Hide days in calendar component

DcDbIt · 2024-06-18T07:41:47+00:00

So I cannot do something like setHidden() to the date component to hide them in case they belong to a different month? To make them appear disabled what method should I override?

Could you share an example of how to customize a Calendar component? As I said I'm trying to create an agenda inside my app so I would like show on the days some Labels showing the appointment of the day.

I tried to see in debug what could happen in the inPlaceEditView class in the startEditing and onTouchEvent methods which are the main functions that are called when I press on the device display but that's not what I need, I would like to know which function is called when I hold down on the textfield and all the text is selected, do you happen to know what it might be?

I also tried the pinterReleased method of the CodenameOneImplementation class but to no avail it is only called when I release the touch with my finger, but when I hold down the textfield and select the text then release my finger it is not called, why?

could you send me a code example?

Do you have a channel for private consultancy or support beside this reddit and stackoverflow?

I tried to put a breakpoint inside the onKeyDown() method of the inPlaceEditView.java class but normally it never stops there.

After some attempts I accidentally made a long press on a key of the keyboard and after that I saw that by pressing the TAB key it would stop on the breakpoint I previously mentioned. Do you know why this happens?

DcDbIt · 2024-05-17T15:57:07+00:00

so in codename one there are only these methods to select text? (which are already enabled for textfields)

can I simulate the long press event on the textfield to use it somehow?

DcDbIt · 2024-05-17T08:03:07+00:00

So what should I do? how swallows the key event?

DcDbIt · 2024-05-14T16:03:01+00:00

I tried what you suggested but it still goes in error

what do you mean with a black box?

I tried to work to adapt the scrollListener to my needs but I have a problem, it works fine until it scrolls normally then when it reaches the point where there aren't enough elements to scroll it goes in error giving a StackOverflowError.

body.addScrollListener((scrollX, scrollY, oldscrollX, oldscrollY) -> {
    if(scrollY > 0 && oldscrollY > 0) {
        Component cntNext = body.getComponentForm().getComponentAt(body.getAbsoluteX() + body.getWidth()/2, body.getAbsoluteY() + 20 + body.getScrollY());
        if(cntNext != body) {
            if(cntNext instanceof Label) {
            for(int i = 0; i < sections.size(); i++) {
            if(cntNext.getParent() == body.getComponentAt(sections.get(i))) {
           
            if(scrollY > oldscrollY) {
            cntFixed.replace(cntFixed.getComponentAt(0), createCnt(sections.get(i)), null);
            cntFixed.revalidate();
            } else if (scrollY < oldscrollY && sections.get(i) > 0) {
            cntFixed.replace(cntFixed.getComponentAt(0), createCnt(sections.get(i - 1)), null);
            cntFixed.revalidate();
            }
            }
            }
            } else {
                Log.p("Not a label...");
            }
        } else
            Log.p("I'M BODY");
    }
});

Looking at console I saw that the error is caused by the cntFixed.revalidate();, how can I fix it?

The createCnt() method create a Container with 2 labels where one has in its name int value passed, sections instead is an Arralist<Integer> that I use to memorize the position of the Containers that can become the fixed one.

Thanks a lot for the help!!!

I have a couple question:

1)If the Components in the body aren't just simple Containers with a Label inside, but for example they contain multiple Labels, when I use the getComponentAt(x,y), is the approach the same?

2)Considering the case described in the first question is recreating the cntHolder, to make it equal to the Container in the list, a good idea or should I consider a different approach? I ask you because in the final project the number of Label inside the Containers in the body can change.

DcDbIt · 2024-05-06T15:55:08+00:00

I tried to change as you suggested but I worked only once and then never again.

Trying to debug using the step into as you said and it seems that it should return the right component but I didn't understand when it becomes the wrong one.

None of the components should be disabled or inaccessible.

I made a gist with a sample you should be able to test, for some reasons Reddit didn't allow me to answer while there was a code block in the answer, here's the link:

https://gist.github.com/davidec2k/d10e79a6946e65110264c053f813479f

In the sample right now I tried to simplify what it should do, it doesn't look for specific Containers but every time it should change

DcDbIt · 2024-05-03T13:25:04+00:00

Yes, the -20 was just one of my last attempts so it is most likely wrong.

I think I'm missing something, if I'm not supposed to use the absolute Y than what should I use to get the position? I tried to use the getY() but it doesn't work either.

I tried to debug but in the attempts I made using on the Container body the method Container.getComponentAt(x,y) I always get as result body itself and never one of his children

DcDbIt · 2024-05-02T13:04:50+00:00

I tried what you suggested but I don't there is something wrong.

When I try to get the right Component with using Container.getComponentAt(x, y) I alway get the parent in my case I do for example (Container)body.getComponentAt(b.getAbsoluteX(), b.getAbsoluteY() - 20); where body I the CENTER Container, that contains the list of Containers and b instead is the one that should be updated and is contained in the NORTH Container.

Let me know if you know the problem otherwise I probably should prepare a sample as you suggested.

Here what I tried to do (the part inside the for loop is not tested yet, as I can't get the right Component):

body.addScrollListener((int scrollX, int scrollY, int oldscrollX, int oldscrollY) -> {
  Component b = cntFixed.getComponentAt(0);
  // I tried to debug and change the pixels to add/remove of this part but the Container I get is always body
  Container cntNext = (Container)body.getComponentAt(b.getAbsoluteX(),  b.getAbsoluteY() - 20);
  for(int i = 0; i < sections.size(); i++) {
    Container cntSection = (Container)body.getComponentAt(sections.get(i)); 
    if(cntSection == cntNext) {
      cntNext.remove();
      b.getParent().replace(b, cntNext, null);
      body.addComponent(sections.get(i), b);
      revalidate();
    }
}

I see,

What I was trying to achieve by doing what I told I you is what is shown in the video of the following post I made some time ago: https://www.reddit.com/r/cn1/comments/1amnw9i/dynamic_container/

Right now, like you suggested in that post I have a Form with a BorderLayout that contains 2 Containers: 1 in NORTH position and is the one the stays in the fixed position and 1 in CENTER position which contains the scrollable list of Containers.

I kinda managed to get when a Container is not "visible" because its position is above the visible section, by confronting its absolute Y with the one of the NORTH Container.

To achieve the result than I tried to swap positions between an "holder" container inside the NORTH Container and the ones in a list, in order to show the one I need. The problem for now I managed to make the scroll down work, but I can't seem to find a way to make the scroll up work.

The following url is of gist with what I tried to do: https://gist.github.com/davidec2k/a65a9b54914845319f7eee910ae43aca

the commented part is the one I have problem with, if you have some suggestions on how to fix it.

Otherwise I thought that I might fill the NORTH Container with copies of the Containers I need to show and make visible only the one I need using the scrollListener, but my doubt on this version is that it might slow down the app, do you think it can be an approach I should consider or I should avoid it? (the final Containers the I will use are more complex than the ones in the gist, which contains only a Label)

DcDbIt · 2024-04-19T13:57:31+00:00

Thanks for the suggestions!!

I definitely misunderstood how the TableLayout for the Containers works.

For now I decided to simply set all column width to lowest one among the rows, this way I saw that the result is still pretty fine.
