LarsJ Posted March 5, 2012 Share Posted March 5, 2012 (edited) I was looking for some examples of custom drawn TreeViews. I didn't find any so here is two. I have made the examples for ListViews too. The first example shows some named colors from the MS HTML documentation. The colors are sorted in different ways in five text files in the zipfile. The forecolor, backcolor, color name and RGB value is shown in the GUI's. Remark that the forecolor in the first column in the ListView is bold. Click on the colors in the TreeView to see some of the effects of custom drawing. The second example enumerates the fonts for the character sets in FontConstants.au3 and shows the fonts in the GUI's. Click on the fonts in the TreeView to see the name of the fonts. The zipfile contains 5 text files with color definitions and 4 au3-files with GUI's.

jcpetu Posted September 10, 2012 Share Posted September 10, 2012 Hi LarsJ, nice example and code. is it possible to paint the selected row in a color other than blue? Link to comment Share on other sites More sharing options...
LarsJ Posted September 13, 2012 Author Share Posted September 13, 2012 (edited) jcpetu, Yes it is. The key point is to set the selected state of the selected item to false. If you only use single selection you can use the focused state to keep track of the selected item. If you use multiple selections you have to keep track of the selected items yourself. In the example in the zip (you need the text files from the original zip) the focused state is used to keep track of the selected item which is painted with a cyan backcolor. Regards Lars lvCustDrawColors2.zip 2016-03-22: For a better way to change background color of selected rows take a look at Colors and fonts in custom drawn ListViews - UDF version. Changing state values to be able to set the background color, as is done here, can easily become a mess.

DarkAaly Posted September 1, 2013 Share Posted September 1, 2013 (edited) Thanks for the reply. This is a small script that they asked me to do, I would like to change the font or color to the folders that contain characters in the name, such as "[APERTA]", "[CHIUSA]" and "[sOSPESA]," but in 'example above was applied to a list. Thank you. EDIT: The example that I needed stop working when I try to run "vCustDrawColors.au3" and "tvCustDrawFonts.au3" works but the font do not change.

weirddave Posted March 10, 2015 Share Posted March 10, 2015 This does indeed work. I'm now trying to understand what it's actually doing. The log window I'm trying to create will need to keep the colour/color, so I figured just comment out all but the last row third column case. This didn't work, I assume because all of the items are being redrawn. So, changed it so that only the last row is redrawn. At first I thought this was working, but as the window filled up and items scrolled off the bottom, I realised that they were losing their colour information. Does this mean I need to create an ever expanding list containing the colour for each item?

At first I thought this was working, but as the window filled up and items scrolled off the bottom, I realised that they were losing their colour information. Does this mean I need to create an ever expanding list containing the colour for each item? Here's my lightly modified code: Here's some code to get you started: expandcollapse popup#include <GUIConstants.au3> #include <WindowsConstants.au3> #include <FontConstants.au3> #include <GuiListView.au3> #include <WinAPI.au3> Global $idLast1 = -1, $idLast2 = -1 ; Last and second last row $MyGUI = GUICreate("listview items", 320, 200, 0,-1, -1) _WinAPI_SetClassLongEx($MyGUI, -26, BitAND(_WinAPI_GetClassLongEx($MyGUI, -26), BitNOT(1), BitNOT(2))) $idListview = GUICtrlCreateListView("A|B|C", 10, 10, 250, 155, 0x200) _GUICtrlListView_SetExtendedListViewStyle($idListview, $LVS_EX_DOUBLEBUFFER) $hLV = ControlGetHandle($MyGUI, "", $idListview) $idButton = GUICtrlCreateButton("Add", 125, 175, 70, 20) $hListview = GUICtrlGetHandle( $idListview ) $hDC = _WinAPI_GetDC($hLV) $hFont = _SendMessage($hLV, $WM_GETFONT) $hObject = _WinAPI_SelectObject($hDC, $hFont) $lvLOGFONT = DllStructCreate($tagLOGFONT) $aRet = DllCall('gdi32.dll', 'int', 'GetObjectW', 'ptr', $hFont, 'int', DllStructGetSize($lvLOGFONT), 'ptr', DllStructGetPtr($lvLOGFONT)) _WinAPI_SelectObject($hDC, $hObject) _WinAPI_ReleaseDC($hLV, $hDC) $hLVfont = _WinAPI_CreateFontIndirect($lvLOGFONT) $iWeight = BitOR( DllStructGetData($lvLOGFONT, "Weight"), $FW_BOLD) DllStructSetData( $lvLOGFONT, "Weight", $iWeight) $hLVfontBold = _WinAPI_CreateFontIndirect($lvLOGFONT) GUIRegisterMsg( $WM_NOTIFY, "WM_NOTIFY" ) GUISetState(@SW_SHOW) while 1 $msg = GUIGetMsg() Switch $msg Case $GUI_EVENT_CLOSE ExitLoop Case $idButton $idLast1 = GUICtrlCreateListViewItem("a|b|c", $idListview) $itemcount = _GUICtrlListView_GetItemCount( $hListview ) - 1 _GUICtrlListView_RedrawItems( $hListview, $itemcount, $itemcount) EndSwitch wend Func WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam) #forceref $hWnd, $iMsg, $wParam Local $tNMHDR, $hWndFrom, $iCode $tNMHDR = DllStructCreate($tagNMHDR, $lParam) $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom")) $iCode = DllStructGetData($tNMHDR, "Code") Switch $hWndFrom Case $hLV Switch $iCode Case $NM_CUSTOMDRAW Local $tNMLVCUSTOMDRAW = DllStructCreate($tagNMLVCUSTOMDRAW, $lParam) Local $dwDrawStage = DllStructGetData($tNMLVCUSTOMDRAW, "dwDrawStage") Switch $dwDrawStage Case $CDDS_PREPAINT Return $CDRF_NOTIFYITEMDRAW Case $CDDS_ITEMPREPAINT Return $CDRF_NOTIFYSUBITEMDRAW Case BitOR( $CDDS_ITEMPREPAINT, $CDDS_SUBITEM ) Local $iSubItem = DllStructGetData($tNMLVCUSTOMDRAW, "iSubItem") Local $dwItemSpec = DllStructGetData($tNMLVCUSTOMDRAW, "dwItemSpec") Local $hDC = DllStructGetData($tNMLVCUSTOMDRAW, "HDC") Switch $iSubItem Case 2 _WinAPI_SelectObject($hDC, $hLVfont) DllStructSetData( $tNMLVCUSTOMDRAW, "ClrText", ColorConvert(0x000000)) DllStructSetData( $tNMLVCUSTOMDRAW, "ClrTextBk", ColorConvert(0xFF0000)) Case Else _WinAPI_SelectObject($hDC, $hLVfont) DllStructSetData( $tNMLVCUSTOMDRAW, "ClrText", ColorConvert(0x000000)) DllStructSetData( $tNMLVCUSTOMDRAW, "ClrTextBk", ColorConvert(0xFFFFFF)) EndSwitch Return $CDRF_NEWFONT EndSwitch EndSwitch EndSwitch Return $GUI_RUNDEFMSG EndFunc Func ColorConvert($iColor) Return BitOR(BitAND($iColor, 0x00FF00), BitShift(BitAND($iColor, 0x0000FF), -16), BitShift(BitAND($iColor, 0xFF0000), 16)) EndFunc As you can see we custom draw the red bg in column 2 but we also custom draw all other colums as normal (white bg/black text) I've set a couple of styles to the GUI and the ListView to remove any flicker when scrolling etc Edited March 10, 2015 by mpower Link to comment Share on other sites More sharing options...
weirddave Posted March 10, 2015 Share Posted March 10, 2015 I need the colour in column 2 to be dependent on some other variable, not always red, but once it's set to red, green or white, I don't want to change it, it's so I can quickly locate problems which are being logged. A bit of googling suggests there may be a limit on the number of items I can add to the listview, am I going down completely the wrong path for a log window?
