I am using jsPdf to export table data as pdf file, I have about 50 columns in my table.
but i am not able to see all columns in pdf. only few col are visible rest seems out of page, but there is no scrollbar in pdf file.
please suggest how to get a horizontal scrollbar on pdf page.
Below is my code snippet :
exportPDF(myTableHeaders,myTableData) {
const pdf = new jsPDF();
pdf.setFont("helvetica");
pdf.setFontSize(6);
;
let headerConfig = myTableHeaders.map((header) => ({
name: header.fieldName,
prompt: header.label,
width: 30,
align: "center",
fontSize: 6,
padding: 0,
}));
pdf.table(20, 30, myTableData, headerConfig);
pdf.save("pdf.pdf");
}
Below is snap :

I am using jsPDF to convert HTML components into a PDF.
Below is the code for that,
var doc = new jsPDF({orientation: 'l',unit: 'px',format: [1250,1100],compress : true});
let component=document.getElementById('document');
doc.html(component,{
margin: [10, 0, 50, 0],
callback: function (doc) {
doc.save("report.pdf");
},
x: 0,
y: 0,
});
The resulting PDF looks like.
PDF PROBLEM
I expect jsPDF to move the component to the next page whenever its find that the size of the component is bigger than the rest of the current page.
Is it possible to reverse a master timeline within GSAP? I know you can reverse a timeline that is not nested.
Here's the code:
// hide copy content divs
const hideCopyContentDivsTl = new TimelineMax()
hideCopyContentDivsTl.to(copyContentDivs, 1, {
height: 0,
width: 0,
autoAlpha: 0
})
// shrink copy wrapper div
const shrinkCopyWrapperTL = new TimelineMax()
shrinkCopyWrapperTL.to(copyWrapperDiv, 1, {
width: '2%',
height: '4%'
})
// fade remove bg and change to white
const fadeLargeBgImgTl = new TimelineMax()
fadeLargeBgImgTl.to(largeImage, 1, {
backgroundColor: "#fff"
})
// the master timeline to manage the parts
const masterTimeline = new TimelineMax({paused: true})
masterTimeline.add(hideCopyContentDivsTl)
.add(shrinkCopyWrapperTL)
.add(fadeLargeBgImgTl)
// assume that there is a mechanism to change the state of playVideo between true and false
if (this.state.playVideo === false) {
console.log("should play: ", masterTimeline)
masterTimeline.play()
} else {
console.log("should reverse: ", masterTimeline)
masterTimeline.reverse()
}
I can get it to play forwards, just not in reverse. Do I need to tell the browser where to start in the timeline so that it can play in reverse?
The problem is with my code and not with GSAP. I have new timelines created on every click. How will it reverse something that it doesn't have a previous reference to? The solution would be to create the timelines outside of the click event and then based on the state, play forward or reverse the animation.
I have an app written initially for iPhone 6 symulator which has a componend syled with following example values:
const styles = StyleSheet.create({
headerNav: {
width: 40,
height: 40
},
headerLogoImage: {
width: 140,
height: 140
},
footerNavText: {
padding: 15,
fontSize: 25
}
});
Unfortunately when I launched the app on iPad symulator, the size proportions completely collapsed. I know that there is something like PixelRation but documentation is very limited and unclear.
Any idea / suggestions how can I translate these width / height / padding & fontSize to proper values using this PixelRatio class?
fontSize needs to be divided by PixelRatio.getFontScale(). This will account for different screen densities in iOS and Android.
footerNavText: {
fontSize: 25 / PixelRatio.getFontScale()
}
https://facebook.github.io/react-native/docs/pixelratio.html
You could do something like:
footerNavText: {
padding: PixelRatio.get()*3,
fontSize: PixelRatio.get()*4
}
Check what get() method returns for each of the devices you wish to use and style accordingly.
For more info visit https://facebook.github.io/react-native/docs/pixelratio.html
// create this utils.ts file
import { PixelRatio } from "react-native";
// dp(123) converts 123px (px as in your mockup design) to dp.
export const dp = (px: number) => {
return px / PixelRatio.get();
};
// sp(54) converts 54px (px as in your mockup design) to sp
export const sp = (px: number) => {
return px / (PixelRatio.getFontScale() * PixelRatio.get());
};
Use it like the following way in your styles
const styles = StyleSheet.create({
footerNavText: {
padding: dp(123),
fontSize: sp(54)
}
})
Note
Do not use dp for fontSize. dp just depends on device screen density (dpi)
sp is used for fontSize only. sp is also just like dp but the difference is that it also depends on user's font settings in his device along with the device screen density (dpi).
So i have this code:
var answerView = Ti.UI.createScrollView({ //var added
top: Ti.Platform.displayCaps.platformHeight*0.55,
left:Ti.Platform.displayCaps.platformWidth*0.1,
width: Ti.Platform.displayCaps.platformWidth*0.8,
backgroundImage: '/images/labelBackground.png',
borderRadius: 8,
height: Ti.Platform.displayCaps.platformHeight*0.5,
contentHeight:'auto',
showHorizontalScrollIndicator:true,
scrollType:'vertical',
});
for (var j = 0; j < question.answers.length; j++){
var row = createRow(question.answers[j]);
answerView.add(row);
}
and this function:
function createRow(answer) {
var row = Ti.UI.createView({
width:'100%',
height: 'auto',
});
var answerButton = Ti.UI.createButton({
top: '1%',
left: '1%',
title: answer.answer,
value: answer.order,
width:'98%',
font : {fontSize:'12sp'},
});
row.add(answerButton);
return row;
}
The problem is, the darn thing overlays all the buttons into one... that is, it isn't "pushing down" the rows. From the titanium tutorial here:
http://docs.appcelerator.com/titanium/2.1/index.html#!/api/Titanium.UI.ScrollView
I would have thought this would work, but it doesn't. I know i can do some magic with the numbers and send each row the position it should have, but I thought maybe titanium would be clever enough to do that? Am i missing something?
Oh jesus.
Titanium is moronic in this instance - the problem was I had
height: 'auto' in the definition of each row - that is:
function createRow(answer) {
var row = Ti.UI.createView({
width:'100%',
height: 'auto',
});
...
And funnily enough, that makes each row REALLY BIG, probably as big as the entire space alloted for the row. I don't know, i never tried to scroll through it. So just change the height value for the row to something sane - i always base mine off the display height.
Now I have
function createRow(answer) {
var row = Ti.UI.createView({
width:'100%',
height: Ti.Platform.displayCaps.platformHeight*0.1,
});
...
and all is well.
Okay, guys -- I have to admit that my frustration level is growing as Titanium development continues to kick my backside. Every change I make, however innocuous it may appear, seems to break something else in a completely unexpected way.
Today, I'm simply trying to add a label to a view, but it's not displaying.
// UI Factory Include
var Inova = {};
Ti.include( '_ui.js' );
var win = Ti.UI.currentWindow;
win.layout = 'vertical';
// Header
win.add( Inova.ui.createHeaderView() );
// body
var body = Ti.UI.createView({
backgroundColor:'#00f', // Should see no blue
backgroundImage: '/images/body.png',
height: 350,
layout: 'vertical',
});
var label = Ti.UI.createLabel({
color: '#000',
text: 'Show me the label...please?',
textAlign: 'center',
});
body.add( label );
win.add( body );
I know I have to be missing something incredibly stupid and basic, but I think I've lost all ability to see the obvious. Help?
I think you need to explicitly set the width/height in the label. You can set it to width: 'auto', height: 'auto' but it has to be set.
(Oddly enough this is not true in Andriod, from my experiences).
Whenever I get flummoxed by the API, I return to the basics. Try this:
Create a new project called myTest. In the apps.js file add the following code to the bottom of the file above the last line
var win3 = Titanium.UI.createWindow({
title:'Tab 3',
backgroundColor:'#fff'
});
var tab3 = Titanium.UI.createTab({
icon:'KS_nav_ui.png',
title:'Tab 3',
window:win3
});
var label3 = Titanium.UI.createLabel({
color:'#999',
text:'I am Window 3',
font:{fontSize:20,fontFamily:'Helvetica Neue'},
textAlign:'center',
width:'auto'
});
var txtLabel = Ti.UI.createLabel({
color: '#000',
text: 'Show me the label...please?',
textAlign: 'center',
left: 100,
top: 50
});
win3.add( txtLabel );
win3.add(label3);
Your label, txtLabel, will now appear below label3 on tab3. I tried using the code you provided, but failed to get it to work as well. So, start with a basic page that shows the label, then add the other components until you get the expected results.
Hope that helps.
