I would like to customize the shape of Kendo Tooltips for a grid.
I saw the example on kendo site, it has the arrow outside the box, and the box has a nice rounded shape.
Working on css, using .k-tooltip I can change width, height, background. But I get a square box with the arrow inside which sometimes overrides part of the text content.
I thought that callout would help but I was not able to get anything.
How can I change shape, image and position of the arrows, shape of the box ?
Moreover, how can I trigger the tooltip only when part of the text in a grid cell is visible ?
Thanks a lot for any hint
regards

I think "arrow" you mean callout. You can turn off callout by:
$(document).ready(function() {
$("#target").kendoTooltip({
callout: false
});
});
About your question "Moreover, how can I trigger the tooltip only when part of the text in a grid cell is visible?"
If I understand you correctly you would like to show tooltip only when there is text with ellipsis (partially visible in the cell), but you don't want to show a tooltip if there is a full text is visible or if there is no text in the cell. If that is the case, you can do this way:
function initializeTooltip(element, filter) {
return element.kendoTooltip({
autoHide: true,
filter: filter,
callout: false,
content: function (e) {
var target = e.target,
tooltip = e.sender,
tooltipText = "";
if (isEllipsisActive(target[0])) {
tooltipText = $(target).text();
}
tooltip.popup.unbind("open");
tooltip.popup.bind("open", function (arg) {
tooltip.refreshTooltip = false;
if (!isEllipsisActive(target[0])) {
arg.preventDefault();
} else if (tooltipText !== $(target).text()) {
tooltip.refreshTooltip = true;
}
});
return tooltipText;
},
show: function () {
if (this.refreshTooltip) {
this.refresh();
}
}
}).data("kendoTooltip");
};
// determanes if text has ellipsis
function isEllipsisActive(e) {
return e.offsetWidth < e.scrollWidth;
}
$(function () {
initializeTooltip($("#yourGridId"), ".tooltip");
});
tooltip in this case is class name of the column that you would like to use tooltip for, but you can call that class anyway you wish. In case if you are using Kendo ASP.NET MVC it will look something like this
c.Bound(p => p.ClientName)
.Title("Client")
.HtmlAttributes(new {#class = "tooltip"});

I have two css classes on a tornadofx label bound to a SimpleBooleanProperty. One which has a background image and a blue border and one which has no background image and a yellow border.
Snippet from View containing label:
val switch: SimpleBooleanProperty = SimpleBooleanProperty(false)
label("my label"){
toggleClass(UIAppStyle.style1, switch.not())
toggleClass(UIAppStyle.style2, switch)
}
Snippet from UIAppStyle:
s(style1){
textFill = Color.YELLOW
maxWidth = infinity
maxHeight = infinity
alignment = Pos.CENTER
backgroundImage += this::class.java.classLoader.getResource("img.png")!!.toURI()
backgroundPosition += BackgroundPosition.CENTER
backgroundRepeat += Pair(BackgroundRepeat.NO_REPEAT, BackgroundRepeat.NO_REPEAT)
borderColor += box(Color.BLUE)
}
s(style2){
textFill = Color.YELLOW
maxWidth = infinity
maxHeight = infinity
alignment = Pos.CENTER
borderColor += box(Color.YELLOW)
}
When switch = false, there is a background image and a blue border. When switch = true, there is the same background image and a yellow border. I'm not finding out how to get the background image to remove. Interestingly enough, if I add a different background image to style2, it changes correctly.
Edit: To remove two toggleClasses and introduce new strange problem:
class MyView : View(){
...
init{
...
row{
repeat(myviewmodel.numSwitches){
val switch = myviewmodel.switches[it]
val notSwitch = switch.not()
label("my label"){
addClass(UIAppStyle.style2)
toggleClass(UIAppStyle.style1, notSwitch)
}
}
}
}
This code snippet does not work for me. However, if I add private var throwsArray = mutableListOf<ObservableValue<Boolean>>() as a field of MyView and add notSwitch to the array, then the same exact code works. It's almost as if notSwitch is going out of scope and becoming invalidated unless I add it to a local array in the class?
I don’t understand why you want to have two different toggleClass for the same control. As you pointed out, the problem in your case is that when the backgroundImage is set, you need to set a new one in order to change it. But in your case, you only have to add the style without backgroundImage first and them set toggleClass with the style with backgroundImage. Like this:
label("my label"){
addClass(UIAppStyle.style2)
toggleClass(UIAppStyle.style1, switch)
}
button {
action {
switch.value = !switch.value;
}
}
Edit: This ilustrate what I'm talking about in comments:
class Example : View("Example") {
override val root = vbox {
val switch = SimpleBooleanProperty(false)
val notSwitch = switch.not()
label("my label"){
addClass(UIAppStyle.style2)
toggleClass(UIAppStyle.style1, notSwitch)
}
button("One") {
action {
switch.value = !switch.value;
}
}
button("Two") {
action {
notSwitch.get()
}
}
}
}
You can put the notSwitch.get() in any action and without trigger that action it does the work. Check how I put it in the action of button Two, but without clicking that button even once, it works.
This is actually some kind of hack, in order to achieve what you want. But I don’t see the reason why my initial solution with true as default value for property shouldn’t work.
Edited to do inverse of status
Here is simple example of a working toggle class using your styling:
class TestView : View() {
override val root = vbox {
val status = SimpleBooleanProperty(false)
label("This is a label") {
addClass(UIAppStyle.base_cell)
val notStatus = SimpleBooleanProperty(!status.value)
status.onChange { notStatus.value = !it } // More consistent than a not() binding for some reason
toggleClass(UIAppStyle.smiling_cell, notStatus)
}
button("Toggle").action { status.value = !status.value }
}
init {
importStylesheet<UIAppStyle>()
}
}
As you can see, the base class is added as the default, while styling with the image is in the toggle class (no not() binding). Like mentioned in other comments, the toggleClass is picky, additive in nature, and quiet in failure so it can sometimes be confusing.
FYI I got to this only by going through your github code and I can say with confidence that the not() binding is what screwed you in regards to the toggleClass behaviour. Everything else causing an error is related to other problems with the code. Feel free to ask in the comments or post another question.
I have 2 nested <div>s, both with tooltip().
When I hover over the
inner <div>, the outer <div> also shows it's tooltip.
I tried to work around this by setting the inner <div>'s title
to an empty string on :hover.
$(inner).hover({
$(outer).attr('title','');
},{
$(outer).attr('title','original title');
});
I created a codepen examplenote: I changed title to 'red' so you can see that the title did indeed change.
Why is it that changing the title doesn't change tooltip's content?
How do we change the Bootstrap Tooltip's content? (this should be a stackoverflow question of it's own)
Answering #1:
By inspecting the elements and watching it change with your JS code, i noticed a attribute on the divs called data-original-title which still holds "blue" when you enter green (this is what the tooltip element reads and displays). By changing your script to
$('#a').attr({"data-original-title": "red"});
the blue becomes red. Does this answer your question?
Use .tooltip('hide') and .tooltip('show')
this was answered in part by #BuddhistBeast, thanks!
$("#b").on('mouseover', function(){
$('#a').tooltip('hide');
}).on('mouseleave', function(){
$('#a').tooltip('show');
});
$('[data-toggle="tooltip"]').tooltip({
animated : 'true',
placement : 'bottom',
container: 'body'});
You can check whether you are currently hovering inside of the inner block
jQuery:
$(document).ready(function(){
var bIsShown = true;
$("#b").on('mouseenter', function(){
bIsShown = true;
}).on('mouseleave', function() {
bIsShown = false;
})
$("#a").on('mousemove', function(){
if(bIsShown) {
$(this).data("bs.tooltip").$tip.removeClass("in");
}
else {
$(this).data("bs.tooltip").$tip.addClass("in");
}
})
$('[data-toggle="tooltip"]').tooltip({
animated : 'fade',
placement : 'bottom',
container: 'body'});
});

Hello i'm working on a project that requires canvas manipulation. I need to draw an image and have to move it within the canvas. Which was not so hard to accomplish.. However i need to change my cursor into "move" when hovering the image like
img{
cursor:move;
}
I couldn't find any way to do this. Any suggestion??
Thanks in advance..
When you drag an Kinetic.Image, you get dragstart and dragend events.
You can change the cursor type in those event handlers:
// starting to drag -- display the move cursor
image1.on('dragstart', function () {
document.body.style.cursor = 'move';
});
// done dragging -- display the regular cursor
image1.on('dragend', function () {
document.body.style.cursor = 'default';
});
Basically you need an element which you can style on the page but with display: none, then put that element onto the canvas like this:
var image = document.getElementById('image');
context.drawImage(image, 0, 0);
I've gotten the icon to change on click, but I need it to change back to the original icon (not stay the new one) when a new icon is clicked.
For instance, say all of my icons are blue. When I click on an icon, I want it to change to a red icon. Then, when I click on a new icon, I want the previously clicked icon to change back to blue.
I can get it to work with mouseover and mouseout, but I really need it to work with click. I think I need to log a new click function, but I'm not sure how.
Here's what I currently have:
function clickFeature(e) {
var layer = e.target;
e.target.setIcon(stop);
info.update(layer.feature.properties);
}
var geojson;
/*function resetHighlight(e) {
geojson.resetStyle(e.target);
e.target.setIcon(arms);
info.update();
}*/
function onEachFeature(feature, layer) {
layer.on({
click: clickFeature
});
}
geojson = L.geoJson(crossingData, {
pointToLayer: function (feature, latlng) {
return L.marker(latlng, {icon: arms});
},
onEachFeature: onEachFeature
}).addTo(map);
You can try to define seprate variable outside of function, that will hold currently clicked marker.
var clickedMarker;
function clickFeature(e) {
if(clickedMarker) {
clickedMarker.setIcon(arms);
}
var layer = e.target;
e.target.setIcon(stop);
clickedMarker = e.target;
info.update(layer.feature.properties);
}
You should get current icon for change to another one. Unfortunately L.marker has no getIcon() method, but you can access it via options.icon.
function clickFeature(e) {
var layer = e.target;
layer.setIcon(layer.options.icon == arms ? stop : arms);
}
Let me explain what I'm trying to achieve. Currently, I have button and want to add image and add text. I have parent div container in which all child div adds dynamically.
Add image button adds img tag with image inside the parent div and add text button adds div containing text inside parent by using append method.
But what I want that when ever I create them, they should place in a specific position which will be common to all. Lets take center of the parent so when ever I add image or text it should create at the center of the parent
Code for adding dynamic image
$(document).ready(function () {
$('#addImage').click(function () {
var url = 'Default.aspx';
var dialog = $('<iframe"></iframe>').appendTo('body');
dialog.load(url).dialog('open').dialog({ modal: true, width: 480,resizable: false ,open: function (type, data) { $(this).parent().appendTo("form"); },
buttons: {
'OK': function() {
var img = document.createElement('img');
$(img).attr("id", "dyndiv" + count);
$(img).attr("width", 60);
$(img).attr("height", 140);
$(img).attr("src", 'Uploads/'+ $get('dvFileName').innerHTML) ;
var $ctrl = $(img).addClass("draggable ui-widget-content").draggable({ containment: '#containment-wrapper', cursor: 'move', snap: '#containment-wrapper' });
objid = "dyndiv" + count ;
count++;
$("#containment-wrapper").append($ctrl);
$(this).dialog('destroy');
},
'Cancel': function() {
$(this).dialog('destroy');
// I'm sorry, I changed my mind
}
}
});
return false;
});
});
At last i got the solution. In the above question I am appending the div, now i am also explicitly defining the position of the div after the append statement above.
