I'm currently working on an assignment for my web development course. The premise is to create a simple "concert ordering site". Everything is well, but I keep running into this error message:...
ANSWERAnswered 2020-Oct-21 at 20:22
You don't have a form control with a
name="chooseTheAmountOfTickets" value. I'm assuming that's what this was meant to be:
There's a great Xamarin.Forms sample project titled Empirical Font Size that calculates the maximum possible font size for a
Label within its containing view. It takes the label in question, uses
VisualElement.Measure() to get some size requests for the label based on its properties, and compares the requested sizes to the container's size to see if the label will fit with that font size. It recalculates until it finds the best fit. It works great, but I want to modify it to do more.
Unfortunately, I've hit some nasty roadblocks in my modifications, and I'm not sure if they're more C# or Xamarin related. Here's what I'd like to do.
- Extract the calculations into their own function for use anywhere. -> The original doesn't do this. This bit's actually already done, but the following goals aren't working so it's good to bring this up as the starting point.
- (FOCUS HERE) Avoid using the original label data in the function. (Make a copy.) -> I'm adding some features that require me to actively change the label text data during sizing calculations, but modifying the label I'm sizing can cause issues (not always with the sizing, but in other ways). I need a way to duplicate the label for font sizing in order to protect the original data. (More on what I've tried below).
- Abstract the function to allow sizing of other views. -> Right now, this only calculates max label font sizes. If possible, I'd like to support auto font sizing for other views like picker, entry, etc. Food for thought while figuring out #2.
Goal #2 is where I'm having problems. I can't find a way to duplicate a label and then perform sizing calculations on the temporary copy. Here's what I've tried and how each attempt has failed.
- Make a shallow copy. (e.g.
Label copyLabel = origLabel;) -> As expected, this doesn't work because the new label copy is still referencing the same original label data in memory. So if I set
copyLabel.Text = "hello", then
origLabel.Textwill also change to "hello". Not good.
- JSON copy -> I've seen recommendations to use JSON converters to serialize and then deserialize a View in order to do a quick deep copy, but I got an exception when I tried this. Something about a
self-referencing loopon the label's children.(Do labels even have children??)
- ICloneable -> I'll be running this function in a static class, so I can't do this. It might not matter because of the next attempt, though.
- Make a new Label object and copy some values. -> This almost seems to work, but the catch here is the
VisualElement.Measure()calculation. The new label is missing something required for the calculation to work properly, and I don't know what that is.
For any of these to work, I'd need to copy the label, immediately perform calculations on the copy, and apply the resulting font size to the original. Then the copy disappears. Poof! Unfortunately, any copy I make results in different calculations, so this is where I'm currently stuck.
Someone mentioned elsewhere that maybe the sizing doesn't work because the new label isn't part of a layout and thus can't be sized, but they didn't explain so I don't understand what they were getting at.
To see what works and what doesn't, here's a small Xamarin sample project with a modified version of the Empirical Font Size project. It's a simple A/B test. Two labels with the same text are sized by two near identical functions - one that uses the original label and one that tries to use a copy. They should fill the top and bottom halves of the provided stack layout, but the copy doesn't work. I'd like help making that work.

I figured out a safe, simple workaround for this issue that I call 'ghost sizing'. You can create an invisible 'ghost label' and place it into a page where a label will be sized. It's not visible, so it doesn't change the layout at all, but it is still usable in size calculations. You pass the text of the label you want to size into the ghost label, size the ghost label to the desired space, and apply the returned size value to the target label.

You have a selector

I don't understand why I can add Inheritance m_tempSensor(id) with id argument when TemperatureSensorIF constructor not expect any argument, and why as argument I give pointer to "TemperatureSensorIF."

There is something like that:...
ANSWERAnswered 2020-Apr-30 at 06:54
: m_tempSensor(id) you initialize the inherited member variable, which is different from calling the parents constructor. In your case the parent class constructor is called automatically because it has no parameters, which is equivalent to:
So currently I have an app that looks great on my device, what I see but on another device It looked like this. Both devices are android and I have used the preset FontSize's (micro, small, default, large).
I have used a variation of this but I cannot get it to work corrently, It comes out like this. I actually find that if I divide the result by 2 it actually gives a decent result but I want to make sure I am not doing anything fundamentally wrong or if there is a much simpler way!

Probably because this was the case in 2017 and it's not anymore.
The question you're referencing are from 2016 and 2017.
Since then you'll always see

and my focus now on how to implement deque?
Edite: from comments below I get useful directions on how to implement
deque based array. Is there a direction how to implement
deque based objectusing class ?
I get understand some points like I need :
but I'm confused about some points :
how many pointers I need ? at least I know from queue I need two(head-tail) pointer but not sure if I need more in deque
in chapter5 of this book the author started to implement Deque based on object only and some variables
but I didn't understand how he did that because the code encrypted but I can still reach to his files from and test his approach github repository
I can say that @trincot answer very close of book author approach
according to the book index taking about linked list comes in chapter6 so I didn't expect his solution will be based on something he didn't mentioned before
plz if I miss any point I will be grateful to tell me it ... thanks...

You can use Chapter05 like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the Chapter05 component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
