Hi.

I am working on an editor and one of it's features is an internal Entity-Editor.
I use (like often in past projects) BlueGUI for a good interface, but there is another strange bug (had many so far, but solved most.. as always mostly they are not "bugs" but just wrong code, probably this time too

), and have really no idea why it occurs and how I can solve it.

The problem is, that there is an image-panel (normal panel with assigned image) and I resize it to the image's size each time the image changes. But as soon as I use "setpanelimage" with the new image the size is changed to the creation-time-size (128*128 pixels), no matter how big the used image is (in the moment before it has the right size, but changes as soon as I use this command).

Here's the function which is responsibly for applying an image and resizing the window and gadget:

+ Code Snippet


function GUI_EE_SetImage(ID)
   GUI_EE_Image = ID
   rem Image-Size
   GUI_EE_WindowSX = 50 + image width(GUI_EE_Image)
   GUI_EE_WindowSY = 250 + image height(GUI_EE_Image)
   rem Size image
   setgadget GUI_EE_ImagePanel, gadgetX(GUI_EE_ImagePanel), gadgetY(GUI_EE_ImagePanel), GUI_EE_WindowSX-50, GUI_EE_WindowSY-250
   rem The panel has the right size here  ^
   rem And is resized to 128*128 px there v
   setpanelimage GUI_EE_ImagePanel, GUI_EE_Image
   rem Size window
   if GUI_EE_WindowSX < GUI_EE_WindowMinSX then GUI_EE_WindowSX = GUI_EE_WindowMinSX
   if GUI_EE_WindowSY < GUI_EE_WindowMinSY then GUI_EE_WindowSY = GUI_EE_WindowMinSY
   setgadget GUI_EE_Window, gadgetX(GUI_EE_Window), gadgetY(GUI_EE_Window), GUI_EE_WindowSX, GUI_EE_WindowSY
endfunction

I hope anyone understands my problem.

Thanks in advance for any help.

I have experienced the same problems, so don't worry.

Here's a little example to illustrate the problem:

+ Code Snippet

`Create images
cls rgb(255, 0, 0)
get image 1, 0, 0, 50, 50, 1
cls rgb(0, 255, 0)
get image 2, 0, 0, 50, 50, 1
cls rgb(0, 0, 255)
get image 3, 0, 0, 50, 50, 1
cls 0

cp = createPanel(5, 5, 200, 200, 0)
setPanelImage cp, 1

do

    if inkey$() = "1" then setPanelImage cp, 1
    if inkey$() = "2" then setPanelImage cp, 2
    if inkey$() = "3" then setPanelImage cp, 3
    if lower$(inkey$()) = "s" then ResizeGadget cp, 200, 200

loop

make memblock 1, 0

You see, everytime you change the image, the panel resizes itself to the image size. But if you press s when loaded, you can stretch the image to your desired size.

You'll just have to resize it again and again after each time you change the panel image.

It's the programmer's life:
Have a problem, solve the problem, and have a new problem to solve.
