My application is written in delphi. For some reason the main menu does not behave anymore like it did until yesterday (I probably touched some property without knowing). Now when I click on a menu item with sub-items, though the arrow is located to the right, the submenu keeps opening to the left.
What is the reason and how do I restore it back?
As revealed in the comments to the question, this is not programming related. There's a setting that does this in tablet pc settings in control panel. The reason for the setting is, when one is using a pen or the like with the right hand, sub menus, if opened to the right of their parent menu, are obscured by the pen.
I had the same problem and it had nothing to do with my "touch screen" or other pc tablet related settings
I found out by changing some features of the MainMenu of type TMainMenu:
Just set the "OwnerDraw" feature to False and "ParentBiDiMode" to true
So if your parent view is already fine this MainMenu (submenu) will conform to its parent.
I did it 100s of times and it worked for me

Within the IDE, when F12 toggles between code and form,
the forms are displayed outside the monitor borders,
and therefore not visible.
This happens after a multi monitor setup has changed,
and the forms no longer open within the available new monitor screen areas.
One way to resolve this is to use the property inspector and
set the Top/Left properties to 4 to make the forms visible.
This is however a lot of work,
especially if many forms and possibly many projects are involved.
Is there a better way to reset the form locations once and for all,
so they are all visible with the new monitor setup?
There is nothing (AFAIK) in Delphi 6 IDE that would help. But assuming you are using Windows, the help is near, (tested on Windows 7):
Right-click on taskbar and select 'Cascade windows', this affects all windows in one go.
or
Alt-Tab to the window, press Alt-Space and then M (for move). Move the window with the arrow keys. This you would have to do seperately for each window.
Close your Delphi IDE. Then, if your current project group file is xyz.groupproj, open the file xyz.dsk with an text editor. Look for section [UndockedDesigner] entry "Count" and change its value to zero.
[UndockedDesigner]
Count=0
That will force all design window positions to 0,0 on your main monitor.
Two buttons on the view toolbar in Delphi disappeared and I can't get them back. One of those buttons is the one to switch between code/unit and the design/form view which I use all the time. The keyboard shortcut for switching (F12) still works, but I have one of those pesky media keyboards where you have to press a function key to access F-keys, so I'd really like to get that toolbar button back.
I tried resetting all the toolbars and their contents, and I see space where the buttons should be, but they aren't there. In the customize dialog for the toolbar, the commands don't seem to even be there anymore.
I tried doing a "repair" re-installation of Delphi, but even that didn't fix it. Has anyone else had this happen before, or have ideas on how to repair or reset my IDE?
edit: perhaps it's worth mentioning the menu options to toggle between code/unit and design/form view are also missing.
As best I can tell, this problem (missing view unit/form button and menu option) could possibly be a limitation of the starter edition of Delphi (this forum post: https://forums.embarcadero.com/thread.jspa?threadID=83324 ) seems to indicate an XE3 user with starter edition has the same missing buttons on their toolbar.
I did discover at the bottom of the screen there are tabs to switch between code, design, and history, which does at least give a mouse-based workaround to toggling between the views without having to expand the file view and click the right pas/dfm file. And the F12 keyboard shortcut does still work as well.
I encountered yet another problem with ribbon. When I have two forms (one of them is main) and I put ribbon on both of them, they behave strangely. When I open the second form by Form2.Show;, every time I click a ribbon menu button on the second form, it loses focus and the main form gets it.
This happens at pure blank project, so what could I possibly be doing wrong?
Here is a video, just in case: Watch YT
And to be clear, the Action1 button has only Caption:='a'; code.
The ribbon control assumes that there is only one per application, and misbehaves if it is not the only control. You could try to modify the Ribbon.pas code, but it is doing some hacks that probably rely on Ribbon.Parent being Application.MainForm only.
It not just my curiosity, recently I've received a bugreport concerning one of my AS3 applications. This bug can be reproduced only if the quality in flash player is set to LOW (HIGH/MEDIUM - everything is ok). The bug changes the application behaviour, but it's a mystery for me, why it happens only for LOW quality while quality is said to influence rendering and visual appearance, not the code or behaviour.
Briefly, I have a menu panel (MovieClip) with several items (also MovieClips). Very simple, it appears on a screen after a MouseEvent and a user moves a cursor from one element down to another. When the cursor reaches the edge of the second item, the menu suddenly disappears.
In my code panel hiding is set on mouse click or mouse out.
Personally, I think, that the problem is in Tweener, I have to use that old piece of code. The menu panel is shown when mouse is above a user icon, and concurrently with the help of Tweener I produce some simple effects on this icon.
I have explored adobe and firefox (my app is for web browsers and the bug is reported for firefox) bugtrackers, but so far I have found nothing. Maybe misbehaviour of flash player 11 with Arrays, already fixed... I've run out of ideas.
From the docs:
LOW
Specifies low rendering quality: graphics are not anti-aliased, and bitmaps are not smoothed.
If it only happens when rendering it set to low, then it's probably a timing issue - i.e., the bug has always been there, but because you're wrapping up rendering earlier, you can trigger then bug. Is the bug reporter's computer a slow one? Is there a lot happening at once? Is the menu being removed, set to invisible, or repositioned?
Like #jeremynealbrown said, try and separate out your class to a simple project to make sure there's nothing wrong with your logic there.
Another method, override the removeChild() method, and visible and x and y properties to see which one is setting it, then put traces before all calls that call these to see what's triggering it.
If you think the problem is in Tweener, add a MOUSE_OVER listener to the menu panel that calls something like removeAllTweens(), no matter the state of the menu panel. If the bug doesn't happen anymore, this will show you that it's related to the tween engine.
I am using the new BrowserField2 in BlackBerry OS5 to display HTML content in my app. There are 3 options available for navigation through links in that content.
CURSOR navigation uses a block cursor and actually moves through the characters of the page. Not very useful for me.
POINTER navigation uses a mouse like pointer that you move around the screen and hover over elements. This could work but there is a bug however in that the browser field captures navigation and never lets go so this mode is effectively broken if you share a screen with any other managers. Once your focus enters the browser field you cannot move focus back out and into neighboring fields. RIM has acknowledged the bug but has no work around.
NONE which is for custom navigation but they offer no explanation as to how you would do this.
What I ideally want is to simply have trackpad movements move the focus through the links and highlight them. Then a click would activate the link. I assume I would select the NONE option above and implement my own focus navigation but I am not clear how this can be accomplished with the new APIs.
Is anyone familiar with the new browser2 component could give some guidance?
Thanks!
There's a workaroudn to getting back the focus out of the BrowserField using the NAVIGATION_POINTER.
I found it in this thread:
http://supportforums.blackberry.com/t5/Java-Development/BrowserField-2-Navigation-Mode/td-p/632172
"farahh" posted this:
I found out a hack..
with the navigation set to pointer mode, a click outside the browserfield manager invokes Manager.invokeAction(int). I used the getFieldWithFocus to verify which field has focus and then switch the focus to something else.
Cheers.

PD: i havent found out how to get the behaviour you want, i need that as well so if you got it working please let me know, its kinda urgent in my project =(
I actually reverted back to the older browser1 (OS4) component because the navigation problems in browserField2 (OS5) were a deal breaker for me. Luckily the OS4 browser does everything I need in terms of functionality and it has the exact navigation behavior I need and there are no focus problems mixing it with other views.
