For my highchart column graph, I have 2 series and the values can be very close to each other, so overlap can happen.
On exporting, I'm reducing the fontSize property but with different results:
Internet Explorer : The fontSize remains the same. Ugly.
Firefox : The fontSize is reduced. However, the datalabels is now not centered anymore which is ugly
Chrome : Perfect result ! As I would expect. FontSize reduced and centered.
Is there anything I can do or you can do (next release) ?
See the JSFiddle here :
Open it in IE, Firefox and Chrome and export in any format (PNG in my test)
I'm changing the export like that :
exporting: {
chartOptions: {
plotOptions: {
column: {
dataLabels: {
allowOverlap: true,
style: {
fontSize: 6
},
}
}
}
}
}
Thanks in advance.
Actually I found the answer :).
The fontSize should be declared as "6px" and not 6.
so instead of :
style: {
fontSize: 6
},
change it as
style: {
fontSize: "6px"
},
Like that, it works as I expected on IE, FF, Chrome.

How can I change the color of this border.
I have tried using the following in options but that doesn't work.
topBar: {
borderColor: "white"
}
Which did try operation system ? ( Android / iOS ) (I'm using PhpStorm because I'm Full-Stack developer, highly recommend.) By selecting topBar you can go to the source with ctrl+b.
Options.ts
/**
* Change the navbar border color
* #### (Android specific)
*/
borderColor?: Color;
If not both, set the borderHeight. So like this; (from my code)
stack:{
children:[
{
component:{
name: 'app.Main.Shop',
options:{
topBar:{
borderColor:'blue',
borderHeight:2
},
},
}
}
],
options: {..}
}
Result like this;
Hi I wanted to add some Arabic text to my Phaser game. I have the following in the update() function:
this.scoreText = this.add.text( this.world.centerX, this.world.height/5,
"",{nsize: "32px", fill: "#FFF", align: "center"});
this.scoreText.setText("تُفاحة");
This produces strange letters on the screen which are not Arabic. Any ideas?
First off, you shouldn't be adding text in the update() method - this would cause it to be added multiple times (once for each frame, ideally 60 times per second). Move it to the create() method so that it's only added once. You also have a typo in the parameters: nsize should be just size.
function create() {
this.scoreText = this.add.text( this.world.centerX, this.world.height / 5, "", { size: "32px", fill: "#FFF", align: "center" });
this.scoreText.setText("تُفاحة");
}
You can try something like
Import the font in the CSS part in index.html
#import url(https://fonts.googleapis.com/earlyaccess/amiri.css);
Then just declare the style as a variable
var style = { font: "32px Amiri", fill: "#333", align: "center" };
Then in the create function add the text like in this jsfiddle https://jsfiddle.net/albator2018/r2zLtoqd/
There is another manner to do it but like what i've just explained it works fine
I have to perform a very simple task: I want to display a piece of text inside a rectangle and the size of that rectangle should precisely be the width of the text.
In C++, it's fairly easy to do. Just define the QString and apply the QFontMetrics to get its width. Then define the rectangle graphics element to have that size. It's done within five minutes.
I have heard that QML is easier to use. Therefore, I was expecting to solve that problem in less than five minutes. I didn't, and I'm still stuck at it. Here's what I have tried:
Rectangle {
width: myText.contentWidth
height: myText.contentHeight
Text {
anchors.fill:parent
id: myText
font.family: "Helvetica"
font.pointSize: 50
text: qsTr("The string I want to display")
}
}
This doesn't work for some reason I don't understand. I have found a way to do it in a way that doesn't exactly suits my needs:
Rectangle {
width: 100
height: 100
MouseArea {
id: myMouseArea
anchors.fill: parent
onClicked: parent.width=myText.contentWidth
hoverEnabled: true
}
Text {
anchors.fill:parent
id: myText
font.family: "Helvetica"
font.pointSize: 50
text: qsTr("The string I want to display")
}
}
In this case, when I click the rectangle, it gets the correct width. Nevertheless, I am not interested in this solution, because I don't want to have to click to get a rectangle with the correct size.
I want that the rectangle's size gets the correct size whenever myText changes text. The use of onTextChanged in the Text item doesn't work either.
What am I missing here?
As far as I know, Font metrics were made available to developers in Qt 5.4, so they are relatively new, in QML. You got mainly FontMetrics and TextMetrics. A simple usage example:
import QtQuick 2.4
import QtQuick.Window 2.2
Window {
visible: true
width: 280; height: 150
TextMetrics {
id: textMetrics
font.family: "Arial"
font.pixelSize: 50
text: "Hello World"
}
Rectangle {
width: textMetrics.width
height: textMetrics.height
color: "steelblue"
Text {
text: textMetrics.text
font: textMetrics.font
}
}
}
As noted by Phrogz in the comment below, the TextMetrics type does not support measuring wrapped text.
EDIT
For what is worth I've never ever had the need to use metrics in QML. For me content* or painted* properties served the purpose and, as of Qt 5.12, they seem to work fine. Aka the following two solutions generate the correct visual behaviour:
// solution 1
Rectangle {
width: myText.contentWidth
height: myText.contentHeight
Text {
anchors.fill:parent
id: myText
font.family: "Helvetica"
font.pointSize: 50
text: qsTr("The string I want to display")
}
}
// solution 2
Rectangle {
width: myText.paintedWidth
height: myText.paintedHeight
Text {
anchors.fill:parent
id: myText
font.family: "Helvetica"
font.pointSize: 50
text: qsTr("The string I want to display")
}
}
I would prefer those solutions to the usage of metrics for such a simple use case as the one proposed by the OP. For the opposite case - fitting a text in a specific size - a combination of properties can do the trick, e.g.:
Rectangle {
anchors.centerIn: parent
width: 200
height: 30
Text {
anchors.fill: parent
text: "Wonderful Text"
minimumPixelSize: 2
fontSizeMode: Text.Fit
font.pixelSize: 200
horizontalAlignment: Text.AlignHCenter
verticalAlignment: Text.AlignVCenter
}
}
Here the pixel size is simply over the top but the text still fits because a minimum size of 2 is set and the text has a clear fitting policy and clear boundaries, defined by the anchoring.
I'm sure Label component will do the job:
import QtQuick 2.1
import QtQuick.Controls 2.4
ApplicationWindow {
visible: true
Column {
Repeater {
model: [
{"color": "red", "radius": 1},
{"color": "green", "radius": 2},
{"color": "blue", "radius": 3}
]
Label {
padding: 0
text: modelData.color
font.family: "Helvetica"
font.pointSize: 50
background: Rectangle {
color: modelData.color
radius: modelData.radius
}
}
}
}
}
You don't need to use anchors.fill: parent for Text item because size of Text's parent depends on size of Text itself. It's cause binding loop.
This must works fine.
Rectangle {
width: myText.contentWidth
height: myText.contentHeight
Text {
id: myText
font.family: "Helvetica"
font.pointSize: 50
text: qsTr("The string I want to display")
}
}
When hovering over the outer nodes of graph in Cytoscape.js, the qTip dialog is not displayed.
Is there anyway to display the qTip bubbles upon hovering on an outer node? I can have the qtip popup on nodes in the upper half but not much along the sides of the graph. Especially towards the bottom half.
cy.elements('node').qtip({
id: function() {
return this.data('id');
},
content: function() {
return this.data('name') + '<br /><em>$' + this.data('weight') + '</em>';
},
position: {
my: 'bottom right',
viewport: $(etl_cyto_div),
adjust: {
cyViewport: true,
method: 'flip none'
}
},
show: {
cyBgOnly: false
},
hide: {
cyBgOnly: false,
cyViewport: true,
delay: 100
},
style: {
classes: 'qtip-tipsy',
tip: {
width: 16,
height: 8
}
}
});
I suspect your options may be causing the issue. Because this extension is a relatively thin wrapper around qtip, you just use the qTip API and options.
Try leaving options.position.adjust.method default
Try a more permissive options.position.adjust.method; see qtip docs
adjust.cyViewport is expensive (especially on touch) and can be buggy depending on the version of qtip used.
Try all defaults and see if you can reproduce your issue with the events you want. If not, then the issue is due to the set options. If so, please file your example code in an issue
I'm working with this scroller
http://coolcarousels.frebsite.nl/c/2/
I have this setup below.
My issue is I have it set to visible: 4 and I have 4 images, so it doesn't scroll. If I set it to visible: 3 then it works as expected. But I want to show all 4 images in one screen when you open the browser full width on a 1920px wide resolution. So the issue seems to be. If I set visible to the amount of images I have then it stops working.
Is there a way to have all 4 images on screen at one time then still scroll through them?
$(function() {
$('#carousel').carouFredSel({
width: '100%',
align: 'left',
items: {
visible: 4,
start: 0,
},
scroll: {
items: 1,
queue : true,
fx: "scroll",
easing: "swing",
duration: 1000,
timeoutDuration: 3000
},
prev: '.prev',
next: '.next',
auto: {
easing: "quadratic",
button: '.play',
pauseOnEvent: 'resume',
pauseOnHover: true
}
}).find(".slide .plusNav").hover(
function() { $(this).find("div").slideDown(); },
function() { $(this).find("div").slideUp(); }
);
});
try this
items: {
minimum: 0,
},
I have resolved this issue by setting minimum to 0.
items: {
minimum: 0,
Actually, setting the minimum attribute to zero forces the scroll bar to be displayed always irrespective of number of items currently displayed.
This was required for me because, automatic enabling of scroll bars was not working on certain screen resolutions- I had to add 2 more items to make the scroll bar visible which was not the expected behavior.
As a work around, I set minimum: 0 - it resolved the issue.
I was able to do this by editing the source :/
If you comment out this lines 554 & 556 in jquery.carouFredSel-6.2.0.js like this...
// not enough items
var minimum = (is_number(opts.items.minimum)) ? opts.items.minimum : opts.items.visible + 1;
if (minimum > itms.total)
{
// e.stopImmediatePropagation();
// return debug(conf, 'Not enough items ('+itms.total+' total, '+minimum+' needed): Not scrolling.');
}
...it worked for me.
Access the wrapper and set its height (assuming all children have the same height):
var carousel = [your_carousel],
carousel_wrapper = carousel.parent();
carousel_wrapper.height(function(){
return (carousel.children('[child_selector]').length) * [child_height];
});
The thing here is, there will be a weird behavior when the carousel animates. This is because the maximum height was done ((n-1) * child_height) intentionally as a mask, along with an overflow: hidden.
Another option would be to duplicate one of the children, but that isn't semantic.
