I'm searching for a gwt component with the following properties:
-Able to display Strings in a structured way, ie. username and message in seperate columns
-providing control over the scrollbar
In essence I'd like to have a component able to display more than simple strings and that auto scrolls to the bottom.
At first I used a simple textarea which fails to satisfy my first requirements. Additionaly I failed to implement the autoscroll to the bottom.
Are there any components which accomplish those features? Or if not, how could I create a similar component?
Create your own custom widget with the below or similar hierarchy,
Vertical Panel/Dock Panel: The outer container.
Header Panel: A horizontal panel with width set to 100% and add the required info. If using Dock Panel, set it to North
Scroll Panel : To get the infinite scroll and set its width to 100%
Horizontal Panel(s) : One panel for each chat string.

I am creating an event screen like Outlook's. The issue I am coming across is that the autocompletebox I am using from Syncfusion doesn't automatically grow in height as more tokens are added.
The current workflow is exactly like outlooks. When the control is clicked on, it brings you to another page where you can select tokens. On return, the selected items populate the autocomplete circled below.
The approach I currently took is to have a listview. Scrolling is disabled for the listview since the page resides in a scrollview and nested scrollviews aren't recommended for xamarin. The height of the listview is dependent on the number of selecteditems.
I am wondering if there's another approach or control that would be more suited for my situation? Or if someone has come across a autocomplete control where the height will grow.
Desired look
I wish to make a toolbar for my app that will contain some simple buttons, each with a single monochromatic icon. Here is an example of some toolbar buttons similar to I'm trying to achieve, from Mail's compose window:
Notice these buttons have a consistent size, inner padding, padding, and shading. This is a pretty consistent style across macOS, present in Mail, Safari, Finder, etc. This leads me to suspect there's a standardized UI component for creating such buttons.
If I use a segmented control, each button looks correct, with each icon being correctly padded:
Now I would like to add individual buttons that match the style.
Attempt 1
My first attempt was to add a "Push Button" (NSButton) to the toolbar:
This resulted in a wide button that's a bit too short, and not lined up with the segmented control:
Attempt 2
My second attempt was to use a segmented control, with only 1 segment.
This resulted in a button that's the right shape, size, etc., but it was off center relative to its label.
Naturally, I can manually adjust the button to match the goal, but I feel like I'm missing something. What's the proper way to create these standard buttons?
This is actually quite easy to do and you were close already.
You can use NSButton for that. Note that it has different styles (defined in NSButton.BezelStyle) to choose from. The default one is the one to use inside windows and modals. But for toolbars, to match the style of segmented controls and search bars, you can choose the style .texturedRounded.
You can also set the style via Interface Builder. Note that you have to select the button itself, not the toolbar item around it.
To get the correct size, you seem to set the icon within the toolbar item, not the button itself.
Here is my result:
My app's main window contains a Rebar control which contains a menubar band, a toolbar band, and a tab control band. When adding those bands using RB_INSERTBAND I have to pass a minimum height for the band in the cyMinChild member field of the REBARBANDINFO structure. Otherwise the Rebar control doesn't layout its bands correctly.
I can easily calculate the cyMinChild for the menubar and toolbar bands by simply using the TB_GETBUTTONSIZE message to find out the height of the menubar and toolbar.
For the tab control, however, things are more difficult. In fact, I'm unable to find any way of determining the tab control's header height. The problem is that initially, the tab control doesn't have any entries. If the tab control had some entries, I could just use TCM_GETITEMRECT to find out the header size but when I create the tab control and add it into the Rebar control, it doesn't have any entries yet.
So how should I find out the cyMinChild height for my tab control? Do I have to insert a dummy entry, grab the height using TCM_GETITEMRECT, and instantly remove the dummy entry again to achieve that? Or is there a nicer solution?
Note that I'm not using any toolkits. Everything is done in pure C so any solution should also be in plain Win32 API.
Thanks!
I have one WWSD or one SDPanel with some attributes but between these attributes that are fixed inside a Table or directly in the MainTable I want put and Grid, the problem is that the Grid is not showed and when I put the grid its no more possible scroll in the WWSD or SDPanel, is like the Grid stuck the SDPanel more than the grid is not showed.
Anyone can help me to put the Grid and keep with all normally ?
Thx.
I assume you're targeting Android.
The issue is that Android does not natively support nested scrolling. Therefore, a GeneXus layout that contains a grid will disable the form's own scrolling (so that the grid can itself scroll).
There are two ways of resolving this issue:
Redesign the panel so that the form does not vertically exceed the size of the screen (thus, form scrolling is not necessary).
Set autogrow=true for the grid, which will resize to fit all items (and "push down" any other controls located below it). Since the grid will no longer need to scroll, the form's scroll will be enabled.
How can I do something like that?
I didn't find any appropriate object in the Interface Builder library.
Any thoughts?
The best way that i found is to use NSSegmentedControl.
after you dragged it on the canvas, you should configure its style:
Style: Small Square
Mode: Select Momentary
looks better. Now use "image" field to set NSAddTemplate and NSRemoveTemplate. Make sure that label field is empty.
Ok, we have "+", "-" and one empty segment. To prevent the latest one to be selected by the user, select it from Segment: pop up and turn off Enabled check box (located next to State: label).
And lastly, what we have to do is set width of first two segments to make them square.
Go to Size inspector
Select Segment 0
Turn off "Fixed" checkbox (segment should immediately autoresize to fit image)
Select Segment 1 and repeat number 3
Now as you resize control, only last segment will change width
Put it at the bottom of your table view and resize as well.
Enjoy ;)
Update for OSX Yosemite
I tried to achieve the same look as Mail.app has in the Accounts view (right window on my screenshot).
I did achieve the desired result by following the steps below:
Add a NSSegmentedControl
Add two segments and set the image to each:
NSAddTemplate for the + button
NSRemoveTemplate for the - button
Set the size of the segments to fixed and set the value to 32 pixels
The rectangle next to the buttons is a NSButton with the style Gradient.
The Button is enabled but Refuses First Responder is set to true so that it is not clickable.
Use a NSButton with a gradient style, and for the images use the system provided NSAddTemplate and NSRemoveTemplate.
One answer here suggests using gradient buttons, however these buttons cannot be disabled as this causes the background to change and thus breaks the look. Another one suggested using a segmented control, which is almost perfect but segmented controls don't support autoresizing, e.g. if the table width is dynamic. My suggestion is a combination of both. Use a segmented control for the actual buttons and a gradient button to fill the rest of the table width that now can also be dynamic if the button width is dynamic as well.
