only labels in the menu. So I think it's absolutely the right approach now.
I am building this form: http://codepen.io/anon/pen/gFoIG/
and so far I am satisfied. Unfortunately I have some issue that I seem not able to fix.
First of all, I want to enforce the label positions beside their respective inputs. Now the form breaks down easily (with the opera emulator for smartphone and tablet, the privacy label goes below the check, but I want that it stays beside it)
The other issue that I have is that I want it to fall back gracefully when there are small screens, like placing the second image below the first and placing the input controls one below the other and take the full screen width to be bigger and easier to interact with, but so far I only was able to break the layout with my tests.
This issue: the the form layout breaks, the internal control (input, button, etc) go outside the container div. How do I enforce the container to keep everything inside? I've experimented with blocks, floats and whatever, but if the layout breaks, the input boxes usually go outside the gray rectangle.
Last issue: If I insert this form inside an existing website (for example, a page in wordpress) the layout get completely destroyed because influences from the theme style. How do I enforce my style on my form, keeping it isolated from the other styles? I can think of the iframe as a solution, but it is the only one? It is a good practice?
Anyone can help me with that?
You might want to take a look here. Its a site I just set up to explain an approach to responsive using a jQuery plugin to manage redoing layout. I think it could work for your example quite easily. Also because it can target a container div at any depth in a web page, it could be helpful in the scenario where the layout you want to reflow is inside a 3rd party container (as long as you can run script on the page).
Hi I want to create an application has this sort of function:
http://looklet.com/create
In this application when you click the button (or some tilelist) on the right the model on the left update accordingly. I wonder how they achieve this. Originally i think it's some sort of image-only pop-up window but then pop-up window seems to update the entire view.
Then I think it might be only change view state, but then I still confused how it can be done using view state.
Flex expert please give me some hint !
Looks like transparent images drawn on Canvas. Each piece must have predefined offset and draw order.
Probably just images placed on one or more Canvas, with the z-order controlled for depth.
The body stays the same, so shirts probably have their own placement properties, as do skirts, underwear, hosiery, etc. as well as backgrounds, faces, etc.
I'm working on a Flex 4 application and I started customizing the interface with skins to give a whole new look.
So, I've created two scrollbar skins in Flash Catalyst (one horizontal, one vertical).
Its working great when I test the application through Catalyst so I took it and imported it on Flash Builder, copied the components and defined the new skins in my css file for the HScrollbar and VScrollbar.
The skin is working, all the buttons are ok. But, the scrollbar isnt resizing for some reason. It remains in the same height I've designed it to be regardless of the content it is bound to.
It scrolls the content in all the ways it should be but it doesnt resize and the thumb isnt getting all the way down.
Also I've noticed the following.
I have a custom component acting as a list. It extends Group and contains a Scroller. So at one place of the application the Scrollthumb is getting lower than on another place where the same custom list is used.
I also have to mention that this scroller works perfectly without a custom skin.
Anyone else having similar problems?
Okay, I know you posted this a while ago but I have been scouring the internet for days looking for why the scrollbar's thumb wasn't scaling like the default scrollbar.
There are a couple things to check, first is there a set height on your thumb's skin?
If not, and this is what I was overlooking, go to your scroller skin and at the point where you add the vertical and horizontal scrollbar set the "fixedThumbSize" property to false.
I suppose that your graphic elements are defined as every single part of the scrollbar (top arrow, bottom arrow, track, etc...): in this case you should check that the elements dimensions are not fixed... they should be in % to be able to change the dimensions based on the container.
