I'm still new to rebol and programming in general, and I'm trying to write a program for practice.
In this program, there is a main window, which includes a button with which I want to open a new window, and close the main window at the same time.
Now, I know how to do each function separately, but how do I combine them together?
This is what I tried:
button "Start" [view start-win unview main-win]
What's happening is that start-win opens when I click the button, then immediately all the windows close.
view starts an event loop - so no code executes after that until the window view opened closes.
To start a new window without that happening, use view/new - then to start the event loop when you are ready, do-events
unviewremoves the last added window and does not take any arguments by default. To close a specific window use with refinement unview/only window-name
So in your first case you create a new window and next close it. In the other case you start closing the last created window and next create a new one.

I want that when I click a button in the main window, it will go to the second window. I used the hide function and hid the main window, but when I finished the process on the second window, I want to return, but when I exit the second window, the program is already ending, because the first main window was already ending when I was in the second
We have a VB.Net Application with a Main form that should always be visible. However, we want to be able to display a succession of two dialog windows where we can close the first dialog as the second one appears. However, when doing that, the Main form gets sent behind whatever other applications are open and does not re-appear until the second dialog window closes.
We can correct this issue by keeping the first dialog window open behind the second one, but it’s not ideal. What are we doing incorrectly?
Try using dialog1.owner = mainform
I'm open a modal dialog box using the next code:
call screen 0010 starting at 15 1.
However it disables the main window to continue working.
It's posible to call a modal dialog box and enable the main window to work while it's opened?
The very nature of a modal window is that it blocks the application until it is closed. The opposite would be an amodal dialog, and no, you can't have an amodal modal window. What you can do:
CALL FUNCTION 'Z_FUNCTION_WITH_DIALOG' STARTING NEW TASK 'FOOBAR' - this will start an additional external session (as long as the user has not exceeded the session limit).
Use the class CL_DGUI_DIALOGBOX_CONTAINER to produce an amodal window. Be aware that you can't use screens (dynpros) inside this container. Check the report RSDEMO_DIALOGBOX_CONTROL for some example coding.
I have an application which displays a window containing widgets every minute. If I destroy this window by closing it in the window manager (linux), the destroy signal is sent. Then the next minute rolls around, at which time self.window.show_all() is executed and the window pops up empty.
So I did some investigating. I executed print self.window.get_children() just before the show_all command, which returned an empty list. So I executed self.vbox.reparent(self.window) and I get this response:
calendar.py:237: GtkWarning: IA__gtk_widget_reparent: assertion `widget->parent != NULL' failed
self.vbox.reparent(self.window)
These two responses seem to contradict one another. On the one hand, the empty list returned by print self.window.get_children() seems to imply that the window does not have any children. On the other, the output returned by self.vbox.reparent(self.window) seems to imply that self.vbox still has a parent, which would be self.window (as defined previously)
I've tried using a popup window: self.window = gtk.Window(gtk.WINDOW_POPUP) instead, but I would like to be able to close the window through the window manager, so that I don't have to add an additional button just to close (hide) the window. The popup window doesn't seem to provide this functionality in my window manager (awesome).
So if you want to redisplay a top level window with its children after it is destroyed, how can this be done?
Have you tried making another copy of
the window class and showing that one
instead? Note: This will reset anything that was set in the window. i.e. if a person did something to make label1 say 'Hi!' instead of 'Hello!', it is going to be reset again to 'Hello!', since you are recreating the window.
You can also set Gtk.Window.hide_on_delete as the handler for the delete-event signal; then closing the window will hide it instead of destroying it.
I need to create a form where AlwaysOnTop = True when the browser is visible. This creates some sort over "overlay". The logic works like this:
The program checks which window is active.
If the active windows is a certain process, my form will initialize the TopMost utility, and be the active window itself.
When the certain process is not the active window anymore, my form will disappear.
How I did it:
My program checks if a browser is the active window, if so: the form gets topmost and the program stops checking what the active window is. (because my topmost form is the active window now).
Now the program needs to check what the window under my form is, the second active window.
If it's not the browser anymore, the form needs to hide, and the program will check what the active window is again.
I already completed the function that checks what the first active window is,
I'm stuck on getting the function that checks what the second active window is.
I'm not sure that there's such as thing as a "Second active window" - its either active or its not.
Why don't your leave you active window checker running after the first step of detecting the browser.
You can detect when the active window is no longer your form and hide your overlay then.
