events lost in tranparent window

Post by williamvanhoecke »

Hello i am trying to create a transparent window that contains buttons. Transparency is needed because the buttons control the image behind the window. (see image: https://photos.app.goo.gl/bMBo2dhqeButYnzYA)
Every button should fire an event and when clicking in the middle of the window underneath gets focus.
However some buttons never fire their event!
Anyone knows what is happening here ?

Code: Select all

Enumeration
  #SYMBOL_SIZE_UP_BUTTON
  #SYMBOL_SIZE_DOWN_BUTTON
  #SYMBOL_HFLIP_BUTTON
  #SYMBOL_VFLIP_BUTTON
  #SYMBOL_COPY_BUTTON
  #SYMBOL_SETTINGS_BUTTON
  #SYMBOL_EXIT_BUTTON
  #SYMBOL_DELETE_BUTTON
  #SYMBOL_ROTATE_LEFT_BUTTON
  #SYMBOL_ROTATE_RIGHT_BUTTON
  
  #SYMBOL_SIZE_TEXT
  #SYMBOL_ROTATE_TEXT
EndEnumeration  
butw = 25
maskcolor = RGB(0,0,0)
