I have a form that correctly displays component borders most of the time.
However when I tab out of the form’s first input field, the borders of all the form’s TDBEdit/TEdit components disappear. The component’s border’s reappear when moused over.
I can reset these at runtime by looping through the form’s components and setting TDBEdit/TEdit borders (BevelInner: bvLowered, BevelOuter: bvRaised).
Also, this issue appears to have something to do with the Enable runtime themes option in the Project Options. The issue only exists when this option is enabled and regardless of the Windows Theme that is being used.

After some additional research it appears that this is a known issue and occurs predominantly when a user is using the ALT button.

Running windows 10 21H2. Just upgraded to Delphi 11.2 (from 11.1).
Speedbuttons (with Flat=False) do not show the button rectangle at design time. It does appear at runtime.
Most/all of our VCL projects have an empty style name. I have noticed that if I set the Stylename for the button (or even the form), then it shows normally. But is this the best way of handling it? Is there a global setting somewhere that can restore "normal" behaviour?
In 11.2 the Form Designer Options have a new option Mimic the system style, which is active by default. Disabling that should solve your problem.
Form Designer Options
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.
As per my previous question (Delphi 6 support for toolbar and menu icons with alpha channel transparency), we are updating a legacy application developed in Delphi 6 to support Windows Visual Themes by including a Manifest. This has worked well and we have the majority of controls adopting the Windows visual theme correctly.
However, we do have a problem with TDateTimePicker behaving in a slightly odd manner. We have the form colour set to white (RGB 255/255/255) and the input box for TDateTimePicker is not visible on the form until it is clicked into and has an entry in it. Please see screenshots below:
Changing the form colour to grey, we can see that the box is there when not selected, it just has no border drawn around it:
We have been unable to find a property that will change this behaviour. Can anyone shed some light on why this might be occurring, what property needs to be changed, or another method we could possibly use to resolve it?
I have a TListView in vsSmallIcon mode. If I populate it with 2 items and first item text is longer than second item text it will draw first item over the second.
Is there a quick way to replace longer items with ellipsis? Or a complicated one?
I am using Delphi 2010 and C++ Builder 2010 with default settings of TListView
How it looks:
How I want it to look:
Edit: After trying out vsList style I discovered that the above is no longer an issue and it works without any additional code (no ellipsis but no items clipped also).
When working with TListView I often find myself investigating and mimicking the behavior of Windows Explorer.
Regarding your question with ellipsis in vsSmallIcon mode I checked out Explorer. I observed that when I resize the window there’s no ellipsis drawn for item captions. Instead the items are rearranged instantaneously. My suggestion would be to skip the ellipsis strategy because Microsoft has not implemented Explorer that way and chances of a quick fix for you decrease. If you can settle for rearranging then the two following “quick” alternatives should do the job, at least in XE3.
Alt 1:
ListView1.IconOptions.AutoArrange := true;
Alt 2: (must be called explicitly every time you desire a rearrangement):
ListView1.Arrange(arDefault);
Update:
I fired up Delphi 2006 and can confirm that the above methods work there as well
Have you seen this?
I have a little utility application (for easy load / test xml generation from CDS and/or DBGo), and I had put some buttons (the poorest button of all, TButton) to trigger some actions.
I never paid attention to appearance, because I'm the only one that uses it. So today I added a new button, and they appeared different from the others in designer - but not when running. It's just an copy and paste process (change the button name, caption and event - the rest is equal to the origin).
When I looked the other buttons have an grey gradient and round corners, the button I copied and pasted not (just a bare rectangle). When running all buttons where just bare rectangles.
So I discovered that on designer, W7 and delphi are applying themes. On running, they are obeying the Project/Options/Application/Enable runtime themes flag.
This is annoying. There's a way to make Delphi doing that obeying the project options flag on forms designer?
(Or even manually if is not possible to automate that)?
EDIT:
The toolbars on the form are from CNWizards ;-)
EDIT II:
Apart of disabling themes for the IDE executable, all buttons get themed equally if the form (or project) is reloaded. But it's really weird.
If you want to enable/disable themes in the IDE, then open the properties of bds.exe, select the 'Compatibility' tab, and make sure that the 'Disable visual themes' checkbox is unchecked/checked.
Programs that you run from the IDE will inherit the compatibility settings of the IDE.
Delphi IDE itself is an application and the way the designer draw the form is using the setting for the IDE application (delphi32.exe or bds.exe's compatibility settings) so the answer is no. The default behaviour is different between IDE versions, for eg. the opposite behaviour (not drawing themed) happened in past.
