I am working on a win 32 sample. In that I am using List Box to Display the List of user. I am using the setting the owner draw flag to draw the items. It is working fine.
But I want to customize the scrollbar of the list view. How to do it.
Please let me know how to customize the scrollbar.
Scrollbars are usually native, even for custom draw items. If you really want to customize them, take a look at this library & tutorial.

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:
Our designer wants a unified toolbar/titlebar (such as what Safari, XCode, et. al use) but wants labels under the icons. I have the display mode on my NSToolbar set to IconAndLabel but I still only get icons... if I do separate title and toolbars the labels show up.
I've found nothing in the docu or even via googling that suggests you're forced into icon-only view but that seems to be the case. What's the best way to get labels on these buttons? I want to avoid putting the labels in my image assets as that will complicate localization, so if that's the only choice I'd have to do it programmatically using a localized string.
As far as I know there is no way of having both the new unified toolbar and labels. Maybe you could put a bar under the toolbar that contains the labels, aligned perfectly to the images.
But do you really need the labels? Apple is trying get rid of them with the new toolbar design. Try to make your icons as self-explanatory as possible. Don't forget that there are tool tips available as well for the button titles..
I am new to Windows Phone Programming. In my application, I Have a listbox which lists the phone contacts. Currently it is listed as a regular list with equal size for list items in the UI.I am looking to modify the front end like this :
I dont want to have different sizes /back ground color for each list items rather a fixed UI and let the lists scroll through it and the list item in the view, at any time, should be displayed as in the picture.
I dont expect any codes as answers but any examples are welcome too, just want to know using what feature this kind of functionality is possible so that i can do my reading!
Thanks,
Deepak
It would be difficult to modify an existing control (ListBox for example) to act like this, so your best bet would probably be an ItemsControl with its RenderTransform set as a TranslateTransform.
If you place a Rectangle (with Fill="Transparent") over the ItemsControl, you can attach handlers to the ManipulationStarted, ManipulationDelta, and ManipulationCompleted events to control the "scrolling" by setting the TranslateTransform's Y offset.
To resize the items in the list there are two options: a custom panel or manual setting.
Custom Panel
You could create a custom Panel implementation that will appropriately resize its Children based on a property you would create to represent the scroll position. Set the ItemsControl to use your panel, and either through binding or attaching a handler to the panel's Loaded event and keeping a pointer to the panel, update the aforementioned property from inside the ManipulationDelta handler.
Manual Setting
From inside of the ManipulationDelta handler, you can also calculate the various heights of the boxes and use MyItemsControl.ItemContainerGenerator.ContainerFromIndex to get the visual for each item and set its height.
I would suggest putting this all inside of a custom UserControl.
You may have issues with clipping using the TranslateTransform but hopefully this will get you started. Unfortunately, this looks like a rather difficult control to try making as your first windows phone project!
So Finally I did manage to find a way to do it.
First approach was as #Murkaeus suggested, Using UserControl and ManipulationDelta event handler. However for some reason the manipulationDelta event was triggered only for 2 finger gestures (Zoom, Pinch..etc), I have no clue why. And after some trying I had to give up on this.
The next approach was using Listbox itself. The source of the Listbox was set as the List( of Models objects) that I create after reading the contact information from phone. The height and color of the listbox item was bound to a property in my model named "scaleLevel" and was accordingly converted by implementing IValueConvertors to give predefined color and height values for different scale levels.
I created an attached property for the scrollviewer vertical offset like mentioned [here] (http://www.scottlogic.co.uk/blog/colin/2010/07/exposing-and-binding-to-a-silverlight-scrollviewer%E2%80%99s-scrollbars/)!
This event is triggered on change of the vertical offset and every time there is a scroll, I find out which listbox item to be enlarged and which reduced based current vertical offset.
Once I have this information, I change the property ("scaleLevel") of the affected items in the List (of Model) (which is bound to listbox height and color). This change is updated in UI using the INotifyPropertyChanged Event.
I have no idea if this the best way of doing it , but it works well and there is no considerable in updating the UI despite the processing involved.
I would like to hear your opinion about the implementation and any other solution which you feel will work better.
I have a registration form on my layout grid, made out of a stackPanel. Textboxes are taking most of the screen (800px) along with a button. When user is positioned in one of the text boxes, keyboard covers almost half the screen and in order to access boxes below, they first have to click somewhere blank to remove the keyboard and then click another box. It isn't possible to scroll down.
I want to enable same behaviour like when editing name in contacts, but didn't manage yet. How to achieve this?
Try wrapping it into a ListBox or a ScrollViewer (probably easier), like so:
<ScrollViewer>
...
</ScrollViewer>
Also, check to make sure you don't have the same problem described here.
I'm not a WP7 developer but here's what I do in Android and iOS and you may get a hint of what to do.
I wrap my forms in a Scrollable View. This gives easy scrollable features to users without the need of anything else.
I am tryimng to make a UI. But in qt, the window size is too short, I want to work in a separate windows like photoshop. Here I am posting the picture. I want to see the middle window(i rounded it by rose color) in full screen size. Can anybody help me?
EDIT:
If I want to create a full screen application, How can I position the widgets in it. It's possible dragging a widget inside a scroll bared window,but is not user friendly. I want it to work like photoshop, like separate windows.
If you want to have more space to work on the design of your widgets, you can open QtDesigner separately and maximize the design area. Panels can be closed and undocked.
Now if you want to maximized only the central widget, there is a trick:
Create a custom widget and work on it in QtDesigner. You will be able to put it in near full screen by increasing its size
Set your custom widget as central widget in your GUI application.
Previous answer before edit:
Hi, If you want to view your widget in fullsreen mode, you can call the ShowFullScreen function. If what you want is to maximize the widget, you can call the ShowMaximized function.
