GUIDarkTheme UDF

[argumentum]

hmm, reboot and test again. Not to turn a blind eye to the issue but to troubleshoot it.
Since all this is event driven, you'd have to "activate the child GUI or click on it with the mouse" to create an event.
So, rebooting shows if the OS is resource starved ( to give it a name ) or not.
In either case it could use some rethinking/pondering but the reboot is a good "retry" to look at what is causing the event/"white line" 🤯

The white line remains until I activate the child GUI or click on it with the mouse.

This usually happens when the child GUI is shown with @SW_SHOWNA.

I have a fix for this now. I will put together a release in this morning.

It looks like the devilish white line has disappeared.

Hi,

why the split button disabled have a vertical bar highlighted?

The 3.1.1 need #forceref $iD, $pData and Local $hDC, $hBresh defined before Switch

I had a look in the theme resources and this seems to be a Microsoft bug in their theme files. I think that the only way that I can fix that vertical bar highlight issue is by subclassing the splitbutton control. This will take some time but I will see how easy or difficult it is to fix.

Thank you for letting me know. I will have this fixed in the next release.

I have added the AutoIt3Wrapper_Au3Check_Parameters back into my testing script so that I do not miss these again.

In versions 3.1.0 and 3.1.1

The "GUICtrlCreateCombo" function: If the parameter "BitOR($CBS_DROPDOWN, $CBS_AUTOHSCROLL)" is set, the "GUICtrlSetData" function will have the correct value.

The "GUICtrlCreateCombo" function: If the parameter "BitOR($CBS_DROPDOWN, $CBS_DROPDOWNLIST, $CBS_AUTOHSCROLL)" is set, the "GUICtrlSetData" function will have the incorrect value.

Please fix this error, thank you.

Please see the details in the following two images.

Thank you for reporting this bug.

I was able to reproduce the bug and found the source of the problem. I will have a fix in the next release.

I have looked into this issue and would like your opinion, please.

The good news is that I can set a custom ImageList and draw our own arrow glyphs which fixes the problem with the arrow glyph.

The bad news is that I have no idea how to target the vertical split to fix that part.

So I have an idea. We can draw our own glyphs to have a nice, consistent arrow dropdown image. My idea for dealing with the vertical split issue (when disabled) is to simply hide the vertical split. This is the only method that I know so far that works.

Screenshot:

Please let me know if you think that hiding the vertical split (when disabled only) is an acceptable workaround or not.

GUIDarkTheme 3.2.1

• Fixed some visual glitches with BS_SPLITBUTTON controls
  • Most notably, disabled BS_SPLITBUTTON controls were incomplete within MS theme files

Latest download available in the first post of the topic.

 

@jpm This release should fix the issue that you mentioned with disabled BS_SPLITBUTTON control having visual glitches. The reason is because Microsoft did not complete the BS_SPLITBUTTON resources for disabled state.

So I fixed that disabled state issue and made it better overall, including light mode too.

Thanks

You still need to fix unused var warnings (#forceref ...)

also need tidies

Regarding custom buttons. It only works for regular buttons (not splitbutton, etc.). You can change the fill color and border color for all five states and you can also change the corner radius to make them as round as you want or squared.

You would need to enable the custom buttons first:

$__DM_g_bCustomButtonsEnable = True
$__DM_g_iCustomButtonRadius = 6

And here are the colors for all button states (current matches DarkMode_Explorer theme colors):

Global $__DM_g_iBtnBkColorDef,      $__DM_g_iBtnBkColorDefDark  = 0x333333,     $__DM_g_iBtnBkColorDefLight  = 0xF4F4F4
Global $__DM_g_iBtnBkColorHov,      $__DM_g_iBtnBkColorHovDark  = 0x454545,     $__DM_g_iBtnBkColorHovLight  = 0xE0EFF9
Global $__DM_g_iBtnBkColorSel,      $__DM_g_iBtnBkColorSelDark  = 0x666666,     $__DM_g_iBtnBkColorSelLight  = 0xCCE4F7
Global $__DM_g_iBtnBkColorFoc,      $__DM_g_iBtnBkColorFocDark  = 0x333333,     $__DM_g_iBtnBkColorFocLight  = 0xF4F4F4
Global $__DM_g_iBtnBkColorDis,      $__DM_g_iBtnBkColorDisDark  = 0x333333,     $__DM_g_iBtnBkColorDisLight  = 0xF4F4F4
Global $__DM_g_iBtnBorderDef,       $__DM_g_iBtnBorderDefDark   = 0x9B9B9B,     $__DM_g_iBtnBorderDefLight   = 0xBCBCBC
Global $__DM_g_iBtnBorderHov,       $__DM_g_iBtnBorderHovDark   = 0x9B9B9B,     $__DM_g_iBtnBorderHovLight   = 0xBCBCBC
Global $__DM_g_iBtnBorderSel,       $__DM_g_iBtnBorderSelDark   = 0x9B9B9B,     $__DM_g_iBtnBorderSelLight   = 0xBCBCBC
Global $__DM_g_iBtnBorderFoc,       $__DM_g_iBtnBorderFocDark   = 0xFFFFFF,     $__DM_g_iBtnBorderFocLight   = 0xBCBCBC
Global $__DM_g_iBtnBorderDis,       $__DM_g_iBtnBorderDisDark   = 0x404040,     $__DM_g_iBtnBorderDisLight   = 0xBCBCBC
