When setting up dojo connections to onmouseover and onmouseout, and then adding content on mouseover, dojo fires the onmouseout event at once, since there is new content. Example:
dojo.query(".star").parent().connect("onmouseover", function() {
dojo.query("span", this).addContent("<img src='star-hover.jpg'>");
}).connect("onmouseout", function() {
dojo.destroy(dojo.query("img", this)[0]);
});
The parent() is a <td>, and the .star is a span. I want to add the hover image whenever the user hovers the table cell. It works as long as the cursor doesn't hover the image, because that will result in some serious blinking. Is this deliberate? And is there a way around it?
Edit: Just tried out something similar with jQuery, and it works as expected (at least as I expected it to work.)
$(".star").parent().hover(function() {
$("span", this).append("<img src='star-hover.jpg'>");
}, function() {
$("img", this).remove();
});
This will show the image when hovering, and remove only when moving the cursor outside the table cell.
The reason it works with jQuery in your example is because .hover uses the normalized onmouseenter/onmouseleave events. If you were to connect to those, it would work in Dojo as expected. Also, a simulation of .hover for Dojo would be:
dojo.NodeList.prototype.hover = function(over, out){
return this.onmouseenter(over).onmouseleave(out || over);
}
Then you'd just:
dojo.query("...").hover(function(e){ .. }, function(e){ .. });
The differences between mouseeneter and mouseover are why you are seeing the behavior of an immediate onmouseout firing.

In addition to the 'back' button functioning as expected, I need to asynchronously invoke a function to update some db tables and refresh the UI.
Prior to making this post, I did some research and tried the following on this...
<h1 data-dojo-type="dojox.mobile.Heading" id="hdgSettings" data-dojo-props="label:'Settings',back:'Done',moveTo:'svStart',fixed:'top'"></h1>
dojo.connect(dijit.registry.byId("hdgSettings"), "onclick",
function() {
if (gblLoggerOn) WL.Logger.debug(">> hdgSettings(onclick) fired...");
loadTopLvlStats();
});
Since my heading doesn't have any other widgets than the 'back' button, I thought that attaching this event to it would solve my problem... it did nothing. So I changed it to this...
dojo.connect(dijit.registry.byId("hdgSettings")._body, "onclick",
function() {
if (gblLoggerOn) WL.Logger.debug(">> hdgSettings(onclick) fired...");
loadTopLvlStats();
});
As it turns out, the '._body' attribute must be shared by the Accordion widget that I just happen to use as my app's main UI component, and any attempt to interact w the Accordion rendered my entire app useless.
As a last resort, I guess I could simply forgo using the built-in 'back' button, and simply place my own tabBarButton on the heading to control my app's transition and event processing.
If the community suggests that I use my own tabBarButton, then so be it, however there has to be a way to cleanly attach an event to the built-in 'back' button support.
Thoughts?
The following should do the trick:
var backButton = dijit.registry.byId("hdgSettings").backButton;
if (backButton) {
dojo.connect(backButton, "onClick", function() { ... });
}
Remarks:
The code above should be executed via a dojo/ready call, to avoid using dijit's widget registry before it gets filled. See http://dojotoolkit.org/reference-guide/1.9/dojo/ready.html.
Note the capitalization of the event name: "onClick" (not "onclick").
Not knowing what Dojo version you use (please always include the Dojo version information when asking questions), I kept your pre-AMD syntax, which is not recommended with recent Dojo versions (1.8, 1.9). See http://dojotoolkit.org/documentation/tutorials/1.9/modern_dojo/ for details.
I'm creating a seemingly simple dojo 1.8 web page which contains an app layout div containing a tab container and an alarm panel below the tab container. They are separated by a splitter so the user can select how much of the alarms or the tabcontainer they want to see.
Here's the example on jsfiddle:
http://jsfiddle.net/bfW7u/
For the purpose of the demo, there's a timer which grows the table in the alarm panel by an entry every 2 seconds.
The problem(s):
If one doesn't do anything and just lets the table grow, no scroll bar appears in the alarm panel.
If one moves the splitter without having resized the browser window first, the splitter handle ends up in a weird location.
Resizing the browser window makes it behave like I would expect it to begin with.
Questions:
Am I doing something wrong in the way I'm setting things up and that's causing this problem?
How can I catch the splitter has been moved event (name?)
How do I resize the splitter pane to an arbitrary height? I've tried using domStyle.set("alarmPanel", "height", 300) and this indeed sets the height property... but the pane does not resize!
Any help greatly appreciated!
I forked your jsFiddle and made some modifications to it: http://jsfiddle.net/phusick/f7qL6/
Get rid of overflow: hidden in html, body and explicitly set height of alarmPanel:
.claro .demoLayout .edgePanel {
height: 150px;
}
This tricky one. You have two options: to listen to splitter's drag and drop or to listen to ContentPane.resize method invocation. Both via dojo/aspect:
// Drag and Drop
var splitter = registry.byId("appLayout").getSplitter("bottom");
var moveHandle = null;
aspect.after(splitter, "_startDrag", function() {
moveHandle = aspect.after(splitter.domNode, "onmousemove", function() {
var coords = {
x: !splitter.horizontal ? splitter.domNode.style.left : 0,
y: splitter.horizontal ? splitter.domNode.style.top : 0
}
dom.byId("dndOutput").textContent = JSON.stringify(coords);
})
});
aspect.after(splitter, "_stopDrag", function() {
moveHandle && moveHandle.remove();
});
// ContentPane.resize()
aspect.after(registry.byId("alarmPanel"), "resize", function(duno, size) {
dom.byId("resizeOutput").textContent = JSON.stringify(size);
});
Call layout() method after changing the size:
registry.byId("alarmPanel").domNode.style.height = "200px";
registry.byId("appLayout").layout();
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.
I'm using Twitter Bootstrap with fixed layout along with jQuery Masonry on a specific page.
It's working, however starting from the second row the top positions of the divs are miscalculated and are partly covering the elements of the first row.
It looks like the script quits before rearranging the elements.
Strangely, when I open the inspector in Chrome or slightly resize the viewport the divs are jumping to their correct positions. Refreshing the page sometimes helps, sometimes doesn't...
My masonry script:
jQuery(document).ready(function(){
jQuery('.span9').masonry({
itemSelector: '.span3',
columnWidth: function( containerWidth ) {
return containerWidth / 3;
}
});
});
Is this normal behaviour? Should I add window.resize to the above script?
Placing the masonry script in the page itself or in the header, footer doesn't change it's behaviour.
I'm calling masonry.js right after jQuery, before any other Bootstrap js.
Just read the help Section here http://masonry.desandro.com/docs/help.html
The Script runs before all images have been loaded, you have to trigger it after the window loaded
$(window).load(function(){
$('#container').masonry({
// options...
});
});
I'm new with Appcelerator and I encountered an annoying problem regarding layout.
I have to do a menu bar that is very easy to do with plain html (ul>li>a and that's all). The problem is that it seems that all button-related functions are not... customizable. I want buttons to be displayed as plain text, not buttons.
The first thought was to use labels (instead of buttons). But... Is this a right way? I need a menu bar, not a text paragraph! Besides that, the menu is somehow flexible, not like labels.
This is one (of many!) things i tried:
var menu_color = Titanium.UI.createButton({
title:Ti.Locale.getString("menu_color") || "Color",
height:24,
top:10
});
I also added borderWidth:0 (no effect) and backgroundColor:none/transparent with no luck.
Help? :)
I usually use views when I need to create what you described above.
For example:
I use a view with a vertical layout, then add my child views. The child views then have listeners for the click or whatever event.
This allows you to have more control over the formatting. A side effect of this is you will need to create your own "press" ui cue in some cases.
var demo = {win : Ti.UI.currentWindow};
(function(){
//Create the container view
demo.vwMain = Ti.UI.createView({height:100, layout:'vertical', backgroundColor:'yellow'});
demo.win.add(demo.vwMain);
demo.fakebutton1 = Ti.UI.createView({height:40, backgroundColor:'blue',left:25,right:25,borderRadius:5,borderColor:'#000'});
demo.vwMain.add(demo.fakebutton1);
demo.fakebutton2 = Ti.UI.createView({top:5,height:40, backgroundColor:'green',left:25,right:25,borderRadius:5,borderColor:'#000'});
demo.vwMain.add(demo.fakebutton2);
demo.fakebutton1.addEventListener('click', function(e) {
alert('Clicked fake button 1');
});
demo.fakebutton2.addEventListener('click', function(e) {
alert('Clicked fake button 2');
});
})();
create a view with layout property is set to vertical and add label or button which you want.View is like in HTML.Hope you understand.
