I just moved from Delphi 7 to 10.3 and was trying to install some of my older (VCL) custom components. I was finally successful in getting the code to compile, but I'm having trouble with something that seems like it should be trivial. The icons for the custom component(s) in the palette show what looks like a default icon instead of the icon(s) I expected. There are lots of posts on here (most are over 5 yrs old) about component icon issues and I've tried self-compiling the .rc file, including the{ $R .rc} in the package source and using the Project/Resources and Images dialog to specify the icons. I've tried 8-bit, 16-bit, 24-bit icons that are 24x24. Then as a test, I followed the exact procedure shown here which included some of the more recent content on this issue that I could find. I tried with bitmap files at full resolution and 32bpp and 24x24 at 8bpp. In both cases, the default icon showed for this test component. I'm probably overlooking something simple, but I'm kind of at a loss on what to try next. Is there a different procedure for specifying icons for custom components in 10.3 compared to older versions?
Edit: An update - I reinstalled my custom component and then rebooted and then was able to see the correct icon reflected in the palette, but here's where it gets strange. The test component I linked above still shows a default icon even after reinstalling and rebooting, and even stranger, is that the second I use my custom component on a form, the icon in the palette reverts to a TEdit icon (the component is a descendant of TEdit). Closing Delphi and reopening restores the icon until it is used again.
I'm not sure whether I should answer my own question, but just wanted to update in case it helps someone later. I was finally able to get the sample test component icon to show by using the -nocache option as described here. I then cleared the registry cache for my own component (dclusr) as shown in the same post and then also changed the bitmaps from 8bpp to 32bpp and now everything seems to be working as expected. I then cleared the registry keys for the sample project, and I can run without the -nocache option and all icons show fine, so I am thinking it was mostly a cache issue which I never would have found without the referenced post.

The editor for the GUI is a complete mess. When I create a brand new script, the spacing and font are relatively ok.
However, if I open any existing function, it is shown with way too much space between lines, and spaces and tabs show way more space than they should. An example is shown below:
I tried selecting the Edit - Preferences - General - Use custom file editor options, and chose "notepad++ -n%l %f. I have notepad++ installed already on my computer.
When I selected this option and clicked ok, the Octave GUI crashed. When I tried to reopen a file now, I get the error "could not start custom file editor".
If I change the font, it temporarily fixes the issue. But none of the changes persist. Often clicking OK crashes octave. And any time it's reopened, the fonts revert to default, and the spacing problems returns.
How can I make the editor show an appropriate leading and space width?
I would also like to be able to further customize, if possible. For example I'd like it to use a dark theme. But for now just showing a reasonable space between lines would make this at least useable.

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 just built a new system. (Win 8.1, 64 bit, D2010). Install went fine... adding some various VCLs. For some reason, in the Delphi Component Palette, all component glyphs PAST the 'Gestures' palette are all defaulting to the 'generic' icon. The first 13 tabsheets use proper icons. The remaining 30 or so tabsheets use the generic 'Blue box, red triangle, gold circle' image.
Delphi compiles my apps fine. For some reason the GLYPHs are just messed up. I have exited Delphi, restarted, even rebooted the machine. It was initially working fine, but then it messed up. So what did I do? I installed a few components, which I have installed before... I added some help files to the Windows help system for one of the components. I added some directories to the Delphi Path, and added a new BPL file for some of the components, and I went into the Tool/Options/Component Tool Bar and moved one component from a page by itself to another page. This left an empty page/tabsheet, so I deleted it. Thinking this might be the problem, I went back in and clicked on 'Reset to Default'. It did reset the one component back to a page by itself. Restarted Delphi... same issue.
UPDATED INFO***: Some Embarcadero supplied pages show fine, others show 'Unknown/Default' Glyph. For example, the first 13 pages are good, then are 10 or so pages bad, then SAMPLES, INTERNET, and few others are good. Pages that are bad include INDY (the whole set) and IW (the whole set). All my TMS stuff is good (which I installed). Some of the JVCL pages are good, some are bad. Interestingly, one page, Jv Edits, is half bad, then the rest of the page is good.
I don't know why, but when I switched back and forth to different IDE Layouts (Default Layout, Classic Undocked, etc) a few times, the palette glyphs got reloaded, and now everything looks as it should.
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.
I just activated the themes in my Windows XP (usually I work using the classic Win9x look) and I have seen that two panels are pure black. Other panels are ok (color = clBtnFace).
What these 2 panels have in common is their parent. Both are placed directly on a TForm. If I move them to a different parent (another panel for example) the have the appropriate color.

This is another grandiose Delphi bug. I started do delete stuff from my project and recompile the project. After one hour I finally went to the main form. I deleted the XPManifest control and now, magically, the program works.
The new issue (XPMan) is discussed here: TPanel color is black when I drop a XPManifest control on my form
Edit:
Removing the XPMan is not enough. You will have to delete also the RES files. For large applications it may take a while to manually reconstruct that file. Maybe it works to big into that file and manually remove the resources added by XPMan.
Make sure the panels do not have ParentColor=false and Color=clBlack assigned to them, and that ParentBackground=true is assigned.
