I am currently learning flutter and trying out different things. Not too long ago I discovered the app "Reflectly". I wonder how it is possible to create such an "add button" with animation.
Reflectly add button
Two possibilities for implementation have crossed my mind.
With the help of a stack widget and 4 shapes, 2 for the BottomBar and 2 for the button. The button would have an animation and enlarge and also move. However, this sounds a bit complicated for such a button.
The whole thing is a drop menu, but I don't know how to get such a shape with matching animation. Especially, these two things don't make it easy for me to imagine how to implement such a button.
Does anyone have an idea?
You can achieve this by the following
Create 2 different paths. 1 is for the center button and the second one is the custom shape that you wish to see as the output when the button is clicked. Then use an animated builder and change shape when clicked

i'm trying to manage different state of a simple push button on an OS X application : When the user click on it, and when the user release the click.
Currently i set my button type by NSMomentaryLightButton
NSMomentaryLightButton When the button is clicked (on state), it
appears illuminated. If the button has borders, it may also appear
recessed. When the button is released, it returns to its normal (off)
state.
This type of button is best for simply triggering actions because it
doesn’t show its state; it always displays its normal image or title.
This option is called Momentary Light in Interface Builder’s Button
inspector
I thought it was the good way, but when i print my button status, it's like a toggle button than the push button that i set. As you can see on exemple gif
To sum up, How can i have a real push button behaviour ? Call function when the user click on it, and when the user release the click.
Thank,
You don't want to use buttons for piano keys. First, they are non-rectangular, and they don't act as buttons do: neither single-action push-button, nor toggle switches. You are interacting in a custom way, with a custom view, meaning the NSButton control hierarchy isn't called for. Instead you're subclassing NSView and capturing low-level mouse events as detailed here:
https://developer.apple.com/library/prerelease/content/documentation/Cocoa/Conceptual/EventOverview/HandlingMouseEvents/HandlingMouseEvents.html#//apple_ref/doc/uid/10000060i-CH6-SW1
You found this yourself as you detailed in your own comments, but I wanted to make sure you had a higher level point of view. It's even possible, and probably best, to consolidate all of the piano keys into a single view, and let the keys themselves be rendered using NSBezierPath and perform mouse hit detection using containsPoint:
https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSBezierPath_Class/#//apple_ref/occ/instm/NSBezierPath/containsPoint:
This is a lot more work but the only way to make a truly professional looking piano simulation. Then you can render the keys with whatever outline, fill, and labeling you need without the limitations of built-in button shapes and layout. You could even have the bottom edges of the keys slightly rounded, for example, or apply a shiny texture.
I just want to make a moving button , Is there a way to do that in GWT? Thanks in advance.

Out of the box, you can use a DialogBox to display your button. DialogBox can be moved around, but you will need to display something in a Caption that is used for dragging.
Another option is to use PopupPanel. It can be completely invisible (no Caption), but you will have to implement dragging functionality on your own. The advantage is that a PopupPanel floats on top of all the other layers in your UI.
Finally, you can simply add dragging functionality to a regular button. Just remember to check for the boundaries so that a user cannot drag your button outside of the visible browser area - or obscure some important elements of the UI.
I'm currently trying to create a small notepad app, and i'm in need of help. I am using a Tabbed View Application. Say we had a view that has two text fields for Name and short description, and then a button beneath saying "Create Note".
How can I make this button change the view to my editor/notepad view that does not have the tabs at the bottom?
Thanks
If you are using storyboards, which I assume that you are, what you will want to use are triggered movements called segues.
To create one, right-click on the button and drag the line that appears to the second view, and then release.
It should look like this:
Then, when you release, a gray box will appear, with a list of segues. You can find out what each one does online, and as you get more advanced you can develop custom ones.
However, use Modal as a basic one to begin with.
Hope this helps,
Will.
PS. In the future, try and make your questions more specific, and do some research before you ask a question. It's important that you gain a good reputation on Stack Overflow if you want your questions answered properly.
For example: "I create 2 button, one for character to move foward and one for character to jump".
Problem is: when press that two button only one of them can work.
So can anyone tell me how to make that 2 button work together?
One solution could be replacing your 2 GUI buttons to GUI Textures. Textures are placed in a Rect so in your update you have to check if your "touch" event is within one of these positions.

I need to add a control button with a "rectangle" zoom or what's called the boxZoom function in leaflet. I know that the function can be used when pressing shift and drawing a rectangle but I need a button that gets clicked and then the user can draw a rectangle which is used a bounds for the boxZoom function. I thought this wouldn't be difficult but I just can't figure it out.
Bonus points if you could tell me how to link other functions, e.g. of leaflet.draw, to my own buttons. I need to create my own button toolbar, so I need to be able to attach different functions to the buttons and would like to use already existing functions.
There isn't a one size fits all solution for this (thus the reason for L.Control.BoxZoom being its own plugin). You'll need to add buttons with click handlers, then read the API of Leaflet or the plugin you're integrating with (e.g. drawing) to find how to toggle the behavior.
The Leaflet.EasyButton plugin does a good job of encapsulating the creation of single button controls and click handlers in an easy way, and may be a good starting point if you're struggling with getting started.
