I have two forms in my project in c++ Builder 2010. I have created RadioGroup in the second and listed all my buttons there, but I have few problems:
When I load my form and check some button, the earlier selection stays checked until I hover mouse over it.
How to make the buttons from second form affect the first form?
How to make certain TEdit box go grey and unselectable when checking certain radiobuttons?
I found this by googling embarcadero radio, first hit: embarcadero docs
Essentially, radio buttons are not mutually exclusive unless you use a radio group.
Two questions in one is not a great idea, but to answer the second just set TButton->Enabled to false.

Is it possible to capture OnClick event when the CheckBox is disabled and then, to display a tooltip that shows why it is so (based on some business requirements)?
I looked up many sources over the internet, but I was able to find the answer to the second part of the question, not tested though. It seems to be a well-known problem, but I cannot find any answer or a hint.
I have to say that I am not a master of MFC, so a small code snippet would be appreciated.
I'm looking for a way of nesting comboboxes in my GUI application (or to be more precise, I'm looking for a way to have an item displaying similar visual and functionnal properties as nested comboboxes).
Looking first at all the functions provided by the combobox class, it seems comboboxes nesting it's not supported by Qt.
I therefore thought that another solution would be to create a "menu" item outside the menu bar. If I understand correctly this phrase from the offical Qt documentation, it seems to be feasiable :
A menu widget can be either a pull-down menu in a menu bar or a standalone context menu
Not sure though was is meant by the "context" word.
However, there is no such (menu) widget in Qt designer and I haven't found any good examples about how to do it on the internet (and can't get a menu not associated with a menu bar to be displayed on the windows), explaining why I'm currently doubting whether it's feasible or not with a menu item.
I would greaty appreciate if you could provide some code sample along your response.
EDIT :
To clarify my first post, I'm trying to do something similar to this app :
It's the application that comes along the 3D connexion mouse whose usage is to parametrize each button.
As you can see, there are several sub-menu items. By clicking on the arrow next to a textbox, you open a sub-menu containing itself folders that contains themselves paramaters.
I have been playing around with Editframe buttons in a Sitecore 8 for a multilingual project and I have the feeling that Edit Frame buttons do not work properly on sitecore multilingual sites.
Were you able to get it working edit frame buttons with a multilingual implementation?
Is it working out of the box or do you need any special configuration?
My experience is that when I am on a localized page and I click on an EditFrame button, it will open the default language Item instead of the localised item. I am of the impression that this is what happen when you click on Edit the Related Item in the Experience Editor.
I encountered your scenario very recently.
Were you able to get it working edit frame buttons with a multilingual implementation?
Yes, all the Fields I set up within the Edit Frame Buttons in the Core worked correctly with my Multilingual Site
Is it working out of the box or do you need any special configuration?
You need to add your Field Names into the Edit Frame Button Items in the Core database, found at the out-of-the-box path; /sitecore/content/Applications/WebEdit/Edit Frame Buttons/Default/Edit. Make sure your sc:Edit component references this path in the Buttons property
You may use different Display Names of the Fields for each of your languages for ease of use in the Content Editor / Experience Editor but as long as they are display Names it should be fine. If they are not and it doesn't work I recommend putting the Field Name for each language in the Edit Frame Item.
When I click on an EditFrame button, will it open the default language Item instead than the localised item, I am of the impression that this is what happen when you click on Edit The Related item as well
No, in both instances the Item will be loaded in the correct Language as well as when you create a new Datasource Item to be referenced by your Component.
The biggest issue that is present is when Edit the Relating Item and make changes to Rich Text Editor field or TreeEx field is that when you save it, it saves it to the default enlanguage, even creating a Language Version for it if it does not exist.
I have raised this issue with Sitecore Support and they are currently investigating. When they have a fix I'll update you with their solution.
EDIT
The Support Patch to resolve the issue Edit the Relating Item saving changes to the wrong language version of the Item can be found here - https://kb.sitecore.net/articles/814090
We have a list that uses a custom renderer containing a label, a checkbox and two icons (which have click events). This list needs to be made WCAG 2.0 compliant and in order to do that we need the list to be keyboard navigable.
The problem is with being able to move from one list item to the next and have the focus move to the label for the next/previous list item. Specifically, when the user enters the list using TAB button, the label for the first list item receives focus (highlighted box around text) and the entire row in the list is highlighted as the selected item.
However, when the user then presses the down arrow key to move to the next list item, the next row becomes highlighted (is now the selected item) but the focus remains on the label of the previous row (highlight still shown around label for row 1). The only way to get the focus to move to the newly selected row is to tab through the checkbox and two icons. This isn't a big deal if there are only a couple list items but would be a pain if there are 20+ rows in the list.
Is there a way to get the focus to move to the label of the newly selected row as soon as the user moves (using up/down cursor keys) to the new list item? I know a picture would help but I don't have anyway of posting a screenshot online. Any help would be greatly appreciated.
You're going to have to dig into how focus works in Flex. This is not a complete answer, but hopefully you can put together a solution that works for you. I did this about 4-5 years ago in Flex 3, but it should be similar in Flex 4.
How Focus Works in Flex
The main things to know are the FocusManager singleton class and the IFocusManagerComponent interface.
The FocusManager moves the focus around the UI based on user interactions (mouse clicks, keyboard navigation, etc.).
If a component implements the IFocusManagerComponent interface, then the FocusManager will include it in the "tab" loop and allow the component to be focused via keyboard navigation.
How Focus Works With Flex List Components
You've already stumbled onto the peculiarities of how focus works with the List component and item renderers. The Flex List components implement IFocusMangerComponent and so when you tab through the UI the FocusManager sends the focus to the list.
The List may or may not focus the item renderers. In Flex 3 you had to be using editable item renderers for this to happen, it may or may not be the same in Flex 4.
Some Ideas for Solutions to Your Problem
I think there are numerous ways to solve this. Use some combination of these techniques:
override the protected keyDownHandler() method of the List component. I don't have the code handy, but if you look at it's implementation in the List class you should be able to make your overridden version set the focus on the next renderer.
use methods of the FocusManager to find components in the tab loop: getNextFocusManagerComponent(), findFocusManagerComponent(). Check the docs there are others that will be useful. For example, when the user presses the down arrow, you can let the next item renderer get selected, then use findFocusManagerComponent() (passing in the newly selected renderer) and then tell the FocusManager to focus it with the setFocus() method. This is probably not exactly the right approach ;)
By the way, the FocusManger is a Flex singleton object, every UIComponent in Flex has a focusManager property you can use to get a reference to it.
consider disabling focus on objects that don't need to receive focus (like the Label in your item renderer). There are numerous properties to do this: focusEnabled, hasFocusableChildren, mouseFocusEnabled, tabEnabled, tabChildren etc.
consider disabling focus on the List component, but then making your item renderers implement the IFocusManagerComponent interface. Implementing the interface is simple, you just declare it in your class (there's no actual methods to implement). The tricky part will be now your item renderers need to have key down handlers (just override the protected keyDownHandler() method that all UIComponent objects have).
I think there are other techniques you can use, it's just been too long since I did this. I'd be happy to provide more help if you get stuck somehwere...
I have a CListCtrl with checkboxes. I want to be able to disable one of the items so that the user cannot click the checkbox. Is this possible? If so, how?
Edit:
Found the specifics on how to hide a checkbox in another question
Need only some rows in a CListCtrl control to have check boxes
Shortly: Not easily possible.
You'll need to sub-class the CListCtrl and implement this behavior on your own or download for example the MFC Grid Control that allows you to do that.
As for the removing check-boxes idea, yes, that might be possible, MSDN:
Version 4.70. Enables check boxes for items in a list-view control. When
set to this style, the control creates
and sets a state image list with two
images using DrawFrameControl. State
image 1 is the unchecked box, and
state image 2 is the checked box.
Setting the state image to zero
removes the check box.
