I'm working on a plasmoid for KDE Plasma and can't figure out how to implement a scrolling header bar, similar to ones you see at the bottom of the screen on news channels. I want to have a line of text which horizontally scrolls inside a colored box at a fixed speed, looping forever and seamlessly starting over once it reaches the end. I figured out the basic part of the looping transition, allowing the text to move outside of its box then come out the other end:
Rectangle {
width: myItem.width
height: myItem.height
color: myColor
Text {
width: myItem.width
wrapMode: "NoWrap"
maximumLineCount: 1
color: theme.textColor
text: "Whatever goes here."
SequentialAnimation on x {
running: true
loops: Animation.Infinite
NumberAnimation { from: -myItem.width; to: myItem.width; duration: 1000; easing.type: Easing.InOutQuad }
PauseAnimation { duration: 250 }
}
}
}
But this doesn't take into account the length of the text string in order to adjust the start / end position and duration to its real width. It also requires moving the text completely out of bounds then back in, leaving the box empty for one frame... I wonder if there's a way to make it connect seamlessly. It also doesn't notice when I resize the plasmoid and adapt the animation range, only the scale detected at the start is taken into account. How do you suggest redoing that definition to work around scale issues and get consistent results with any box size and text length?

I'm making a vehicle's instrument cluster in QML and wanted to align the speed labels to the curve in such a way that they are all the same distance away from it. To do this, I used pathview to set up an arc, then used the text delegate to have the text appear in the right places. The reason it's not working exactly as intended is that some text is larger than other (for example '0' takes less space than '100') which causes some variability in distance between the text and the circle I'm trying to align it with. How can this be done better?
Here's the snippet of what I have got working so far:
Component {
id: spdLabel
Text {
font.weight: Font.Normal
font.pixelSize: 28
color: "white"
text: model.index
visible: model.index % spdMarkInterval == 0
}
}
PathView {
anchors.fill: parent
z: 0
model: topSpeed + 1
delegate: spdLabel
path: Path {
PathAngleArc {
centerX: (dialGauge.x + dialGauge.width)/2
centerY: (dialGauge.y + dialGauge.height)/2
radiusX: 140
radiusY: 140
sweepAngle: 270
startAngle: 135
}
}
}
Here's what the result looks like:
Since it is the center of text elements that's anchored a constant distance away from the arc, the distance between the text edge and arc varies.
Thanks for any help!
I'm trying to get something in a ScrollView to expand in width to fit the screen. The ScrollView is anchored to the main window.
For example purposes, a Rectangle:
ScrollView {
anchors.fill: parent //mainWindow
Rectangle {
color: "light grey"
height: 1000
width: mainWindow.width
}
}
But when the vertical scrollbar appears, it obscures the Rectangle. I can sort of fix it by using a magic constant:
width: mainWindow.width - 20
But what if somebody has bigger scrollbars on their computer? Also it leaves an ugly empty space on the right when the vertical scrollbar is invisible.
Is there a way to automatically learn what the available space is inside of a ScrollView?
There is no need to explicitly adjust to scroll bar. You can just make it to fill the entire available parent space or so. And if you want specify margins:
ScrollView {
id: scrollView
anchors.fill: parent // mainWindow ?
anchors.centerIn: parent // anchoring as asked
anchors.margins: 20
contentItem:
Rectangle {
id: rectScroll
width: scrollView.viewport.width // set as viewport
height: 1000 // set to what you need
}
}
The original issue was solved mainly due to the width property of Rectangle set to parent.parent.width or scrollView.viewport.width as it is more adequate. The latter is definitely better, as long as the width of precisely viewport of scroll area and not the parent width (which in general not guaranteed to contain only this ScrollView).
I am customizing the title of the Magnific popup/lightbox to include more than one row of content by using the 'change' callback, and modifying the content of
this.content
within the callback. It is working correctly, except for the fact that if the image within the popup is very tall, or the window re-sizes to a smaller height, the calculation that Magnific is doing to adjust the 'max-height' of the image seems to only take into account a single row of text for the title.
Does anyone know what is needed to adjust the max-height calculation of the image to take into account a taller title box?
Thank you
** Edit
A quick hack to jquery.magnific-popup.js around line 461 in the "updateSize:" callback has allowed me to get around this problem. It seems reasonable to for this popup/lightbox to accept a max height in percentage so that it doesn't fill the screen.
Here's my change, I'd appreciate some feedback if possible. Thanks!
updateSize: function(winHeight) {
if(mfp.isIOS) {
// fixes iOS nav bars https://github.com/dimsemenov/Magnific-Popup/issues/2
var zoomLevel = document.documentElement.clientWidth / window.innerWidth;
var height = window.innerHeight * zoomLevel;
mfp.wrap.css('height', height);
mfp.wH = height;
} else {
mfp.wH = winHeight || _window.height();
// ########################################
// CHANGE IS RIGHT HERE TO FORCE 80% height
// ########################################
mfp.wH *= 0.8;
}
// Fixes #84: popup incorrectly positioned with position:relative on body
if(!mfp.fixedContentPos) {
mfp.wrap.css('height', mfp.wH);
}
_mfpTrigger('Resize');
},
You can limit the max height of the image in the resize callback, which will allow more room for the title:
$('a.magnific').magnificPopup({
type: 'image',
callbacks: {
resize: function() {
var img = this.content.find('img');
img.css('max-height', parseFloat(img.css('max-height')) * 0.95);
}
}
});
I'd like to add my contribution. As I wanted to include both titles and descriptions to images. This meant that I couldn't fit all this information in the viewport space. The description was cut off and I was left with a scrollbar.
#alexantd - I tried your callback addition which only works when the window is being resized.
#ajhuddy - Your solution worked perfectly for me. I was able to fit the text in fine. Though the image was considerably small with a lot of space at the top.
I adjusted the padding as to regain 40px space to display a slightly larger image. Here's my CSS to do so. The CSS below allowed me to reduce images to 0.85 (85%).
.mfp-img {
padding: 0px 0px 40px !important;
}
.mfp-close {
margin-top: -40px;
}
else b.wH=a||v.height()**,b.wH*=.9**;b.fixedContentPos
Problem
I use the flexslider carousel to a number of images to show. What I want now is, when the browser has a certain width drop a break, which for example is incidental to 768px 2 images are shown. Currently you see an image at a certain width but half and wants to these points with javascript / jquery to give many pictures there must fully show.
So my question is, how I can make an if statement for when the browser width is for example 768px width, is must show two images...
$('.flexslider').flexslider({
animation: "slide",
animationLoop: true,
itemWidth: 320,
itemMargin: 0,
minItems: 2,
maxItems: 5,
start: function(slider){
$('body').removeClass('loading');
}
});
Check code on JSFiddle
You can use an if statement for widths like this:
if ($(window).width() < 960) {
alert('Less than 960');
}
else {
alert('More than 960');
}
... and to contain that, you might like to combine your document ready function with a window resize function.
$(document).ready(myfunction);
$(window).resize(myfunction);
function myfunction() {
// Pace the if/else here, do whatever
}
In terms of showing two images it think you should be able to be achieve that by setting slide widths and offsets in the flexslider function - or with css. here are the options i'm talking about:
itemWidth: 490, // or whatever is 1/2 of your width
itemMargin: 30, // experiment here!
minItems: 1, // or 2

I am working on a mobile application and using sencha touch charts. By default horizontal bar chart is fitting exactly into screen. If there are more number of bars,then bars are appearing very thin and looking odd. I want to fix bar width to have uniform look and feel irrespective of number of bars being displayed. No matter even user need to scroll down to see entire chart. I have tried below option in series configuration, but it did not work.
style : {
size : 30
}
Please help me.
Thanks,
Nag.
am able to change the bar width by setting barWidth option in touchcharts-debug.js by refering to the following link
http://docs.sencha.com/touch-charts/1-0/source/Bar.html
but the axis labels are not rendering properly labels are fitting into screen
I tried this code in my interactions to render the labels, it's working fine
{
type: 'panzoom',
showOverflowArrows: false,
//axes: ['bottom'],
axes: {
bottom: false,
left: {
startZoom: 2
}
}
}
