Slider with thermometer like scale [message #27646]

Hello all

Is it planned in short term to mark the slider on its side with gradations like a thermometer scale?

If no, do you have any aesthetic ideas about how to do it?

Did you include it in the same Slider ctrl or you would do a new LengthMarkings class.

Best regards
Iñaki

Hi, I have made a lot of improvements to the slider ctrl, including the ability to have a variable number of labels on the side.

Also, multiple thumbs on the same slider, and ctrls that are tied to the slider for output (ie a label ctrl that is updated automatically with the slider value).

I have been planning to submit this for incorporation into Upp, but I haven't had time to do much testing on it yet. Also, I haven't figured out how to add the Upp documentation yet...

I am using it in my own project, it seems to be working fine so far.

I'm relatively new to UPP and will like to learn how to do this. Do you think you could share the relevant parts of how you did this scale?

Thank you in advance for any assistance you may provide

Here are my files for your reference. replace the ones in the ctrllib folder.

If you make any additions, let me know, as possibly we can include them as well.

I still plan to submit this for inclusion to the core asap...

Hello avpavp

Thank you for your improvements Smile

.

Some questions and comments:

- With SetTextLabels(int n) we can set the number of labels. How it is possible to paint the length markings or gradations?.

- Now the thumb goes under the labels. It seems to be more natural that the thumb is over the labels

I changed it so the thumbs are on top and added the gradations

SetGradations( int n );

You may need to size the slider in the layout manager to make the text etc fit best.

Hello avpavp

Thank you very much for your fast response!

I would like to comment you some additional details Smile

Smile

:

- Now it is not possible to use GetData() because it is ambiguous. If you use GetData() the compiler does not know which of both to use:

 	virtual Value GetData(int nIndex = 0) const;
	virtual Value GetData() const;

- Gradations are there, but they are not very visible. Would it be possible to increase its length and/or width?

index.php?t=getfile&id=2690&private=0

index.php?t=getfile&id=2690&private=0

- Screenshot above has these lines:

		slider.SetTextLabels(5);
		slider.SetGradations(3);

It seems more natural to have the same number of gradations and labels.

Thank you again Smile

Hi,

I disagree a bit with API. What about having...

SetTickNum(int n); // SetTickCount
TickHaveLabel(bool b = true); // TickHaveNum , TickHaveText, HaveTickText, etc.

or something similar.

Thanks for your feedback.

I'll add some customization to the gradients over the next day or two. Probably I will add some ability for major and minor ticks (different sizes).

I think the ticks and labels should be independent. Commonly (I think) you might want more ticks than labels.

Anything else I should consider or other ideas while I'm working on this?

Thanks,
Anthony

Have the labels determined by a Convert instance (or StdConvert by default). It'll be simpler but more flexible interface.

The Paint code could use a little improvement too. The labels are too close to the 'track' IMO and the tick could also extend slightly further upwards.

Here's my latest SliderCtrl.

I changed the way most of the labels and ticks were handled. Now things are based on Major and Minor ticks.

Major ticks have text labels. If you had a slider going from say, 0 - 200, you might set MajorTicks to 25, which would put larger ticks and text labels at 0, 25, 50, 75 ... 200.

Then you might set MinorTicks to 5, which would put minor ticks (smaller, no text) at 5, 10, 15, 20, 30, 35, ...

Also, you can set the tick sizes for Major and minor, 0 to 100 % of the size of the ctrl from the slider line to the edge.

Finally, you can set the tick location to above/below the line (left and right too).

I'd like to submit this for inclusion in the core once all the kinks are worked out. I gather I should generate the topic++ files or something? I looked around as much as I could, and couldn't really figure out how to do this. If Ultimate++ wants tpp or t++ or topic++ files I humbly suggest you make it a little better known how to create such files...

Thanks,
Anthony

Hi Anthony

This looks very good. Couple of things that you might like to look into

1. There is a skew between the ticks and the thumb position. Like if the slider.Range is 100, the thumb almost always is left aligned to the tick when on the left of the median and right aligned as you go to the right of the median.

2. I could not get the slider.SetTickPosition to work. Keeps throwing up an error. Maybe I am doing something wrong due to inexperience in UPP
This is the relevant code cut from the sliderprogress package modified to use the new slider control

	App() {
		Add(slider.BottomPosZ(5, 50).HSizePos(10, 10));
		Add(progress.VSizePos(10, 50).HCenterPos(50));
		Add(text.LeftPos(5, 200).TopPos(5, 40));
		slider <<= THISBACK(Slider);
		slider.Range(100);
		slider <<= 5;
		slider.SetMajorTicks(10);
		slider.SetMinorTicks(1);
		slider.SetMinorTicksSize(40);
		slider.SetMajorTicksSize(50);
		//slider.SetTickPosition(BOTTOM);
		Slider();
		Sizeable().Zoomable();
	}

Would it be possible to autosize the Major and Minor ticks as a % of the slider size? A USC file to help set the slider in layout will be great help.

Thank you very much for your help with this.

I've spent quite some time looking at the alignment issue. I think there were a lot of issues with the drawing placement in the original SliderCtrl code, but no one could notice because there were no ticks or numbers Wink

Wink

Anyway, I have fixed this up significantly, and cleaned up more of the SliderCtrl code in general.

You need to use:

slider.SetTickPosition( SliderCtrl::BOTTOM );

AutoSize would be nice.

Can you point me to some information on USC files? What do I need to do?

Hi Anthony

Thank you for your updates. I'll check it out tomorrow, its almost midnight here and I'm too excited to bother with sleep. See my thread on the serial port.

I'm a newer newbie than you Laughing

Laughing

Anyway, pick any control you like and look at the usc code in its package. I think it is also documented in the Help file.

I was able to do some quick mods to make my own meter class out of the Controls4U meter, slider and textbox. What I did, was to pick the USC code of the meter and modify it in my own MyMeter.USC file.

If you have any issues, let me know, I'll try to help. This forum is really great and I've learned a lot since my first post.

I've been silently working on adding to the work done by Anthony. I have not been able to do much, but, this is my contribution.

It is now a Slider with fill and has the vertical slider having its min on the bottom of the screen - like a vertical progress bar.

I'd like to have a class member to change the fill color eventually.

I have made a better fill slider and slide switch which I have attached here. However, I have hit on obstacles in tying the USC code to my class. I wonder if there is any more documentation on how USC handles things. For instance, I found the enum_property keyword that makes an enumeration of property values. I'd like to use that to define the behaviour of my Fillslider and slidesw

Right now, I have done something like that in the USC code, but it fails if I change from the default value of CONTROL to INDICATOR

These are the 2 new slider controls. Comments / peer review appreciated

Hi Koldo

I have done as you suggested. There are some places where I need to improve -

1 - how to set CONTROL or INDICATOR from USC code.
2 - in SlideSw, I am unable to set the value on the slidesw indicator when clicking on the slidesw control away from the thumb. If I click and move the thumb the indicator updates correctly.
3 - how to set the vector of Names from either USC or code. Right now, I am doing it right inside the control which is not desirable.

The controls in the file are JFSlider, SlideSw, JFStaticText and MyMeter. The last one of course is specific to my requirement, but, I let it remain in the group. Later I can plan to gather all the USC code into 1 file. Is there any more details on ESC script than what is in the documentation; it seems quite lacking in detail. Things like enum_property, >Ctrl, Frame frame @1; do not make sense at all and do not seem to appear in the docs.

Thanks for your help

Hello Jerson

Here I enclose you the modified code. Check the differences with original. Some advices:

- I would include all slider classes in one. Both are almost the same, but some of the problems in .usc came from the names where very similar, but not right.

- You created Callback WhenSlideFinish but in main program you do <<= THISBACK(), so you assigned the callback function to WhenAction, so nothing happened when thumb was moved.

Hi Koldo

Thanks for your immense help. Because of your active help I am almost swimming in UPP Smile

Smile

) I am now hooked to UPP.

I can now navigate the files effortlessly even though I stumble occasionally. Like I mentioned in my previous post, I plan to consolidate all the USC code for my controls into 1 grand file.

Can you enlighten me on Point 3 of my previous post. What I want to do is do a vector.clear operation and populate the vector either from the Main.cpp or from USC code (better option) so that I can visualize it correctly in the designer.

Any more rough drafts of the ESC documentation wherein more details can be obtained? I feel the ESC documentation is incomplete or maybe I am not looking correctly.

I am now so excited, I might contribute some more controls as I progress in UPP.

I do not know how to do it in .usc the easy way.

The less easy way could be to do a function like SetLabels("0;Begin;25;Medium;50;Top"). This works and you will visualize the result in layout designer.

Quote:

You are right.

This is great from you Smile

This is my contribution.

In this package you will find
- the slider control and indicator
- slide switch control and indicator
- a Text label which can have its own background color
- mymeter which is just some embellishment of meter
and JFControlsDemo to check it all together

It is a little fancier and may not be generally suited for all, but, for my instrumentation needs, it is just fine. The tpp may be out of sync as I strung it up in a hurry.

A detail. could it be possible to separate the labels from the marks?

index.php?t=getfile&id=2846&private=0

index.php?t=getfile&id=2846&private=0

Jerson, as I think your control is more different from classical Slider than avpavp version, could you propose improvements to have a joined and better SliderCtrl?.

If you increase the vertical height of the slider, the labels will move from the ticks. Is that what you mean? Or what do you propose?

Hello Avpavp

I see. Could you include this feature in any way in the layout editor (.usc)?. Also the lower side of the slider (without marks) remains empty. Perhaps it is a better behavior that the slider would fill its Rect. The only thing is that this way the slider line would not be centered. I mean (now and proposed):

:

- Now the labels are printed using AsString(). Could it be possible to set a user defined formatting function?

Imagine this case. The slider uses seconds and there are a major tick every minute. I would prefer to put "1" instead of "60" and so on:

- In addition, when it is clicked outside the thumb, it is called to Inc() or Dec(). Would it be possible instead, to move the thumb to the position that has been clicked?. This means the user wants to go to that position (imagine your are using VLC Smile

- Click outside the thumb, there is a fn Jump(), call Jump( true ) to get the behaviour you are requesting.

- user defined formatting fn, this sounds like a great idea. So it would be a virtual fn I guess? Or is there a better way?

- I don't know much about .usc files, but I will try, can you point me to some information?

- Your idea to better use the space is a good one. I will look into this as well.

I prefer a Callback, because:
- If it is used a virtual function
-- You need to create a derived new class
--- So in the layout designer you get an empty box instead of a nice widget Sad

To see an example, go to Scatter package, cbModifFormatX.

For example:

graph.LabelFormat = THISBACK(MyFormatFunction);
...
void MyClass::MyFormatFunction(String &s, int val) {
	int min  = int(val/60);
	int secs = val - 60*min;
	s = Format("%02d:%02d", min, sec);
}

I would remove before the slider spacing. After that I would go to .usc, as usc will copy original C++ code as much as possible.
