FMX Controls-Demo: What does not work

[Harry Stahl]

• Multiselect of ListboxItems: No effect (TabItem Standard)
• After performing "Switch to 3D and Back" the form does not react (freeze)
• Drag and drop does not work (TabItem Ext Controls)
• For the scrollbar only the selection thumb is visible (TabItem Standard)

[Zoltan Karpati]

It does not show the MainMenu.

[Eugene Kryukov]

It shows main menu on app-menu position (like on macOS)

[Zoltan Karpati]

You have right, I did search it on the Mainform.

If I run the ControlsDemo (or other FMX programs) from the terminal, the terminal shows the following message: gtk_widget_destroy: assertion 'GTK_IS_WIDGET (widget)' failed

[Canqi Luo]

Yes, this like my report bug.

I run it on Lubuntu 14.04

deepin 15.4 rc2

http://cdimage.deepin.com/releases/15.4.rc/deepin-15.4-rc2-amd64.iso

run Controls-Demo

(ControlsDemo:2817): WARNING : Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-WM6NCEcWgO: Refused

(ControlsDemo:2817): Gtk-CRITICAL **: gtk_widget_destroy: assertion 'GTK_IS_WIDGET (widget)' failed

And some components did not work. such as if you click the first tab control, "Standard", the program did not change to Standard tab, it will display the popup menu on the bottom of the form.

I used the v0.95 and I can't compile all of my FMX programs that works with v0.94

[DCC Fatal Error] ControlsDemo.dpr(18): F2063 Could not compile used unit 'FMX.SpellChecker'

[Eugene Kryukov]

Can you post whole compiler log ?

[Zoltan Karpati]

I don't know what was the problem, but this morning I reinstalled the v0.95 and it is works fine.

[Zoltan Karpati]

What's about the following problem (#39: Viewport3D.Multisample problem)?

If the Viewport3D.Multisample.None it works fine. If the Viewport3D.Multisample.TwoSamples or FourSamples it draws nothing.

[Eugene Kryukov]

It works fine on our system. Please do not ask about other issue in this thread. If your issue still opened this mean, that we are working on it. Is is this thread can be closed ?

[Zoltan Karpati]

Yes, you can close this thread.
