Needs black-box testing against Delphi, especially when either no active form exists yet, or
when the active form's Active property is False (e.g. minimized, hidden of a non-LCL form is shwoing modally).
Also needs to be debated wether the return value should be TLCLHandle.
The implementation differs from the one in (now deprecated) LCLTaskDialog:
- the type of query is controlled by flags only (which are mutually exclusive)
- for single line edit, you can set passwordchar
- intial value of single line query has no influence on combobox
- initial value of combobox is controlled by integer value, not by text
- first attempt to get Win32 WS code working (currently littered with writeln() statements, so crashes if no console!)
- fix ModalResult in OnButtonClicked for emulated dialog.
- Change signature of TWSTaskDialog.Execute and related functions/methods so we can set ParentWnd and retrieve RadioRes.
The TLCLTaskDialog now should act the same as the old emulated version (unit LCLTaskDialog).
- Use meaningfull names for private vars of TLCLTaskDialog
- Factor out SetupPanel
- Consistent capitalization of "Result" ,"True" and "False"
- Remove property VerifyChecked, set appropriate flag instead
- More debugln statements
- Add some comments
The emulated dialog is now more or less functional (we don't return RadioResult yet).
- Fix not displaying common buttons in TLCLTaskDialog.SetupControls
- Assign TLCLDialog.FDlg in the CreateNew() constructor.
- Free LDefaultFont
- Start comparing the new form vs the old form
Still not functional.
- expose Dialogs.TTaskDialog.ParentWindow as reado only property (needed in TLCLTaskDialog.Execute)
- furhter implement adding controls at runtime to TLCLTaskDialog
- it compiles, but still not functional.
- Deprecated unit LCLTaskDialog.
- Unit TaskDlgEmulation: work in progress.
- Start implementing TLCLTaskDialog class. Not functional yet (but at least it should compile).
- Code copied and adapted from the now deprecated LCLTaskDialog unit.
- Temporarily exposed a private variable of Dialogs.TTaskDialog
This reverts commit 9f577dc548.
Reasons:
1. The logic of VCL_OnClick_Emulation flag (or its name) is wrong: when it is true, OnChange event gets called LCL-style (note that VCL does not have OnChange event).
2. Having such flag is unsafe: e.g. some used unit can disable it and checkboxes in the whole program will _silently_ change their behavior.
3. The code claimed as a reason for introducing this change does not work in Delphi too.
Such Delphi compatibility issues should be handled another way.
Closes: #37712.
When mouse moves but remains over the same widget, we should not
recreate the hint window. Just break execution and 'exit `ActivateHint`
function early.
Closes#40331.
GTK3 WS needs to get that handle in order to retrieve the parent window
which need to be set as transient of the newly created popup window.
This is a required by GTK3 documentation as one can see in
https://docs.gtk.org/gtk3/method.Window.set_transient_for.html
This patch needs to touch common LCL code, but `HintData` files does
not seem to be really used.
1. MarkAsChanged method (protected) is added, which sets FChanged to
true.
2. Virtual DoAfterUpdateStarted and DoBeforeUpdateEnded methods
(protected) are added. They are called in first BeginUpdate and last
EndUpdate respectively.
