Is there a way to change the cursor when you are over the grabber? I think this would help clarify when to try and resize or more a gadget.

Hi Bericko

This new one works great here.

To avoid that everything is repainted with any movement of the gadget you can only repaint the lines and the points... i know its demand to store the position of every line and point and then invalidate the rect of every one and repaint only this part of the screen, but the result is more 'stable'.

Im coding myself a little gui builder on PB if you want (or anybody) to check my code or maybe give me some feedback, send me an email to [url]mailto:ricardoarias@yahoo.com">ricardoarias@yahoo.com (sendinf mails from the forums dosent works anymore!!).

I have found some solutions to make the gui-builder works smooth on every gadget but still have some bugs

A small example that drags/resize almost every gadget (still have bugs and dont generate any code, tis just a test)

Feedback (ideas and helping hands) are welcome!!

Best Regards

Ricardo

In fact Windows offers itself a way to resize gadgets. Its comfortable since windows manage all the resize stuff transparently, but...

Its not 'elegant' but work well with most gadgets, but some -combo per example- cant get rid off some line that stay there, take a look:

Code: Select all


If OpenWindow(0, 10, 10, 450, 450, #PB_Window_SystemMenu, "Test")
  CreateGadgetList(WindowID())
  ButtonGadget(0, 10, 10, 150, 25, "Resize Mode= Off",#PB_Button_Default|#PB_Button_Toggle)
  ButtonGadget(1, 200, 100, 120, 25, "Drag Me")
  ComboBoxGadget(2,160,60,80,75,"Combobox5")
  MessageRequester("Info","Click the gadget that you want to resize and the push the design button",0)

  Repeat
    EventID = WaitWindowEvent()
    
    Select EventID

              HideGadget(Selected,1);Neccesary to dissapear the frame of the button (why?)
              HideGadget(Selected,0)
