Creating Buttons with GDI+

3 posts in this topic

#1 ·  Posted (edited)

Hi, i am trying create buttons with GDI, i need help about how can i interact to change color of the button when mouse hover. I think who have a better way than monitor mousecoords and if mouse about "some" coord x,y then change blabla

#include <GUIConstantsEx.au3>
#include <GDIPlus.au3>

Example()

Func Example()
    Local $hGUI, $hGraphic

    ; Create GUI
    $hGUI = GUICreate("GDI+", 400, 300)
    GUISetState(@SW_SHOW)

    ; Fill a rectangle
    _GDIPlus_Startup()
    $hGraphic = _GDIPlus_GraphicsCreateFromHWND($hGUI)
    $hBrush = _GDIPlus_BrushCreateSolid(0xFF43A6DF)
    $hBrushFont = _GDIPlus_BrushCreateSolid(0xFFFFFFFF)
    $hFormat = _GDIPlus_StringFormatCreate()
    _GDIPlus_GraphicsFillRect($hGraphic, 10, 10, 100, 100, $hBrush)
    $hFamily = _GDIPlus_FontFamilyCreate("Segoe UI Light")
    $hFont = _GDIPlus_FontCreate($hFamily, 20, 2)
    $tLayout = _GDIPlus_RectFCreate(10, 10, 100, 100)
    _GDIPlus_GraphicsDrawStringEx($hGraphic, "Hello world", $hFont, $tLayout, $hFormat, $hBrushFont)
    ; Loop until the user exits.
    Do
    #cs
    $aCI = GUIGetCursorInfo($hGUI)
    If $aCI[4] = $hFont Then
        MsgBox(0,"","")
    EndIf
    #ce
    Until GUIGetMsg() = $GUI_EVENT_CLOSE

    ; Clean up resources
    _GDIPlus_GraphicsDispose($hGraphic)
    _GDIPlus_Shutdown()
EndFunc   ;==>Example

Use WM_PAINT to draw on the GUI, orelse with your code try to minimize + restore you will find that all the graphics disappear.

For your question check the function CheckPointer in the example.

Example

#include <GUIConstantsEx.au3>
#include <GDIPlus.au3>
#include <WindowsConstants.au3>
#include <WinAPIGdi.au3>

Global $hGraphic, $hBrush, $hBrushFont, $hFont, $hFormat, $hFamily, $hGUI, $tRect_Coords[4] ;would be used in two functions therefore declared as global.
Global $iTheme = 0

Example()

Func Example()

    ; Create GUI
    $hGUI = GUICreate("GDI+", 400, 300)

    ; Fill a rectangle
    _GDIPlus_Startup()
    $hGraphic = _GDIPlus_GraphicsCreateFromHWND($hGUI)
    $hBrush = _GDIPlus_BrushCreateSolid(0xAA43A6DF)
    $hBrushFont = _GDIPlus_BrushCreateSolid(0xFFFFFFFF)
    $hFormat = _GDIPlus_StringFormatCreate()
    $hFamily = _GDIPlus_FontFamilyCreate("Segoe UI Light")
    $hFont = _GDIPlus_FontCreate($hFamily, 20, 2)
    $tRect_Coords[0] = 10
    $tRect_Coords[1] = 10
    $tRect_Coords[2] = 100
    $tRect_Coords[3] = 100

    ;Register for painting
    GUIRegisterMsg($WM_PAINT, "WM_PAINT") ;$WM_PAINT

    GUISetState()

    ; Loop until the user exits.
    Do
        Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE
                ExitLoop

            Case $GUI_EVENT_PRIMARYDOWN
                If CheckPointer($tRect_Coords) Then SetTheme(1)

            Case $GUI_EVENT_PRIMARYUP
                SetTheme(0)

            Case $GUI_EVENT_MOUSEMOVE

                If GetTheme() = 1 Then ContinueLoop

                If CheckPointer($tRect_Coords) Then
                    SetTheme(2)
                Else
                    SetTheme(0)
                EndIf

        EndSwitch

Func WM_PAINT($hGUI, $iMsg, $wParam, $lParam)

    _WinAPI_RedrawWindow($hGUI, 0, 0, $RDW_UPDATENOW)

    ;Your Code must lie below
    ;Paint the string

    _GDIPlus_GraphicsClear($hGraphic, 0xFFF0F0F0)

    ConsoleWrite("CurTheme: " & $iTheme & @CRLF)
    If $f_Redraw Then _WinAPI_RedrawWindow($hGUI, 0, 0, BitOR($RDW_INTERNALPAINT, $RDW_ERASE))

endfunc   ;==>SetTheme 

Thumbs up if it helped.
