When i set a Button (NSButton) to be disabled, its text color changes to gray.
How can i modify this property? I want the text to stay black.
To answer your Title if not the body of the question: it's practically an industry standard to represent disabled screen elements this way, and probably what users expect.
To do something different might be confusing.
try setTitleColor:forState:, and pass UIControlStateDisabled for the last argument.

What I want to accomplish:
I need a checkbox with a title text that dynamically wraps and breaks on multiple lines depending on a dynamic width established by the parent view. I need a solution that I can use in IB and that will display there as it's shown at runtime. I'm using XCode 13.1, working in a XIB-File targetting MacOS.
What I'm doing:
I create an NSButton in IB. In the attributes inspector I set its style to Check, under "Control" I choose Word Wrap for "Line Break" and finally I set a very long text as the title such as Asd Asd Asd lit tle words and many of them asd asd lit tle ones.
What's happening:
When setting up the button as described above (case 1) and shrinking its width, it will be displayed - in IB and at runtime - like this:
When manually adding a line break to the title as suggested in this similar question by pressing Option + Enter (case 2, here after "them") the title starts wrapping correctly and all the other necessary breaks are generated:
However this solution is not applicable for my case since it only works for a static width, but my checkboxes need to adjust their width dynamically as described above.
Without that additional manual line break it's most interesting that apparently the checkbox is already reacting and changing its position according to the new wrapped height of the title while the title text itself is just clipped by the bounds of the control instead of being displayed in a wrapped fashion.
What I'd expect:
I'd expect the title to wrap in case 1. Since it doesn't: Is this a bug or a feature? How can I make case 1 work and get the title to wrap dynamically depending on its length and the width of the button? Do I just need to set another attribute in the inspector I missed so far? Or is there only a programmatic solution?
To answer the question why I don't use an appropriately short label: Don't ask me, I'm just a developer following specs & reqs and unfortunately I don't have a saying on what would be a good length of text here.
The credits for this answer goes to #Willeke's comment: "AppKit doesn't support multiline checkboxes." The interesting behaviour of the checkbox in case 1 suggesting otherwise seems to be just a glitch or bug.
What I ended up with: I opted for a workaround. I'm placing a checkbox-button (with Image Position "Image only" in IB) right beside a multiline-label, putting both in a custom view, adding the necessary constraints. With a few positioning adjustments I know have a solution that looks exactly like a singleline checkbox, that I can copy-paste in IB and that is solved by Autolayout - in IB and at runtime - without any additional code.
If I make button relatively small, it's caption turns to ellipsis.
How to turn off this feature?
Don't let the button go below it's preferred size, then it will never need to elide the text of the button label:
button.setMinSize(Button.USE_PREF_SIZE, Button.USE_PREF_SIZE);
I want to make very small button
You can use any of the below either separately or in combination:
Apply CSS to use a very small font in the button.
Make the label text for the button very short.
Use brian's answer which proposes explicitly setting the ellipse string to empty.
Use a small graphic icon instead of text.
You can use setMinSize as documented above in all cases (if you wish the button not to go below a preferred size truncating or eliding content).
In all cases, if you wish, you can also apply CSS to minimize the padding between the label and button the border.
From your previous comment (I want to use simple captions like "<" and ">"), I think option 2 (Make the label text for the button very short) is what you want.
You may also be interested in Joel's Designing for People Who Have Better Things To Do With Their Lives which would indicate, usability-wise that very small buttons are usually a pretty bad idea.
in your label/button you can use the textOverrun property to turn off ellipsis.
textOverrun.set(OverrunStyle.CLIP);
this is probably a bit late for you, so i am putting it here for lone wanderers digging up this question.
It puts ... because there's no room for the text. You can use bigger buttons or a smaller font but if you really want the dots gone use button.setEllipsisString(""); , but then you just get truncated text.
I have a box that I want to take a password of only numbers (like an ATM-card PIN), how is the best way to do that?
Requirements:
Password (with the hidden numbers)
Typing digits as the default (only?) keyboard
What I've tried:
I thought that InputScopes would be the way to go, but I can't set the input scope on a password box. I even tried putting the password InputScope on a normal TextBox, but that didn't mask the appearance of the characters in the text box. Suggestions?
Short version - you don't out-of-the-box as far as I know.
You're absolutely right that PasswordBox don't support InputScope. I would have thought that it inherited from TextBox or a common ancestor for textual input to get InputScope, but it inherits directly from Control. And since it is a sealed class you cannot inherit it and change it behaviour either. I don't think you can achieve it using ControlTemplate either.
So your best bet will probably be to create your own control mimicking the behaviour of PasswordBox, including the second long delay before the shown character becomes the hidden character.
I feel kind of silly asking this question as it seems really simple, but how do I create a text box that I can type in instructions and stuff like that. I don't need the user to be able to change it, it is just to give instructions. I tried the label, but it only allows one line. I need something that can allow about a paragraph or so. Similar to the box in an installer that describes what the program does. What did I miss?
You can use a label but set its AutoSize property to false. This allows you to size the label as you wish and it will automatically wrap the text to fit.
You can also anchor the label to the parent form to have it automatically resize and reflow the text if the user resizes the parent form.
You want a text box, but set its Read Only property to TRUE, and maybe Enabled to FALSE
When using custom-draw (NM_CUSTOMDRAW) to draw the entire contents of a ListView SubItem (in Report/Details view), it would be nice to be able to apply the same left and right
padding in my custom paint method that is applied by the control itself for non-custom-drawn items.
Is there a way to programmatically retrieve this padding value? Is it
related to the width of a particular character (" " or "w" or something?) or
is it a fixed value (6px on left and 3px on right or something) or...?
EDIT: To clarify, I want to add the same padding to my NM_CUSTOMDRAWn SubItems that the control adds to items that it draws, and the metric that I'm looking for, for example, is the white space between the beginning of the 2nd column and the word "Siamese" in the following screenshot (Note: screenshot from MSDN added to help explain my question):
(source: microsoft.com)
Note that the word "Siamese" is aligned with the header item ("Breed"). I would like to be able to guarantee the same alignment for custom-drawn items.
use ListView Header message HDM_GETBITMAPMARGIN
see link text
ListView_GetSubItemRect (LVM_GETSUBITEMTECT)
http://msdn.microsoft.com/en-us/library/ms930172.aspx
Despite what the documentation says I suspect LVIR_LABEL returns just the returns the bounding rectangle of the item text, as per ListView_GetItemRect.
(This just kept niggling me as I though I had actually seen an answer somewhere when playing with NM_CUSTOMDRAW).
Edit After Comment 2:
I imagine you have seen NMLVCUSTOMDRAW which if you are willing to use Version 6.0. has rcText. I wouldn't since I use Win2K.
Given what you have found I would go back to the suggestion of using
ListView_GetItemRect to get LVIR_LABEL and compare that with LVIR_BOUNDS and use the difference.
the way for doing this is retrieving the format of the corresponding column with
ListView_GetColumn()
then check the retrieved myLVCOLUMN.mask
LVCOLUMN myLVCOLUMN;
myLVCOLUMN.mask=LVCF_FMT;
ListView_GetColumn(hwnd,nCol,&myLVCOLUMN);
then when we draw the corresponding label belonging to that column
if(myLVCOLUMN.fmt & LVCFMT_CENTER)
DrawText(x,x,x,x, DT_CENTER | DT_WORD_ELLIPSIS );
else if (myLVCOLUMN.fmt & LVCFMT_RIGHT)
DrawText(x,x,x,x, DT_RIGHT | DT_WORD_ELLIPSIS );
else
DrawText(x,x,x,x, DT_LEFT | DT_WORD_ELLIPSIS );
I would assume that GetSystemMetrics() is that you need to look at. I think that SM_CXEDGE and SM_CYEDGE are probably the values you want, but don't quote me on that. ;-)
Can only guess without seeing your output.
A few suggestions: If you are using the DrawTextEx function, have you have experimented with DT_INTERNAL et al?
Are you accidentally putting in a blank image/icon.
Does it look ok in classic screen mode? If so I would look at XP Theme functions to see if some thing is going on.
Late edit after first comment:
I wonder if the size of rectangle matches the space required for the LVN_ENDLABELEDIT edit box around the text so the text doesn't move (or for a focus rectangle)?
I guess you could compare the result of LVM_GETITEMRECT with LVIR_LABEL on the first column and use the difference as your left border.
