Sencha Touch DataView and highlighting a row when selected - sencha-touch

I have a dataview list inside a container which is displaying items correctly inside the view. However, whenever I click on an item it isn't getting highlighted.
I've added this to the view containing the DataView list:
onItemTap: function (container, target, index, e) {
var me = this;
me.callParent(arguments); // WARNING: without this call, the row will not become selected
}
I've read that the item won't get selected if I don't have the above. I can see this event being fired ok too. If I debug through the Sencha Touch source code, I can see the CSS class x-item-selected is being added to the DIV wrapping the list item, but there is no highlighting of the row. This works fine on normal lists so what am I missing?
Updated CSS which seems to work.
.x-dataview .x-data-item.x-item-selected
{
border-top-color: #006bb6;
background-image: -webkit-linear-gradient(top, #0398ff, #007ad0 3%, #005c9d);
color: white;
}

By default Sencha Touch Dataview doesn't provide any highlighting. Add a background or something to .x-item-pressed or .x-item-selected class and you will get the desired effect.

How about setting the selectedCls in the config block?

Is it possible to dynamically add a slide to an existing Materialize Carousel?

I am able to create a carousel as described here. The carousel appears and works properly.
Later on I would like to add an additional slide:
$(".carousel").append('<a class="carousel-item active" href="#six!"><img src="http://lorempixel.com/250/250/nature/6"></a>');
However, this does not appear to work as the slide does not get added to the carousel.
Is adding slides to an initialized carousel not supported or is this an issue on my end?
Sure it is. I haven't seen any solution in the internet. I believe that there might be a better and smoother solution but this one is mine.
All you need to do is after adding your new items remove the initialized class from already initialized main carousel div and reinitialize it.
//init carousel
var slider = $('.carousel');
slider.carousel();
//add a new item
slider.append('<a class="carousel-item active" href="#three!"><img src="http://lorempixel.com/250/250/nature/3"></a>');
//remove the 'initialized' class which prevents slider from initializing itself again when it's not needed
if (slider.hasClass('initialized')){
slider.removeClass('initialized')
}
//just reinit the carousel
slider.carousel();

I had the same problem, but I'm using the slider. (http://materializecss.com/media.html#slider)
To resolve this, it was necessary to clear all items, re-add items with the new one, and then re-bind the slider.
Follow example: https://codepen.io/troits/pen/QvdZov
let itens = [];
function addItem(){
$('.slides').empty();
$('.slider > .indicators').detach();
itens.push(createItem());
for(i in itens){
$('.slides').append(itens[i]);
}
$('.slider').slider();
showItem(i);
}
function showItem(i){
$('.slider > .indicators > .indicator-item')[i].click();
}

How to properly anchor popovers in Bootstrap 3x

If you look at the bootstrap demo that is hosted here And scroll down to the demo that has all 4 buttons. Now click on the left popover, it shows properly. However, When I shrink or extend the screen the popover is no longer anchored to the proper point. Is there a way around this?
This has to do with the container property for the popover.
http://jsfiddle.net/yvkhbw4b/1/
See the attached example. Show both popovers then resize the window from xs breakpoint to sm breakpoint. You will see the top item will seperate from the button as the container defaults to body. (I'm also setting it to body though options). The second item is attached to the parent div so that one remains attached to the element even though the breakpoint changed.
Documentation on popover options
Appends the popover to a specific element. Example: container: 'body'.
This option is particularly useful in that it allows you to position
the popover in the flow of the document near the triggering element -
which will prevent the popover from floating away from the triggering
element during a window resize.
$('#btn1').popover({
'container': 'body'
});
$('#btn2').popover({
'container': '.col-sm-12'
});
Potential Fix: you could add the following code. Currently only handles bottom aligned popovers but you can add options for other alignments.
$(window).resize(function () {
$('.popover.in').each(function () {
var el = $('[aria-describedby="' + this.id + '"]');
if ($(this).hasClass('bottom')){
$(this).css('top',el.offset().top + el.outerHeight(true));
}
});
});

How to Hide Right Arrow in QMenu in Qt?

Can anyone please tell me how to hide the right arrow for the QMenu items. I tried using the stylesheet. But it didn't works.. Please Help.
MyStylesheet.qss
QMenu::right-arrow[hide="true"]
{
image: url(Resources/MenuRight.png); //am using an unavailable image so that it will return empty.
}
and in code i have set the property as,
menuItem->setProperty("hide", true);
but in the stylesheet(shown below) if i remove the dynamic property, then it is working fine. the background color of the right arrow changes to red.
QMenu::right-arrow
{
background-color: red;
}
You can use the menu-indicator property in the stylesheet of the item.
Here with a QPushButton:
QPushButton::menu-indicator{ width:0px; };

Dynamic menu button items in TinyMCE

I have a custom menubutton in my tinyMCE editor that uses specific HTML elements elsewhere on the page as the menu items. I use a jQuery selector to get the list of elements and then add one each as a menu item:
c.onRenderMenu.add(function(c,m) {
m.add({ title: 'Pick One:', 'class': 'mceMenuItemTitle' }).setDisabled(1);
$('span[data-menuitem]').each(function() {
var val = $(this).html();
m.add({
title: $(this).attr("data-menuitem"),
onclick: function () { tinyMCE.activeEditor.execCommand('mceInsertContent', false, val) }
});
});
});
My problem is that this only happens once when the button is first clicked and the menu is first rendered. The HTML elements on the current page will change occasionally based on user clicks and some AJAX, so I need this selector code to run each time the menu is rendered to make sure the menu is fully up-to-date. Is that possible?
Failing that, is it possible to dynamically update the control from the end of my AJAX call elsewhere in the page? I'm not sure how to access the menu item and to update it. Something using tinyMCE.activeEditor.controlManager...?
Thanks!
I found a solution to this problem, though I'm not sure it's the best path.
It doesn't look like I can make tinyMCE re-render the menu, so instead I've added some code at the end of my AJAX call: after it has updated the DOM then it manually updates the tinymce drop menu.
The menu object is accessible using:
tinyMCE.activeEditor.controlManager.get('editor_mybutton_menu')
where mybutton is the name of my custom control. My quick-and-dirty solution is to call removeAll() on this menu object (to remove all the current menu items) and then to re-execute my selector code to find the matching elements in the (new) DOM and to add the menu items back based on the new state.
It seems to work just fine, though tweaks & ideas are always welcome!

Dojo grid inside titlePane not getting painted until the browser is resized

I have an dojo enhanced grid inside a title pane which inturn in Tabcontainer. I am creating a tab container dynamically and painting the title pane which contains grid. For the first time the grid is painted properly but if i close the tab and again try it to open a tabcontainer title pane is painted but grid inside the titlepane is not painted (or rather its not visible) until i do a browser resize.
So anybody have faced similar kind of issue? Please let me know the solution for this.
I tried resize(), update() & startup() methods on grid nothing worked out.
I am kind of stuck please share your thoughts on this.
Thanks,
Vikram
I had the same problem and found a workaround by doing a dojo connect like:
dojo.connect(Datagrid,"_onFetchComplete",DataGrid,"_resize");
So it should automatically be resized, when DataGrid finished loading data.
Hope I could help.
Greeting, Simon
Have you tried setting an absolute height on the Grid?
Which browsers did you try? (I experienced various problems with DataGrid in TabCointainer using IE)
You must call the TabContainer.layout() each time its container is changing size. For doing this, you could 1) monitor DOMEvents onunderflow and onoverflow on containing DOMNode or 2) when container becomes visible (once-n-forall).
Reason why a window.onresize event fixes it is, that the TabContainer hooks on said event and calls its own layout.
In your situation, where the TabController fiddles with TabContainer's panes, there may be missing a 'layoutChildren' somewhere. Optimally, you should place the grid as the first on only child to tab.
After the grid is deployed, it will take an absolute, calculated height - 'inherited' from the TabContainer. This is fired once the TabContainer chooses to resize or instructed to do so.
Manually, you should be able to implement these lines - after re-opening a tab. The script is taken from _Grid.js to illustrate
var grid = dijit.byId('MYGRIDID');
require(["dijit/layout/utils"], function(layerUtils) {
layoutUtils.layoutChildren(grid.domNode,
grid._contentBox,
[grid.tablist, {
domNode: grid.tablistSpacer,
layoutAlign: titleAlign
}, {
domNode: grid.containerNode,
layoutAlign: "client"
}]);
grid._containerContentBox = layoutUtils.marginBox2contentBox(grid.containerNode,
{
domNode: grid.containerNode,
layoutAlign: "client"
});
// note this line in particular
grid.selectedChildWidget.resize(grid._containerContentBox);
}
My issue
I had a similar situation as yours:
Grid is in a titlepane (closed by default).
Grid can be destroyed and re-created on the fly.
Issue appears when user:
opens the pane.
closes the pane.
re-creates the grid.
re-opens the pane.
grid is not visible, until browser window is resized!
My solution
My approach was to force a resize() on my grid whenever the title pane was being opened.
I used code like this, in a place where I had access to both the grid and the panes:
var titlePane = registry.byId("title-pane-id");
var handle = aspect.after(titlePane, "toggle", function(deferred) {
if (titlePane.open) {
grid.resize();
}
});
The dojo/aspect doc
Don't forget to remove the aspect from your grid if you destroy it.
I did this on dojo v1.8.1
My solution is too easy: define on declaration of grid the bold parameter write here:
grid = new EnhancedGrid({id: 'MyIDgrid',
store: dataStore = new ObjectStore({objectStore: myStore}),
structure: structureGrid,
plugins: pluginGrid,
style : 'width: 725px; height: 350px',
autoWidth : true,
**autoHeight : false,height:'200px',**
elasticView : '2'
}, document.createElement('div'));
this resolve all!
Enjoy!
style="height: auto;" will fit the purpose.
