I am inheriting the maintenance of a few stacks.
I have two stacks called “AI Frames 5.0” and “Flex Frames 5.0”. I thought the two stacks were nearly identical. Not the case. Option menu buttons are behaving differently between the two. STACK properties between the two stacks are the same. BUTTON properties between the two stacks are different.
The button on “AI Frames 5.0” has a property inspector title of button “Lamps” and HAS the Menu Items list that can be updated.
The button on "Flex Frames 5.0" has a property inspector title of card button “Lamps” and does NOT contain the Menu Items list.
If I drag out an option menu button onto each of the stacks, the new buttons “Look” the same but their properties are not the same – one is a card button, one is a button. (Same thing happens for other field types dragged onto stack.)
When I look at the project browser the buttons are listed in the tree in different locations. (image of project browser is included 1)
AI Frames 5.0
|_ AIFrmEst
|_ Button1
Flex Frames 5.0
|_ FlxFrmEst
|_ Button1
Is there an explanation to all this? My main problem is that I need to change the menu options for the button on the “Flex Frames” stack. How can I get “Flex Frames” stack to be similar to the “AI Frames” stack?
What happens if, from the Message Box, you do this:
set the text of btn "lamps" to "This"&cr&"That" -- replace with your desired list
I recently updated some very old stacks (Rev2.something) and buttons were all listed as "card buttons" in the browser, and fields as "bkgnd fields". Cloning the stack brought everything back to normal, tho I don't know if it will fix the button style as you want.

I am making an android application.
There i want a common navigation menu on every activity like frames in html.
I want the menu at the left (say 20%) area and other navigation screens on the right (say 80% area)
please help me out.
You should use two fragments, that way you keep the menu in one fragment and only change the activity in the other, I should not be difficult to find an example on internet since it is very common in tablets.

I have a MFC dialog based application. User can change the language of the dialog, and I made this by closing existing dialog, and opening another with changed language. The problem is that the effect in the taskbar is that one icon is removed, and another identical is created in its place. If my application's icon is not the last icon in the task bar it will be perceived as it was moved to the end of taskbar icon set.
I want to retain icon's position in the taskbar, and rather to prevent icon flicker at all from happening. How do I do that?
The application must support OS'es from Windows XP to Windows 7.
EDIT: alternative question for which I would accept an answer is how to create an invisible window that is nevertheless shown in the taskbar, and how to forward relevant window messages from that window to my main window?
Make the dialog a child of another outer parent window. The parent can be a dialog or any other kind of window; all it will be providing is the title bar. If the user tries to resize it it will have to forward resizing commands to the dialog, but otherwise you shouldn't need to do much in the parent window.
Why not replace the dialog with a CFormView instead? That way there's a frame window that wraps around the dialog (which is embedded in a form view) and it's the frame window that owns the taskbar icon.
Create an SDI application that displays a CFormView. Display the dialog in the default language (or whatever langauge the user previously chose) on initialization. When the user chooses the 'change language' option, simply change the form view that's being displayed with a new one.
Bonus feature: with this design, the framework will take care of things like language-specific accelerators and menus for you with no effort on your part.

I have a Windows form, and on it I dynamically create a number of widgets (toggle-boxes in this case). I can create anything from 0 to 64 widgets, depending on how many do-hickies the user has in the current collection. As the user changes from one collection to another, the widgets are deleted or created as needed. The form will resize according to how many widgets are displayed.
The user can check any number of them and perform certain processes on the checked items by selecting actions from a menu bar, toolbar or keyboard shortcuts. But I also want the user to be able to right-click on a single widget, which should bring up a popup menu with actions that can be performed on just the one clicked item, whether it's checked or not.
In itself, this is pretty straight forward. In the past I had done this kind of thing (in other languages) by having a single popup menu that pops up when the user clicks on any one of the dynamic controls. But I'm having a hard time doing this simple thing in Progress:
I am unable to have one popup menu that responds to the right-click of all the widgets. I tried creating a single popup menu, and then as I create each dynamic widget, I set its popup-menu attribute to this menu. The problem is that a menu can only be applied to one widget. Once I've assigned it to Widget1, I cannot assign it to Widget2. This leads one to think of creating a seperate but identical menu for each widget. And as the widgets are destroyed and recreated, so will these menus. In a single session I will create and destroy hundreds or even thousands of these identical menus, while the user might use one of them once or twice. Or not at all. So this does not seem like a good option to me.
My next solution would be to create a single menu which I can pop up programatically, but all attempts to programatically pop up a menu have failed. I have tried APPLY "MENU-DROP" TO MENU MyMenu and other similar things and I cannot for the life of me figure out how to do it. I also find it very difficult to search for information on this. It's as if nobody else has ever tried this, and the rare cases where someone has asked about it, there has been no satisfactory answers. I'm suspecting this cannot be done.
While trying all these things, I have also had endless problems with the events MOUSE-MENU-DOWN, MOUSE-MENU-UP and MOUSE-MENU-CLICK. MOUSE-MENU-CLICK seems to never happen, not for my dynamic widgets anyway. I am unable to figure out why. MOUSE-MENU-UP occurs sometimes, but it depends on what happens in MOUSE-MENU-DOWN and other events of the widgets as well as the widgets' parents. I have not been able to figure out exactly when it will or won't fire, it's very counter-intuitive. MOUSE-MENU-DOWN is the only one I can count on firing.
So: I can't show a menu programatically, I can only show it by right clicking on the menu's parent. The only way to avoid having hundreds of identical menus, is to have a popup menu on the parent of the widgets, for example the default frame.
With a static popup menu on the default frame, I can right-click on the widgets and the menu will come up, but it comes up if I click anywhere in the frame. I can disable the menu, and then in the right-click event of the widget, I enable it. This works very well the first time; if I click anywhere in the frame, nothing happens (the menu is diabled), but if I click on my widget, the menu is enabled and pops up. Yay! But now the menu is enabled and now it pops up if I right-click anywhere, on buttons, empty space, progress bars, etc. When do I disable it again? After the menu has popped up, the user can click anywhere and the menu will dissappear. There is no event that fires when the menu is closed, so I'm stuck.
Sorry about the long ramblings, I'll restate the question briefly: I want to have one popup menu that pops up when the user right-clicks one of a number of dynamically created widgets.
Using Tom's answer, this is how I implemented it:
/* Somewhere in Control Definitions... */
DEFINE MENU m_Popup
MENU-ITEM m_Test1 LABEL "Test 1"
MENU-ITEM m_Test2 LABEL "Test 2".
/* Somewhere, where I need to dynamically create the widgets. */
/* Loop through the items in the temp table and create a widget for each. */
FOR EACH ttItem BY ttItem.ItemName:
CREATE TOGGLE-BOX hWidget
ASSIGN
FRAME = FRAME DEFAULT-FRAME:HANDLE
LABEL = STRING(ttItem.ttItemName)
TRIGGERS:
ON MOUSE-MENU-DOWN PERSISTENT RUN GetMenu IN THIS-PROCEDURE.
END TRIGGERS.
END.
/* If the user right-clicks on any one of the widgets, this procedure */
/* is run with SELF being the widget that was clicked on. */
PROCEDURE GetMenu:
/* Remove the menu from its current owner and assign it to SELF. */
MENU m_Popup:OWNER:POPUP-MENU = ?.
SELF:POPUP-MENU = MENU m_Popup:HANDLE.
END PROCEDURE.
/* The user clicks on one of the menu items */
/* Here SELF is the menu item that was clicked. I can */
/* get m_Popup from SELF:PARENT and the widget it was */
/* was assigned to from SELF:PARENT:OWNER. */
ON CHOOSE OF MENU-ITEM m_Test1
DO:
MESSAGE "You selected " SELF:LABEL " for " SELF:PARENT:OWNER:LABEL.
END.
My buddy Mike Fechner (who is not currently on SO but who does this stuff a lot more than I do) tells me that, while this example is static, something very similar should work:
Procedure getMenu:
DEFINE INPUT PARAMETER phWidget AS HANDLE NO-UNDO.
DO WITH FRAME {&FRAME-NAME}:
FILL-IN-1:POPUP-MENU = ? .
FILL-IN-2:POPUP-MENU = ? .
FILL-IN-3:POPUP-MENU = ? .
END.
phWidget:POPUP-MENU = MENU POPUP-MENU-FILL-IN-1:HANDLE .
END procedure.
ON RIGHT-MOUSE-DOWN of all three fill-in’s you "RUN getMenu (SELF)." to steal the popup menu from whomever has it.
I have this main window on which I would like to put 2 widgets on the same space, i.e. when the user clicks a button then one of the widgets should come up front and the other be hidden and then change places when clicking another button.
My Widget are of different types: one is a QGLWidget and the other one is a QGraphicsView.
How could I put these 2 widgets on the same place?
Use QStackedWidget. Qt Doc says that :
The QStackedWidget class provides a stack of widgets where only one
widget is visible at a time.
Using LWUIT framework to develop mobile application.
In LWUIT by default first command is placed in the left and subsequent commands will be placed in the right menu of the form including the command which is already placed in form left.I need to add two menus to form.Left menu contains general application specific commands such as "Minimize","Back" and "Exit". Right Menu contains screen specific commands such as "Play Audio","Play Video" etc... Initially left softbutton of the form contains the text "Options" and the right softbutton of the form contains the text "Menu". When user selects "Options", a menu will be displayed with the following commands:
Minimize
Back
Exit
When user selects right soft button "Menu", a menu will be displayed with screen specific commands:
Play Audio
Play Video etc...
Commands of the right menu keeps changing from one form to another form, whereas the commands of left menu remains the same for all screens(forms). I know command menu can be customized by overriding "Form.createCommandList(Vector)" which returns a list. But here in my case I need two lists(menus). One at the left of the form and the other one at the right of the form.Please do help me in resolving this issue.
A LWUIT menu is just a dialog containing a List (or buttons for touch menu or pretty much anything you want), so to implement this just create a Command called options and place it in the left soft button. When options is pressed just show the dialog with your "additional commands". Since a List can accept a command array or vector doing something like this can be really easy.
You can look at the code for MenuBar which is pretty simple, you can also replace the menu bar component in the latest version LWUIT (SVN at the moment) but that seems redundant for this particular use case.
