I have a map that auto locates the user. I have two buttons and when the screen is centered on the users location the standard order of buttons is in effect top: button 1, bottom: button 2. What I want is when the user slides the map to another location or uses the search that the top button becomes the bottom and vice versa.
I don't really have any idea where to start.
Thank you

I have two panels in unity 2d directly overlapping each other and they use scroll panels so I can scroll down. I have it set so when one is accessed, the other is pulled up, but when they swap the other panel is grey and I cannot interact with it, but when I attempt to scroll the other panel scrolls instead, even though it is hidden and turned off.
I suspect that this is a bug in the code. It's possible, that when the user presses the scroll button in the first panel, and then releases the button, the second panel's scroll button thinks, it's already been pressed by the user, when in fact it isn't.
Set it up in such a way, that when you release the button on a scrollbar (the first scroll bar), it resets the click on the scrollbars connected to it (a second scroll bar).
I have an Ionic 3 app which contains a Leaflet map. This map works great, except for when the user pans westward by swiping from the left side of the screen, which triggers a 'back' navigation.
Is there a way to ignore 'back' swipes from inside a certain div in Ionic 3? I'd rather not use ionViewCanLeave() since I want the user to be able to swipe back from other parts of the view.
Suppose I wish to focus on the state of Colorado in the following chloropeth map:
The typical mechanism is to use the operating-system dependent means of dragging the picture. I am on OS/X so that involves using two fingers to drag the image to the desired new centering location.
However the actual result of that operation is a bounding box is displayed on the image (I can not get a screenshot of it since it disappears)
So then .. how to drag /re-center the Tableau display?
Click onto the small 'play' arrow button on the chart menu in the top left hand corner. A sub menu will pop up where you can select the scroll method you'd like - click and drag is one of these. You can also disable this through the chart options (the small drop down menu on the top right hand corner of the chart).
I've been asked to create an iphone app with a left nav/menu. Since there are no native UI components to use for this, I was wondering what would be the best way to achieve this. The only app that I remember that had this kind of thing was the Facebook app from about 18months ago.
Is there a good 3rd party API to handle this kind of thing?
Description of the left nav: There is a permanent left nav along the left of the screen running the full length of the screen. When the user selects a menu option a UIView/UIViewController slide in from the right side and covers over the menu. A little button is left stuck to the left side of the screen. If the user selects this button the view slides back to the right again, and the leftnav menu appears from underneath the view and it is possible to interact with again.
Where is the problem? just create a UIView with subview containing UIButtons, you have to layout the buttons yourself (calculate the frame). Later you add that leftmenuView to the UiViewCobtroller.
I made a MultiSlider widget using the GWT and the gwt-dnd addon to rate texts. On the screenshot, you can see the slider button with value 50 dragged outside the slider bar. It can't be dropped outside the bar, but it can be dragged outside of it.

Is there a way in GWT to always keep the slider buttons inside the slider bar?
EDIT:
The slider bar is an AbsolutePanel, and it is also the only droptarget for the slider buttons. The slider bar panel is also the boundary panel for the drop controller. Dropping outside of the bar panel is not possible, but dragging is.
Now what I really like to know is if it's possible to keep the mouse pointer on the bar panel. If a button is dragged out of it, it will remain on its old position when dropped (so that's OK). Is it possible to allow only vertical DRAGGING? Can the mouse position be set while dragging?
I've used dragController.setConstrainWidgetToBoundaryPanel(true), and I think dragController.setBehaviorConstrainedToBoundaryPanel(true) does the same thing. For more information, check out the javadoc for your version.
The method you're looking for is defined in AbstractDragController with this signature;
void setBehaviorConstrainedToBoundaryPanel(boolean constrainedToBoundaryPanel);
The boundary panel (often passed in in the first parameter to the drag controller constructor) in this case should be an AbsolutePanel which wraps the slider.
It may also be helpful to visualize the absolute panel if things are not working as expected:
absolutePanel.getElement().getStyle().setProperty("border", "1px dashed red");
