Option to set "scrollbar thumb" and "micromap current view area" minimum size

[pintassilgo]

I realized scrollbar is very hard to see in long documents because thumb color is not that different from background color as it should be: Can you see the thumb? It's much harder than it should be.

So I tried changing colors for scrollbar items in Settings - theme - ui, but most of them did't work, Then I tried disabling micromap_on_scrollbar and voilà, scrollbar is colored with the colors I chose.

I was already writing a new issue when I realized I must look at micromap, BG and micromap, current view area in Color theme dialog. So micromap replaces scrollbar entirely when you use micromap_on_scrollbar = true, OK.

But one suggestion remains: add an option to set mininum scrollbar thumb height. As you can see in the image above, for long documents the thumb can be very small to the point of being hard to see and to reach it with the mouse. For instance, my OS-painted scrollbar has much bigger minimum height if I turn off scrollbar_themed (KDE Plasma is my DE).

I use micromap on scrollbar, so this proposed new option should also apply to micromap thumb (aka "current view area"). Or, if you don't want to mix these two, I suggest one option for each.

Extra question: what's the purpose of scrollbar, scrolling area in Color theme dialog? While I was testing, I changed it to black just to see where it affects, but I see no black in scrollbar (did this test while micromap on scrollbar was disabled, of course).

to see it: click and HOLD mouse down below the thumb. to activate page-down scrolling by timer. do you see?

pale green here.

Seems I can do the request. atscrollbar.pas -

    MinSizeToShowThumb:= 10;
    ThumbMinSize:= 8;
    ThumbMarkerOffset:= 3;
    ThumbMarkerMinimalSize:= 20;
    ThumbMarkerDecorSize:= 2;
    ThumbMarkerDecorSpace:= 2;
    ThumbMarkerDecorDouble:= false;

now I must find what here is the needed var..

[pintassilgo]

No, maybe because I use "scrollbar_click_jump": true,.

[Alexey-T]

So you cannot see that color.

[pintassilgo]

Still talking about scrollbar. Is there any reason for the micromap marks not to be centered on scrollbar? It would look better. Currently it's more to the left.

[Alexey-T]

yes we have a reason. API allows placing more micromap marks on new columns. also AFAIR(!) the spell checker marks are on different column (not sure)

[pintassilgo]

OK, I just tested disabling scrollbar_click_jump then I saw the color.

[pintassilgo]

Is there any way to test?

As you can see, I typed a true word far to the right, but all marks are still aligned to the left, without a single mark to the right as I expected after reading what you said.

[pintassilgo]

Still exploring this subject, is there a way to set a different color for the mark related to the selected word (under caret)?

[Alexey-T]

It wont work so, marks are always on the left. AFAIR the plugin 'Spell checker' marks are on the right

here are pics from the Wiki. I don't remember how to show marks on the right..

micromap on bar:

mark on the left- 'line states'. in the middle- 'occurs'.

[Alexey-T]

yes. maybe it's the 'selection color'? make the selection with 20 lines. you will see selection marks on the RIGHT of micromap

lite blue here.

[Alexey-T]

You must read - https://wiki.freepascal.org/CudaText#Micromap

[pintassilgo]

OK, I can see line states on the left and selected word on the right. But there are probably two middles, because highlight marks are on "middle-left". Middle-right should be the spellcheck you said, but I don't have this plugin (so if there are only three possible columns - because I don't have spellcheck plugin -, maybe micromap should process 3 cols instead of 4; or maybe the one in the middle should fill both 2 and 3 to be centered).

[pintassilgo]

yes. maybe it's the 'selection color'?

Partially. It doesn't work for HiOccur (word undeer caret, not selection). Suggestion of enhancement for HiOccur. The plugin already has theme_item_current option, but this one is for the highlight the word, not the micromap mark as I'm asking.

You arre suggesting only 3 columns. now there are 4 columns. column 3th is always empty for me. I dont remember why I added column 3th.

when micromap is not on the scrollbar, it has 3 columns as you want.

[Alexey-T]

Change made:

• change: minimal height of micromap's thumb area was increased: 4->12

I don't want the option here, too many options....

[Alexey-T]

(and the same change - for the scrollbar's thumb: 8->12)

[pintassilgo]

Could you please provide a new beta for me to see the new size?

[Alexey-T]

Beta updated , same folder.

[pintassilgo]

It's better now, thanks. Maybe it should still be bigger. Comparison.

New minimum Cuda scrollbar size - 12px:

Minimum Firefox scrollbar size - 34px:

Minimum KDE Plasma scrollbar size - 28px:

So it's still less than half of these.

[Alexey-T]

Okay, changed to 16. I don't want the option here..

[Alexey-T]

Idea - why micromap-on-scrollbar has 4 cols. IMO it is 3 columns! but code has the limit for each col width. this limit is from 'width of char text cell'. 50% of text cell.

OK, thanks.

Can I create an issue suggesting to make HighOccur be able to highlight word under caret?

[pintassilgo]

Idea - why micromap-on-scrollbar has 4 cols. IMO it is 3 columns! but code has the limit for each col width. this limit is from 'width of char text cell'. 50% of text cell.

From what I see it's clear:

• 1st column has 1/4 scrollbar width
• 2nd col has 1/4 scrollbar width
• 3rd col doesn't exist but fills its space
• 4th col has 1/4 scrollbar width

So if you say micromap has only 3 col, 3rd col shouldn't exist and each one should have 1/3 scrollbar width.

[Alexey-T]

HiOccur has the option for this-- 'options / settings-plugins'. opt is called 'caret_allow'.

[pintassilgo]

I use this option, this is not what I'm asking.

I'm saying about the occurrence under the caret to have different mark color compared to the other occurrences in micromap.

[pintassilgo]

Let's say there are 3 occurrences of the word 'null' in the file, in lines 5, 20 and 40.

If i click the word in line 20, I want micromap to display 3 marks, with the one in the middle having a different color from the other two, because it's the one under the caret.

For findbar we already have this using 4th column.

[pintassilgo]

Findbar. If you look carefully to scrollbar, you'll see a light blue at the right of the match in the middle. That's because the word in line 20 is selected after I pressed F3. I propose something similar for HiOccur, so that I can see from scrollbar where is the word under the caret (without having to select it).

[Alexey-T]

So if you say micromap has only 3 col, 3rd col shouldn't exist and each one should have 1/3 scrollbar width.

Made this better, now almost 1/3 of bar width:

why almost? maybe 1-2 pixels are lost, border of map.

[Alexey-T]

Ok, make the HiOccur issue - but I don't think it is useful, so try to give the pull-request.

[Alexey-T]

Is this solved now?

I found why micromap columns are not 1/3 width. position of columns are precalculated! for the normal micromap. and then are resused even when map is on the scroolbar.

maybe later I will correct this.
