When we work with Entries and Textviews in GTK, it's possible for the user to add emojis in the text content, by just clicking with the mouse right button on the widget, then clicking on "Insert Emoji". My question is: how to remove emoji insertions in Entries and Textviews in GTK? I am using Gtk 3 + C programming in a GNOME desktop, but other languages might have similar solution.
See an image about the issue:
You can remove the option with gtk_text_view_set_input_hints (view, GTK_INPUT_HINT_NO_EMOJI) for GtkTextView and gtk_entry_set_input_hints (entry, GTK_INPUT_HINT_NO_EMOJI) for GtkEntry
If you don't want to modify existing input hints, you can do gtk_entry_set_input_hints (entry, gtk_entry_get_input_hints (entry) | GTK_INPUT_HINT_NO_EMOJI)
in GTK4, gtk_text_set_input_hints() can also be used where it's applicable

I am using SWT tables in my project and there are few columns which are having longer strings which are not completely visible by default (for ex. path to a file location). Though I have tooltip to show the content and using mouse we can increase the column width to see the complete value.
Is there a way to do it with only keyboard usage?
Note: This question is more related to accessibility.
The following answer is based on my experience under windows. It can be different for other OS.
I'm afraid that there's no keyboard-only default way to adjust the size or reorder the column in a table, tree view or list view.
This is true not only with SWT but also with all other frameworks based on native win32 such as wxWidgets.
You must provide a keyboard-only way to resize and reorder columns yourself. here are a few ideas implemented by some applications:
Provide an option somewhere in the application that opens a dialog box with a checkbox list of the different columns. Ctrl+Up/Down to swap two items. Check/uncheck an item with spacebar to make the column visible or invisible.
Make the headers focusable. Use Shift+Left/Right to resize, Ctrl+Left/Right to swap two columns. Application key / Shift+10 opens a context menu where you can check/uncheck columns to show/hide and an option to open the column selection dialog box.
Some screen readers allow to do it by simulating mouse operation in some way. For example, use Jaws cursor, click lock on a header, release lock on the header to swap with.
But it's quite complicated, not always reliable, and thus very rarely actually used.
This is a very good question. I would be happy to give 100 rep to someone giving an answer being for windows and:
generic, working by default, everywhere or in most cases
Independant from screen readers (Jaws, NVDA, etc.) and techniques that simulates the mouse with keyboard (mouse keys)
Unfortunately, I don't think it exists.
I am using RadListBox to show a list of items. Each item has an icon. The requirement is jumping on the item when a the first letter of that item is pressed.
For example: It should focus on "Dock" when letter "D" is pressed
Is there any built-in feature to accomplish this>
This functionality is built into the RadListBox right out of the box.
You must have the list box focused and then type a key to select the item with the first letter matching the key that was pressed. In order to focus on the list box you can either: click with the mouse, tab to it, set focus in JS, or use the KeyboardNavigationSettings.CommandKey and KeyboardNavigationSettings.FocusKey to help aid with keyboard navigation.
Example:
RadListBox1 = new RadListBox()
RadListBox1.KeyboardNavigationSettings.CommandKey = KeyboardNavigationModifier.Alt;
RadListBox1.KeyboardNavigationSettings.FocusKey = KeyboardNavigationKey.L;
You can also use EnableMarkMatches to highlight more than one match if necessary and for typing more than one letter for selecting.
Reference: Telerik RadListBox Keyboard Navigation Demo << This has all the sample code you should need.
Seems this a Telerik bug, but i made a project, test situation and it's working.
download sample project here.
this project tested on google chrome Version 60.0.3112.113 (Official Build) (64-bit)
After run project press Alt+s or Alt+o or Alt+c
Remember change AccessKey property to change shortcut key:
RadListBox1.Items[0].AccessKey = "s";
I should say that this NOT a perfect solution.
RadListBox is a powerful ASP.NET AJAX control to display a list of items. It allows for multiple selection of items, reorder and transfer between two listboxes. Drag and drop is fully supported as well.
I'm working on a Mac app that allows rich-text editing in the description of an item, including list items.
All of that is working fine, but by default NSTextView allows the user to select and edit the list markers just like normal text. I want the text view to behave like notes, where list markers are not selectable.
Here's an NSTextView (from TextEdit):
and here's the same in Notes:
I'm able to get close by overriding -[NSTextView setSelectedRanges:affinity:stillSelecting:], and removing the marker ranges. Unfortunately that interferes with many standard editing actions, including the arrow keys.
I could certainly override those actions (defined in NSResponder), but that's starting to seem like a lot of work. Is there a simpler way?
I have a CListCtrl control that has 2 columns and any number of rows. I want the user to be able to click(or maybe double-click) a "cell" and be able edit the text therein.
What I mean is that I want to be able to click and edit any of the places where it says "TEST" by clicking on the text to make it editable.
How should I go about this? I suppose I should use a mouse click event but how would I make the cell editable?
This looks like a list control in report mode, which is different from a list box. A list box doesn't support editing contents at all. You can write code entirely on your own to get the contents of a line, copy that to an edit control, display the edit control exactly where the existing content was shown, allow the user to edit, and copy data back when/if the user hits return.
A list control allows editing of one (and only one) field. If you want to support more, you have a couple of choices. One would be about like above, creating your own edit control in the right place. The obvious alternative would be to look up one of the many grid controls. CodeProject has a number of variations.
Drop-down lists, menus and combo boxes are all very common user interface elements. Users are accustomed to seeing these elements in native applications and sometimes web apps, but there are a few problems with them.
You have to aim the mouse. Some menus collapse when you mouse out, and some have submenus that you have to aim at to expand.
You can't see the options without aiming the mouse first.
These are the main things that trouble me, maybe other people notice other issues as well. I normally don't use drop-down menus at all if I can help it.
The problem is that I sometimes want to present a long list of options in limited space. Issue 2 is a sacrifice I'm willing to make, but I'm wanting to know if anyone has any tricks to make these drop menus easier to use. Maybe someone has invented a new style of list control.
I'm sure that if these types of controls annoy me, then they annoy users of my site more.
Hmm..one more thing which annoys me about the dropdown list is the inability to control their width as it expands with the text (or is their something which I am unaware of ?).
For an alternate, I think about a little popup which initially displays a list of available options in form of Alphabetic index and when the user clicks on an alphabet link, it displays the relevant options to select from. This will reduce the options to select from.
On the same terms, we can use ajax to build the options on the fly as user types in.
You could try something like Mac OS/X has for its taskbar, similar to the selection bar in YouTube. I think the common term is a bubble bar where small images animate larger as the mouse rolls over them, but shrink back down to such a size that all items are visible when the mouse is not over the control.

width='20px' will keep the collapsed drop down at a width of 20px. Problem is, Inernet Explorer shows the expanded item with this width also, while all other browsers i met so far will show you the full menu.
