I am new to jquery stuff and have no idea about how to define focus event on sapUI5 controls. I am using 'content' aggregation of 'sap.ui.layout.VerticalLayout', there I need to perform some action whenever user hover or focus on specific content in that vertical Layout. I tried to find focus or hover event for verticalLayout content only but couldn't found it, but I ma sure there must be some jQueryevent that I can use. But I don't know how to use it. Please help me in getting this, Thanks in advance.
I understood what to do, actually I was adding 'sap.ui.layout.Grid' as a content of VerticalLayout, so I solved the asked problem using 'attachBrowserEvent'
Below is the snippet-
var oGrid = new sap.ui.layout.Grid({
hSpacing: 1,
vSpacing: 0.5,
content: [ oFields ]
}).attachBrowserEvent('mouseover', function(oEvent){
//to do code
});

I'm trying to use the AG-Grid for my project and I've been trying to play around with it for a while now, but one problem I came across with this grid is that I can't easily make the columns to auto resize whenever the div or browser resizes like a fluid layout.
I know there is the .api.sizeColumnsToFit() function to use which will do it once it's called, but this would mean I will to manually add a listener or some sort to the window to check if it has been resize and call it if it has?? Is there a better way to achieve this??
Thanks
Try calling sizeColumnsToFit whenever the grid onGridSizeChanged event fires. The following will run when the grid first loads/ or data adjusts (onModelUpdated) and when the grids size changes.
i.e
this.gridOptions = <GridOptions>{
onModelUpdated: () => {
this.gridOptions.api.sizeColumnsToFit();
},
onGridSizeChanged: () => {
this.gridOptions.api.sizeColumnsToFit();
}
};
I got a app that shows multiple pages, which are dragable. As the content of those can get very long I want to show only the page-name and limit the height of the page to about 50px on beginDrag() and reset the height to auto on endDrag(). Unfortunately this doesnt work, the styles get just ignored. I think this happends because react-dnd needs to keep the proportion of the elements so it can handle the drop-targets and knows which component is at which position. Is there any other way to accomplish this?
If you use a dragPreview then it will use that instead of the screenshot-ed component, similar to what he does in the tutorial (http://gaearon.github.io/react-dnd/docs-tutorial.html):
componentDidMount: function () {
var connectDragPreview = this.props.connectDragPreview;
var myPlaceholder = <Placeholder /> // A fake component with the height you want
myPlaceholder.onload = function() {
connectDragPreview(myPlaceholder);
}
}
(Note that you'll have to inject the connectDragPreview through the collector like he did as well)
I'm not quite sure I understand the problem but may be connectDragPreview can help you?

I'm trying to configure the width for Alfresco.util.PopupManager.displayPrompt() but I don't see how to do it.
YUI Dialog has a width property, but the only config that I've managed to see, defaultDisplayPromptConfig object, doesn't seem to pay much attention to my messing with it.
Specifically, I tried setting Alfresco.util.PopupManager.defaultDisplayPromptConfig.width but it didn't work :)
I'm also trying to style up the panel I'm loading (create-site style injected panel), but it does not work for now.
Is there a way to configure the PopupManager Prompt object?
TIA
If you look at the source for Alfresco.util.PopupManager.displayPrompt() contained in alfresco.js then you'll see that the method creates an instance of YAHOO.widget.SimpleDialog, which does support a width property.
The problem is that displayPrompt() takes only specific configuration options which it passes through to the SimpleDialog, so adding an additional width parameter to your config will not have any effect, as you can see.
// Create the SimpleDialog that will display the text
var prompt = new YAHOO.widget.SimpleDialog("prompt",
{
close: c.close,
constraintoviewport: c.constraintoviewport,
draggable: c.draggable,
effect: c.effect,
modal: c.modal,
visible: c.visible,
zIndex: this.zIndex++
});
// Show the title if it exists
if (c.title)
{
prompt.setHeader($html(c.title));
}
// Show the prompt text
prompt.setBody(c.noEscape ? c.text : $html(c.text));
// Show the icon if it exists
if (c.icon)
{
prompt.cfg.setProperty("icon", c.icon);
}
// Add the buttons to the dialog
if (c.buttons)
{
prompt.cfg.queueProperty("buttons", c.buttons);
}
// Add the dialog to the dom, center it and show it.
prompt.render(parent);
prompt.center();
prompt.show();
I like the idea of enhancing the function to support a width property and possibly others, but in the meantime you are best off using SimpleDialog directly in your own code, modifying the above to add a width parameter.
I'm breaking my head since a whole day now but cannot find a solution, I hope someone can help me.
I'm trying to create a simple SmartGWT ListGrid with checkboxes and for some reason I can only check checkboxes but not uncheck them.
Once the checkbok is checked there is no way to uncheck it.
Below the code I'm using to create the grid.
Here I first instantiate the grid that is populated later with a call to the server.
Any idea of what I'm doing wrong? Anything wrong with the initialisation maybe?
Thanks in advance!!

It's not clear how your code sample above is related to a clickable checkbox - your code doesn't make any attempt to create a field with checkboxes??
All you need to do to get a clickable checkbox is declare a field of type "boolean" and setCanToggle(true). setCanToggle(true) allows it to be toggled with one click without needing to have editing enabled for any other fields.
I've been through the Dojo docs as well as the API and tried Google but can't find a solution to my problem, I hope anybody here can help me out.
I'm trying to create a dijit.form.select programmatically (using Dojo 1.4) and connect to the "onClick"-event of the widget.
Here's a part of my code:
var dataSelect = new dijit.form.Select({
id : "myselect",
name : "myselect",
labelAttr: "label",
labelType: "html"
},
"selectid");
dataSelect.addOption({value: "value", label: "first item label"});
dojo.connect(dataSelect, "onClick", function() {
alert("clicked!");
});
What it does: A select-box is created replacing an input-field with the ID "selectid", an option "first item label" is created. Everythings all right until here.
Then I connect to the "onClick"-event of the select, which is supposed to load more options via AJAX (but will just display an alert for testing purposes in this example).
The problem: When I click on the little arrow next to the dropdown, the event is fired (OK). But when I click on the select box itself (the area containing the option), the event is NOT fired the first time I click it (unless I clicked on the arrow before).
When I click the select box a second time (and every time after that), the event will fire!
I've tried to use "onFocus" instead of "onClick" which does work, but then the dropdown will not open when first clicked, even if I use the "openDropDown"-function (which does work when connecting to "onClick"!).
Is it me, did I run into a Dojo bug or is it a strange feature I just don't get?
Any help is appreciated.
Greetings,

Here is a cross-browser solution:
var sizeSelect = new dijit.form.Select({
id: "sizeSelect",
name: "state",
options: size,
onChange: function(val) {
dojo.style(dojo.byId("textInput"), {"fontSize":val});
}
}, "sizeSelect");
Try to connect not to the widget itself but to it's dom node:
dojo.connect(dataSelect.domNode, "onclick", function() {
alert("clicked!");
});
Select (which extends _HasDropDown) has fancy code to handle:
mouse down on select widget
mouse move to one of the options
mouse up
Maybe that's canceling the click event.
Maybe you can connect to _loadChildren() instead.
The root cause for this issue is that the _onDropDownMouseDown method of dijit._HasDropDown will manipulate the dom node, which cause the e.target of onmousedown and onmouseup changes for the first initialization.
As we know, the onclick event will be triggered only when the target of onmousedown and onmouseup are the same target.
So in this case, the onclick event is not triggered.
It seems that in Dojo 1.5, the problem still remains.
