How to customize Google Map markers in Flutter? - dart

markerList.forEach((marker) {
mapController.addMarker(marker);
mapController.onInfoWindowTapped.add((marker) {
print(marker.id.toString());
});
});
How do I call the above callback for when info-window is tapped?

Figured it out...needed to add a void callback :D

Can you Listen for ShowBottomSheet on Close?

Imagine creating a bottom sheet as follows:
final PersistenBottomSheetController bottomSheetController = showBottomSheet(...);
How do I execute logic upon closing that bottom sheet?
It is a bit unidiomatic for Flutter widgets:
bottomSheetController.closed returns a Future when closing the bottom sheet, which allows for this logic:
bottomSheetController.closed.then((value) {
// this callback will be executed on close
});
Works with await as well:
await bottomSheetController.closed;
// code below this call will get executed upon close
final PersistentBottomSheetController<dynamic> bottomSheetController = scaffoldKey.currentState!.showBottomSheet((context) {
return Container();
});
await bottomSheetController.closed.then((value) {
// the code for working on drawer close
});

In high chart how to add event for label click

In high chart there is an event for clicking on the bar. But bar is small in height it is impossible to click on it. Hence I want the event in high chart for further processing.
E.g. I want the event for month name in following example.
Thanks In advance.
If you don't want to use JQuery you can use it as follows
chart.xAxis[0].labelGroup.element.childNodes.forEach(function(label)
{
label.style.cursor = "pointer";
label.onclick = function(){
alert('You clicked on '+this.textContent);
}
});
complete code at http://jsfiddle.net/t07ok5v3/5/
Alternate solution, maintained since Highcharts v3 is to use Custom Events plugin. Plugin adds a lot of new event, natively not supported by Highcharts.
Demo: https://jsfiddle.net/BlackLabel/Utx8g/963/
Events are added the same way as official events in Highcharts, and we don't need to re-inspect every release the DOM:
xAxis: {
labels: {
events: {
click: function () { ... }
}
}
}
I get Error: Object doesn't support property or method 'forEach' when running the solution from Malay Sarkar in Internet Explorer. Here's a workaround I used which works in both Chrome and IE.
for (let i = 0; chart.xAxis[0].labelGroup.element.childNodes.length; i++)
{
chart.xAxis[0].labelGroup.element.childNodes[i].onclick = function(){
alert('You clicked on '+this.textContent);
}
});

Drillup Button Click Listener - Vaadin Charts

I know that drillup button works on the client side, but is there any way to know when that button is clicked?
In the ColumnWithLazyMultiLevelDrilldown class you can see example of using ChartDrillupListener.
Chart chart = new Chart(ChartType.COLUMN);
chart.addChartDrillupListener(new ChartDrillupListener() {
#Override
public void onDrillup(ChartDrillupEvent event) {
log("ChartDrillupEvent");
}
});

Show loading highstock

I try to show a loading effect (chart.showLoading()) when my zoom is finished.
I used the events : "afterSetExtremes", "setExtremes", "redraw", but they don't work.
Example :
{
events : {
redraw : function(){
chart.showLoading('Loading...');
}
}
}
And I don't know where I put my chart.hideLoading() function.
I want the same effect : lazy-loading but without async request.
Am I forced to use an async request ?
In setExtremes use chart.showLoading('Loading...'); and in afterSetExtremes use chart.hideLoading();

jqueryUI Sortable: handling .disableSelection() on form inputs

example: i have an un-ordered list containing a bunch of form inputs.
after making the ul .sortable(), I call .disableSelection() on the sortable (ul) to prevent text-selection when dragging an li item.
..all fine but I need to re/enable text-selection on the form inputs.. or the form is basically un-editable ..
i found a partial solution # http://forum.jquery.com/topic/jquery-ui-sortable-disableselection-firefox-issue-with-inputs
enableSelection, disableSelection seem still to be un-documented: http://wiki.jqueryui.com/Core
any thoughts?
solved . bit of hack but works! .. any comments how i can do this better?
apply .sortable() and then enable text-selection on input fields :
$("#list").sortable({
stop: function () {
// enable text select on inputs
$("#list").find("input")
.bind('mousedown.ui-disableSelection selectstart.ui-disableSelection', function(e) {
e.stopImmediatePropagation();
});
}
}).disableSelection();
// enable text select on inputs
$("#list").find("input")
.bind('mousedown.ui-disableSelection selectstart.ui-disableSelection', function(e) {
e.stopImmediatePropagation();
});
A little improvement from post of Zack - jQuery Plugin
$.fn.extend({
preventDisableSelection: function(){
return this.each(function(i) {
$(this).bind('mousedown.ui-disableSelection selectstart.ui-disableSelection', function(e) {
e.stopImmediatePropagation();
});
});
}
});
And full solution is:
$("#list").sortable({
stop: function () {
// enable text select on inputs
$("#list").find("input").preventDisableSelection();
}
}).disableSelection();
// enable text select on inputs
$("#list").find("input").preventDisableSelection();
jQuery UI 1.9
$("#list").sortable();
$("#list selector").bind('click.sortable mousedown.sortable',function(e){
e.stopImmediatePropagation();
});
selector = input, table, li....
I had the same problem. Solution is quite simple:
$("#list").sortable().disableSelection();
$("#list").find("input").enableSelect();
The following will disable selection for the entire document, but input and select elements will still be functional...
function disableSelection(o) {
var $o = $(o);
if ($o.find('input,select').length) {
$o.children(':not(input,select)').each(function(x,e) {disableSelection(e);});
} else {
$o.disableSelection();
}
}
disableSelection(document);
But note that .disableSelection has been deprecated by jquery-ui and will someday go away.
EASY! just do:
$( "#sortable_container_id input").click(function() { $(this).focus(); });
and replace "sortable_container_id" with the id of the element that is the container of all "sortable" elements.
Quite old, but here is another way:
$('#my-sortable-component').sortable({
// ...
// Add all non draggable parts by class name or id, like search input texts and google maps for example
cancel: '#my-input-text, div.map',
//...
}).disableSelection();
