I just upgraded the Delphi IDE to 12.2 (with patch 1.0), also firepowerX3 latest version has been installed.

I have a simple project with a TEdit and a TwwEdit, the text "TEST" is automatically filled in by clicking on a button.

When I go to the TwwEdit and make sure the cursor is at the end of the textfield the delete button on the android touchscreen has no effect, also the OnKeyDown or OnKeyUp event is apparently never fired with the delete button. When moving the cursor to another place the delete button responds again and the OnKeyDown and OnKeyUp events are also fired again.

It also seems that the text is still selected in full while the cursor is blinking at the end of the textfield.

The TEdit responds normal, only the TwwEdit has this issue.

Any Idea where the problem might be?

 

I am using Delphi 12.2 with patch 1.0

AndroidSDK-2525-23.0.53982.0329

AndroidNDK-21-23.0.53982.0329

Eclipse Adoptium\jdk-21.0.5.11-hotspot

The android device has Android 10 installed

  Please provide a simple project showing the problem.  Also what do you mean by vk_delete. I seem to only have backspace on my android keyboard. vk_delete on desktop normally removes the forward character not the previous character.

  I put a sample project op weTransfer:

  Indeed in Android there is only a backspace visible but in code it is vk_delete.

  Also in desktop (windows) when the TwwEdit is selected with the mouse pointer the complete text is selected. This is probably also the case in Android but not visible since the cursor is blinking at the end of the text and possibly why the backspace is not responding.

  In your sample project, your TEdit has autoselect=false and your TwwEdit has autoselect=true so your properties are not the same. If you want to disable autoselect, then set your TwwEdit to false.
