Is there a way to add img src tag in programmatic for a dijit.form.button?
In declarative, we can do something like this :
<div dojoType="dijit.form.Button"><img src="images/img.png"/></div>
In this case, the dijit button is completely replace by the image.
If I try something like this, the image not replace button but appear in :
var button = new dijit.form.Button({
showLabel : false,
label : "Validate",
iconClass : "alphaIcon validateIcon",
})
Your help would be very appreciated.
Thanks in advance
I think your approach should be to do exactly what you did AND create custom css to modify the appearance.
myIconButton.dijitButton .dijitButtonNode {
border: 0;
background-image: none;
background-color: transparent;
box-shadow: none;
}
var button = ... // same as above
dojo.addClass(button.domNode, 'myIconButton');
To directly answer your question, you could create your own button widget with a custom template that only had the image source.
dojo.declare("MyIconButton", [Button], {
templateString: '<div><img src="${imageSrc}"></img></div>'
});
NOTE: I didn't test this approach and there may be other modifications that you would need in MyIconButton because the base Button class would be expecting other nodes in the template.
The following will do what you want
this.button1.attr('label','<img src="' + this.constants.packagePrefix + '/images/button1.gif"/>');
I found it here:
http://mail.dojotoolkit.org/pipermail/dojo-interest/2009-August/038353.html
I have been using a class with background-image for buttons. This really made it hard to dynamically set the image. So, I had success using this:
domStyle.set(myButton.iconNode, 'background-image', 'url(images/icon.png)');
The trick was using iconNode, rather than domNode or containerNode.

I use kendo-ui dropdown.
I add some ovveriding-css, and it works well.
.k-animation-container {
//this is popup that is html is rendered out of the page element
//so it cannot be selected by id / panaya class / panaya element
.k-popup.k-list-container {
.k-item,
.k-item.k-state-selected,
.k-item.k-state-focused {
background-color: transparent;
color: $darken-gray-color;
margin-left: 0;
margin-top: 0;
}
}
}
The problem is, that while each dropdown has other input element instance, the list has one instance that is hidden and when you click any combo - is shown near the currently clicked combo.
What say - when you ovveride the list-container style - dows it for all of the combooxes.
Is there any solution for this issue?
Well this is a known problem, for every popup kendo renders independent div with class k-animation-container
You can try with this solution suggested on telerik forum:
k-animation-container
$("#spreadsheet").on("click", ".k-spreadsheet-editor-button", function(e) {
var animationContainer = $(".k-animation-container").last();
// use some custom conditional statement that will determine if this is the correct list popup, e.g. check what's inside the popup
if (true) {
animationContainer.children(".k-popup").css("min-width", 200);
}
});
Didn't try it my self, gl.
One solution I found was to use
popup: {
appendTo: $(some parent with ID)
}
This way we can manipulate styling of that particular .k-animation-container.
But this doesn't work on every widget, unfortunately.
My team find a great solution:
There is an option to give the input-element custom id.
Then you can select the list-container by the custom id you gave +'list' str.
Now, if you want to get the k-animation-container, you can select the list element and then request its parent.
Code sample:
The input element:
<span
kendo-multi-select
id="my-type-dd"
k-options="$ctrl.getVMultySelectConfig()"
k-ng-model="$ctrl.selectedTypes"
></span>
Selectors:
If you need only the k-list-container and not must the k-animation-container, you can do that by css:
.k-animation-container #my-type-dd-list {
//this is popup that is html is rendered out of the page element
//the id is the id you give to the element + '-list'
&.k-popup.k-list-container {
padding: $space-normal 0 $space-small $space-small;
box-shadow: 3px 3px 1px rgba(0, 0, 0, 0.1);
}
}
If you need the k-aniamation-container you need to select it by jQuery becouse css doesn't have parent selector:
var kAnimationElement = $("#my-type-dd-list").parent();
I want to add QToolButton inside the QLineEdit.
I want to clear the text of QLineEdit control on that button click.
For example how in google image:
I have looked :
This StackOverflow article
But still not solved my issue.
Thanks in Advance.
This behaviour is available as a direct property to QLineEdit since Qt 5.2:
https://qt-project.org/doc/qt-5/qlineedit.html#clearButtonEnabled-prop
QLineEdit *edit = new QLineEdit(this);
edit->setClearButtonEnabled(true);
You can add a custom QAction with your self-defined icons to the QLineEdit:
https://qt-project.org/doc/qt-5/qlineedit.html#addAction
QLineEdit *edit = new QLineEdit(this);
QAction *action =
edit->addAction(QIcon("/path/to/icon"), QLineEdit::ActionPosition::LeadingPosition);
connect(action, &QAction::triggered, this, &ThisObject::doSomething);
//Create QToolButton:
QToolButton *clearButton = new QToolButton(this);
QPixmap pixmap(":/new/AppResource/images/clear_button.png");
clearButton->setIcon(QIcon(pixmap));
clearButton->setIconSize(pixmap.size());
clearButton->setCursor(Qt::ArrowCursor);
clearButton->setStyleSheet("QToolButton { border: none; padding: 0px; }");
clearButton->hide();
Connect Signal-Slot:
connect(clearButton, SIGNAL(clicked()), this, SLOT(clear()));
connect(this, SIGNAL(textChanged(const QString&)), this, SLOT(updateCloseButton(const QString&)));
Visible on Text Enter into serach box:
clearButton->setVisible(true);
Is there a way of manually loading the view from within the controller, after say some animation was triggered first? The scenario I have is the previous page content sliding up, after that the view would be updated when being off-the screen and once ready - slides back down with the new view from the new controller.
I've got already the router set up, but it just instantly replaces the view whenever the new controller is called.
Any fiddle if possible please?
Code in Controller shouldn't manipulate DOM, directives should. Here is directive to prevent preloading content of element with "src" (by browser's parser) and show content of element only after loading, and before loading show splash with spinner:
directive('onloadSrc', function($compile) {
return function(scope, element, attrs) {
element.bind('load', function() {
var parent = $compile(element[0].parentElement)(scope);
if (!element.attr('src') && attrs.onloadSrc) {
element.attr("src", attrs.onloadSrc);
// replace this dirty hardcode with your template for splash spinner
var spinner_div = $compile('<div style="z-index: 100; width: '+element.attr('width')+'px; height: '+element.attr('height')+'px; display:block; vertical-align:middle;"><img src="/img/spinner.gif" style="position: absolute; left: 50%; top: 50%; margin: -8px 0 0 -8px;"/></div>')(scope);
attrs.onloadSrc = "";
parent.prepend(spinner_div);
element.css("display", 'none');
attrs.xloading = spinner_div;
}
else {
if (attrs.xloading) {
attrs.xloading.remove();
attrs.xloading = false;
element.css("display", 'block');
}
}
}
);
}});
To use this directive, leave empty attribute src of element and fill attribute onload-src.
Angular has animations build in in unstable branch, which should perfectly fit your scenario.
Just check out http://www.nganimate.org/angularjs/tutorial/how-to-make-animations-with-angularjs.
ng-view directive has build in 'enter' and 'leave' animations.
Check you this sample: http://jsfiddle.net/nFhX8/18/ which does more less what you'd like to achieve.
What I want to do is when i click on my image, i want the kendo dorpdownlist to propose me some options. Is it possible ?
I tried to replace the defautl template of dropdownlist with CSS without success.
Here i try simply to replace the default black arrow of the dropdownlist, with no success.
SOURCE : http://docs.kendoui.com/getting-started/web/appearance-styling?x=54&y=12
-----------------------------HTML
<select id="customList" class="k-widget k-dropdown"></select>
-----------------------------Javascript
$("#customList").kendoDropDownList().data("kendoDropDownList");
-----------------------------CSS
#customList .k-icon .k-i-arrow-s
{
background-image:url('../../resources/img/components/addtab.png');
}
But what i really want to achieve is to replace completely the default template of the kendo dropdownlist and to have instead my image.
There are a couple of question to keep in mind:
The HTML element that contains the arrow is not a descendant of customList but descendant of a sibling. This is because KendoUI decorates original elements with others.
You are only re-defining background-image but you there is two additional CSS attributes that you need to redefine: background-position and background-size since it is defined in Kendo UI CSS files for offsetting k-i-arrow-s icon.
So, you should either do:
span.k-icon.k-i-arrow-s {
background-image:url('../../resources/img/components/addtab.png');
background-size: 16px 16px;
background-position: 0 0;
}
if you are ok with redefining every additional elements OR you do it programmatically defining a CSS:
.ob-style {
background-image:url('../../resources/img/components/addtab.png');
background-size: 16px 16px;
background-position: 0 0;
}
and a JavaScript:
var list = $("#customList").kendoDropDownList({...}).data("kendoDropDownList");
$(list.wrapper).find(".k-icon.k-i-arrow-s").addClass("ob-style");
CSS3 supports multiple background images, for example:
foo { background-image: url(/i/image1.jpg), url(/i/image2.jpg); }
I'd like to be able to add a secondary image to an element with a class though.
So for example, say you have a nav menu. And each item has a background image. When a nav item is selected you want to layer on another background image.
I do not see a way to 'add' a background image instead of redeclaring the whole background property. This is a pain because in order to do this with multi-backgrounds, you would have to write the base bg image over and over for each item if the items have unique images.
Ideally I'd be able to do something like this:
li { background: url(baseImage.jpg); }
li.selected { background: url(selectedIndicator.jpg); }
And have li.selected's end result appear the same if I did:
li.selected { background: url(baseImage.jpg), url(selectedIndicator.jpg); }
Update: I also tried the following with no luck (I believe backgrounds are not inherited..)
li { background: url(baseImage.jpg), none; }
li.selected { background: inherit, url(selectedIndicator.jpg); }
That is, in any case, not the way CSS inheritance works. inherit implies that an element should take on the attributes of it's parent element, not previous declarations affecting the same element.
What you want has been proposed as a way to make CSS more object-oriented, but the closest you will get is with a pre-processor like SASS.
For now you actually just have to re-state the first image along with the second.
I don't think this is possible, I think you'd have to redefine the whole rule every time.
For example, you could just add a "wrapper" around every item that has the initial background, with the actual item having a transparent background. Then add the background on the item itself when it's selected.
Additive CSS rules still aren't possible as far as I know.
You could try applying the second image to the ::after pseudo element:
li { background: url(baseImage.jpg); position: relative; }
li.selected::after {
content: '';
position: absolute;
width: 100%;
height: 100%;
background: url(selectedIndicator.jpg);
}
I had the same need as you recently.
I finally thought about it and solved using css variables.
::root { --selectdropdown: url( '../elements/expand-dark.svg' ); }
select.gender.female { background-image: var(--selectdropdown), url( '../elements/female-dark.svg' ); }
When you resetting the attribute, just specify the variable again in the list!
