Basically, I need a scrollView which is shrinked horizontally. Now, when I insert a bunch of text in it, it doesn't adjust it, text just goes over the edge of the scrollView, like this: http://prntscr.com/ai0100
This is my scrollView code:
local scrollView = widget.newScrollView
{
hideBackground = false,
hideScrollBar = true,
left = 64,
top = 0,
width = contW - 128,
height = contH,
topPadding = 256,
bottomPadding = 20,
horizontalScrollDisabled = true,
verticalScrollDisabled = false,
}
I insert a bunch of text later, and screenshot above is the result. How can I fix this?
Read this: https://docs.coronalabs.com/api/library/display/newText.html
In order to wrap a text you have to set the display.newText() width parameter accordingly.
So something like
scrollView.newText
{
text = "I am a super text"
width = 123 -- replace with your desired width
}
This is another way:
local lotsOfTextObject = display.newText( lotsOfText, display.contentCenterX-40, 0, samewidthasscrollview, 0, native.systemFont, 30)
scrollView:insert( lotsOfTextObject )

I have a vertical UIStackview with 3 controls in it.
I want all the controls to be centered, and the first two to expand the whole width available. The third one should take 80% of the available width and be centered as well.
Here is the result I got so far:
As you can see the third control is left aligned.
Here is the code I have for all of this:
var container = new UIStackView
{
TranslatesAutoresizingMaskIntoConstraints = false,
Axis = UILayoutConstraintAxis.Vertical,
Distribution = UIStackViewDistribution.EqualCentering,
Alignment = UIStackViewAlignment.Fill,
Spacing = 10f
};
// Create the Title
UILabel title = new UILabel
{
TranslatesAutoresizingMaskIntoConstraints = false,
Text = item.name,
TextAlignment = UITextAlignment.Center,
Lines = 2,
};
container.AddArrangedSubview(title);
// Create the gauge
SFCircularGauge circularGauge = new SFCircularGauge { TranslatesAutoresizingMaskIntoConstraints = false };
circularGauge.Tag = circularGauge.GenerateViewTag();
circularGauge.HeightAnchor.ConstraintEqualTo(100f).Active = true;
#if DEBUG
circularGauge.BackgroundColor = UIColor.Cyan;
#endif
container.AddArrangedSubview(circularGauge);
// Add the evaluate button
var evaluate = UIButton.FromType(UIButtonType.RoundedRect);
evaluate.TranslatesAutoresizingMaskIntoConstraints = false;
evaluate.SetTitle(Utilities.GetLocalizedString("qol_rate_button_text"), UIControlState.Normal);
evaluate.SetTitleColor(UIColor.White, UIControlState.Normal);
evaluate.BackgroundColor = new UIColor(red: 1.00f, green: 0.37f, blue: 0.00f, alpha: 1.0f); // Optimistic Orange
evaluate.Layer.CornerRadius = 5f;
evaluate.AutoresizingMask = UIViewAutoresizing.FlexibleWidth;
evaluate.ContentEdgeInsets = new UIEdgeInsets(top: 0, left: 10f, bottom: 0, right: 10f);
evaluate.UserInteractionEnabled = true;
evaluate.TouchUpInside -= Evaluate_TouchUpInside;
evaluate.TouchUpInside += Evaluate_TouchUpInside;
evaluate.Tag = evaluate.GenerateViewTag();
viewIdsAutoEvalsIds.Add((int)evaluate.Tag, item.id);
container.AddArrangedSubview(evaluate);
evaluate.WidthAnchor.ConstraintEqualTo(container.WidthAnchor, 0.8f).Active = true;
evaluate.CenterXAnchor.ConstraintEqualTo(container.CenterXAnchor).Active = true;
I can't figure out where is my problem. In the UIStackView configuration? Somewhere else?
Thanks in advance.
The property Alignment is to sets the alignment of the non-axial subviews . In your case , you need to set it as
UIStackViewAlignment.Center
instead of
UIStackViewAlignment.Fill
This might be a bug of the control. We'll see.
In the meantime, thanks again to the Reveal Tool, the gauge has no width defined.
I solved the problem by setting the width constraint explicitly:
// Fix the width to be 100% of the container
circularGauge.WidthAnchor.ConstraintEqualTo(container.WidthAnchor).Active = true;
I created a block to add UISlider programmatically to have total control of the design. How ever it displays on the thumb image without showing the tract. I will appreciate if anyone could help me resolve the problem.
thank you.
let ageSlider: UISlider = {
let ageS = UISlider(frame:CGRect(x: 10, y: 100, width: 300, height: 20))
ageS.minimumValue = 0
ageS.maximumValue = 60
ageS.value = 24
ageS.tintColor = .green
ageS.isContinuous = true
print("creating age slider")
//ageS.maximumTrackTintColor = UIColor.trackStrokeColor
//ageS.minimumTrackTintColor = UIColor.pulsatingFillColor
ageS.translatesAutoresizingMaskIntoConstraints = false
return ageS
}()
You need to add a width constraint to your slider object:
// add age slider constraints to age view. ageView is the container of the ageSlider
// center ageSlider both horizontally and vertically
ageSlider.centerXAnchor.constraint(equalTo: ageView.centerXAnchor).isActive = true
ageSlider.centerYAnchor.constraint(equalTo: ageView.centerYAnchor).isActive = true
// constrain ageSlider width to 90% of ageView width
ageSlider.widthAnchor.constraint(equalTo: ageView.widthAnchor, multiplier: 0.9).isActive = true
Don't set translatesAutoresizingMaskIntoConstraints to false if you want to manually set the frame of the UI component.
Either set it to true:
ageS.translatesAutoresizingMaskIntoConstraints = true
or just comment that line.
If you want the size to not be static, and change when the phone orientation changes, or when the frame of the superview changes, ..., then use constraints. In your case, you are missing the width constraint.
I have a wibox with vertical layout and two text widgets:
local w = wibox {
width = 300,
height = 80,
ontop = true,
screen = mouse.screen,
}
w:setup {
{
id = 'header',
widget = wibox.widget.textbox
},
{
id = 'body',
widget = wibox.widget.textbox
},
id = 'text',
layout = wibox.layout.flex.vertical,
}
When string in 'body' textbox is short everything is ok, the widgets looks this way:
But if string is long, the size of the wibox is not enough to display it all so part of the string is cut out:
Is it possible to make wibox size change dynamically depending on size of the content?
I'm not quit sure what you want. If you want to adjust the height of the wibox for the content:
After you change the text of the textboxes, run something like the following code:
local t1 = w:get_children_by_id("header")[1]
local t2 = w:get_children_by_id("body")[1]
local h1 = t1:get_height_for_width(w.width, w.screen)
local h2 = t2:get_height_for_width(w.width, w.screen)
w.height = h1 + h2
If you want some extra empty space like in your first screenshot, you could add some number to the height. 42 is always a good answer. ;-)
The best way to describe my situations is with images. What I have is a view which contains several UILabels and UIImage. The red box is a UILabel and if the content is too big it should go to the second line.
From the storyboard I have a working case when the content fits but the problem is that I am not sure how to handle the case when the last (red box) should go to the second line. I am using autolayout and cartography.
If someone can point me to the right direction I will be very grateful.
First calcululate width of text as per your current label's position.
If text width is more than current label's width then see my answer from below link:
Auto Layout how to move the view2 from right to the bottom?
Calculate width:
func widthForView1(_ text:String, font:UIFont, height:CGFloat) -> CGFloat
{
let label:UILabel = UILabel(frame: CGRect(x: 0, y: 0, width: your_label_width, height: your_lable_height))
label.numberOfLines = 0
label.lineBreakMode = NSLineBreakMode.byWordWrapping
label.text = text
label.font = font
label.sizeToFit()
return label.frame.width
}
You cannot do that with constraints only. To change the entire position of the element on the screen, you need to do it programmatically.
Use of tag View can solve this issue. TagListView is an external library.
When u add a view as subclass of taglistView, its height automatically increases accordingly.
ADD this to pod file : pod 'TagListView'
func addTags() {
let str1 = "Hi"
tagListView.addTag(str1)
let str2 = "Helloo"
tagListView.addTag(str2)
let str3 = "How Are u ? "
tagListView.addTag(str2)
tagListView.isUserInteractionEnabled = false
}
I'm trying to create a scrollView where u scroll between different labels. As an illustration i have this image:
I want to make the bottom scrollView i've tried creating a replicate, but in my case it is only adding "Book" to the scrollView and how can i make a smaller spacing between the labels. because in my code there are one label per self.view.frame.width
categoryArray = NSArray(objects: "Book", "Elektronik")
var textWidth = 0
for val in categoryArray!
{
var textLabel: UILabel = UILabel(frame: CGRectMake(0, CGFloat(textWidth), categoryScrollView!.frame.width, categoryScrollView!.frame.height))
textLabel.textAlignment = NSTextAlignment.Center
textLabel.text = val as NSString
categoryScrollView?.addSubview(textLabel)
textWidth = textWidth + Int(textLabel.frame.size.width)
if textWidth > Int(self.view.frame.width) {
categoryScrollView?.contentSize = CGSizeMake(CGFloat(textWidth), categoryScrollView!.frame.height);
}
}
I don't read swift very well, but it looks to me like the code is advancing the y position of the label frame on each iteration, rather than the x. In other words, change:
CGRectMake(0, CGFloat(textWidth), categoryScrollView!.frame.width, categoryScrollView!.frame.height)
to:
CGRectMake(CGFloat(textWidth), 0, categoryScrollView!.frame.width, categoryScrollView!.frame.height))
