I'm working on a mapping app using ionic and leaflet. Note that I am not using the leaflet angular directive, I am using straight JS for the leaflet map (I know, I know...).
The initial state in my app loads the leaflet map just fine. If I switch to another state and back to the map everything is also fine. However, if I launch the app, switch to a different state and open a modal window in that state, then return to the original state, the map is broken and displays a number of grey tiles. The map will not update until the browser window resizes or the orientation of the mobile device is changed.
Here's a demo on Plunker: http://plnkr.co/edit/w67K2b?p=preview. To reproduce:
Click the button at the right side of the navbar which will take you to a different state.
Click the 'Back to map' button to go back to the original state. The map looks just fine.
Click the button in the navbar again.
Click the 'Open modal' button and then close the modal.
Click the 'Back to map' button and you will see that the map is now broken.
I've seen other people report issues with grey tiles, which typically can be resolved with a call to:
map.invalidateSize()
Unfortunately this does not resolve my issue. I'm pretty much a newb, but I think the problem is that when the modal opens, the invalidateSize() method in the leaflet source code is run, since the map div is not visible, the 'size' gets set to x:0, y:0 which ends up breaking the map when I transition back to the original state.
I'm not really sure where to go from here. Perhaps I can use JS to dynamically resize the div and trick leaflet into thinking a resize event has occurred? How would I do this? Any other thoughts?
Thanks!

I use React MUI and some components disable my draggables.
I have put draggables on my page, that works perfectly.
When my draggable is dragged, I change some nodes in the page.
I'm on React MUI and I use tooltips, modals and menus on that page. After opening one of them and close it, no draggables can be dragged anymore. I mean that changing some nodes in the page makes that the drag ends directly.
Is there an event inserted or something like that that ends the drag action if an element is changing in the page ?
I found a workaround.
Actually this happens on Chrome and Safari only. Adding a setTimeout of 10ms before changing the DOM makes the job.
In a Codenameone app, I'm trying to develop a carousel with a thumbnail list at the bottom. I've used Tabs control to display files (of diff types like images, video, text, button etc) in carousel style in the center of a form and another Tabs control to display thumbanail images (of the first carousel files) at the bottom of the form. When a user selects a thumbnail image in the bottom carousel, corresponding component should be displayed in the first carousel.
hi.add(BorderLayout.CENTER, mainCarousel);
hi.add(BorderLayout.SOUTH, bottom_tab);
bottom_tab.addSelectionListener((i1, i2) -> {
// bottom_tab.getTabComponentAt(i2).addPointerPressedListener((i) -> {
mainCarousel.getTabComponentAt(i2).setVisible(true);
mainCarousel.getTabComponentAt(i2).repaint();
// });
});
But the component not getting displayed in the central carousel.
Also, I tried to capture the event addPointerPressedListener, but it's not getting fired when I select a thumbnail image.
You can't set tab components to visible/invisible to show/hide them. That won't work. I'm guessing that what you want is a horizontal list for the bottom UI similar to the answer here.
I would suggest using pointer released always. Notice that this will only get delivered to focusable components or the form. To make sure you get the event you can register a pointer release listener on the form.
I have figured out how to make animations happen by using $stateChangeStart or $stateChangeSuccess in a controller or in my main apps $stateProvider but I can't get it to work as I intend to.
I would like to initiate a solid color bar that wipes over the screen and then wipes back the other direction showing the content. I imagine that when I click a menu link the animation begins(wiping over the current page), once at full-width -> the static page or data-binded page/controller is loaded and rendered and then once that is complete the animation swipes back the other way revealing the new page content.
I need help understanding how to make sure that every time a link is clicked: the first animation happens/ page is loaded/ and the next page revealed.
I'm working on a web app that uses lots of modal overlays with scrollable content in the modal . On touch devices, and in particular on Android, the mobile browser wants to scroll the body content behind the modal instead of the actual scrollable content area within the modal. Or, if the content does scroll, when it hits the top or bottom of the scrollable area, the scrolling then continues on the body. I don't want the body to scroll at all under any circumstances when the modal is visible/active.
I tried to prevent this with the following code but it seems to have no effect (in this case, $context is the document root):
$context.on('touchmove touchstart touchend', '[data-modal-content]', function(e) {
e.stopPropagation();
});
Anyone have other ideas/insight?
Is there anything wrong with the provided z-index of your elements? Maybe the Modal itself or an inner container isn't stacked on top of the body-text
The map shows if it just a normal map but does not show when the location service is added to show the users current position
I had tried the fix for this
<script>
$("#dashboard").on("next", "click", function(event, ui)
{
map.invalidateSize(false);
});
</script>
Leaflet map not displayed properly inside tabbed panel
but this does not work. It only shows a tiny piece of the map in the top left hand corner and also destroys the initial zoom and is zoomed out to the max.
If i pan the map it will briefly show a section of the map and then disappear. The added marker is set though.

I was able to get it to work by wrapping the whole map creation in a function mapInit() and then i just called that function on the button click that showed that section of the page. Zoom , location, options and the display of the map all work 100%.
