Lines that can be redefined

Postby dpayer » Tue May 28, 2013 3:00 pm

I can think of many uses for a line that can be redrawn based on coordinates. Currently we can get the LEFT/TOP/HEIGHT of a line and we can move that line as originally defined to a new location. We can also change the color, width, height and arrow attributes.

It would be very useful to have new capabilities to set the starting point and ending point location (defined in pixels from the 0,0 upper left point of the app) as well.

With this type of functionality, we could use lines for: bar graphs, progress bars, vumeters, analog clock hands, versatile indictators and more.

I thought of this as I was doing an exercise to create a rotating dial using only NB objects. I wanted to use a line as an arrow to point to the values and redraw the line around an axis as the mouse moved but it is currently not possible with NB line objects in their current form.

Example of proposed usage:

setLINEobject "Line1" "X1,Y1" "X2,Y2"

If you suddenly need to watch NB look at this plugin.

David P:

I am not sure what you are asking here.

If you want to be able to "create Line objects at run time via script" ... yes, the ability to "create all objects at run time" has been a long standing request of mine.

But if by "redefined" (as in your topic title), you mean ... just reposition and resize it in a single NeoBook command ... this could be achieved by defining a Function that you Call ... the function could do the necessary calculations for SIzeObject ... and then invoke the MoveObject and SizeObject commands ... the style, color and thickness of the line can be requested in the same Call ... am i missing something ?

I think he means not to move, and rotate the object.

Gaev, I don't want to create something at runtime. I understand that limit.

Try to create a line in NB. Then have that line remain the same length and have it change its direction based on a function. You can make the line "wider" but it will not retain the same length.

Here is a sample app: (create new blank 800x600 app - copy / paste this code into it)
It allows you to adjust all available settings for a line's dimensions. Left, Width, Top, Height

I think I see a possible workaround for this. It involves doing a trigonometric function for each move but there appears to be some odd fluxuation of 'direction' (as indicated by arrow point) when moves are made. Also transitioning from one "quadrant" of change to another will involve some significant trig operations to retain same length of line with one point remaining constant.

Change of 'height' can change directionality, as can width. At certain points, the line appears to 'flip' as one of the values is incremented.

Thank you for the information. I downloaded and installed this plugin on my system (win7) but the demo app doesn't seem to run properly.

I tried to get the caption of the button to do a translation to see what it is supposed to do and the characters I see inside of NB for the top button is not the same as displays on the button and the one I can get does not translate via Google. I am sure it is a character code issue but I don't know how to address it.

I apologize. I did not see that the image files are laid below the post.

download files and put in a folder with the project.

I have a HP and plug-in works.
With the mark of the characters in the seven problem. Try to change the font properties for the button mark symbols. There, the idea is Cyrillic.
The top button Create. Lower the Disconnect button.

I worked over creation of a similar plug-in and already there are certain results, but unfortunately I have not enough time to finish work.
In the future I will try to finish a plug-in, and can Dave will add these additional possibilities in following version NB.

Example on the basis of a plug-in:

Very nice sample !
Are there any way to set the background color for transparency ?

Thanks in advance,

Directly to make a transparent background it will not turn out, only if in advance to copy area under rectangle and to insert into the image with a dial.

Another question:

I need put 4 clocks into a program.
Each clock has different time zone (Buenos Aires, New York, London & Moscow)
Are there any way to set the time for each clock manually ?

Thanks in advance,

Unfortunately such possibility in a plug-in is not provided.

If you like can take a look at my npHour plugin, which allows you to set the time for any of the created clocks. So you can create a couple of clocks and active a Timer just like:

Code: Select all
npHourCreate "ClockOneRect" "[Result]"
npHourCreate "ClockTwoRect" "[Result]"
TimerStart "ClocksTimer" "1000"


And in the Timer event write this other code in order to update the clocks, the first, with the current time, the second with the current time plus two hours:

Code: Select all
npHourSetTime "ClockOneRect" "[Hour]" "[Minute]" "[Second]" "[Result]"
npHourSetTime "ClockTwoRect" "[Hour] + 2" "[Minute]" "[Second]" "[Result]"


Hope this can be useful. ;)
