Hi All
WebDev 23 - Dynamic site.
Any easy, nice way to allow a user to pick a colour either from a pallete or from a preset list of colours (e.g. the WB colour constants) ?
Thanks |

Hi JP
I did that a few years back with a cell and a series of boutons, each of the color to select... Took me a good 10 minutes.
Easy enough?
Best regards |

Fabrice,
OK, sure - I was just checking there was no easy colour picker like in WinDev
However, using a cell and some coloured buttons is fine but how do I return the colour selected back to the calling routine so that it can process the colour selected? |

Hi,
in the click of button code you set the chosen color in your result variable... But that is clearly too simple to be the answer to the REAL question that I didn't understand...
Best regards |

Hello JP,
I do this with 3 sliders set from 1 to 255. (red,green and blue) Then I have 3 edit controls to show the numbers EDT_Red , EDT_Green and EDT_blue. Last I have a cell that I change the background color if the user changes the slider of types in a number in the edit controls
On the slider code for red slider EDT_Red = MySelf lp_SetColor() Code for any of the color edit controls lp_SetColor()
PROCEDURE lp_SetColor() //Calulates the color CELL_Color..BrushColor = RGB(EDT_Red,EDT_Green,EDT_Blue) //This is a edit field hidden for me only that shows the color hex EDT_Color_Hex = 65536 * EDT_Blue + 256 * EDT_Green + EDT_Red DW |

lol - I understand how to retrieve brushcolor and all that. My problem is a design / operational desire rather than a technical issue. I want to let the user choose a colour and, when he does so, it updates the button brushcolor which was used for selecting the colour picker and then auto update a chart with the selected colour. I have worked out a working solution using the cell option you suggested. Thanks! |

Thanks, a nice solution. I wonder also if one could display a colour chart (like in WinDev colour selector) and then reocrd the X,Y coordinates of a mouse click and figure out the colour of the pixel clicked on... But anyway, I got a working solution but might give your suggestion a go too.
Thanks! |

Hi JP,
Not out of the box, but it's a few minutes work to create a little multi-column looper, that only contains a 16 x 16 sized button. The button has a style without border/background. In the looper you use an Attribute for the returned color and to set the background color of the button.
The click of a button returns the color. I use the following code to offer some basic colors: LooperAddLine(LOOP_Color,RGB(148,148,148)) FOR i=65 TO 215 STEP 75 LooperAddLine(LOOP_Color,RGB(255, i, 0)) END LooperAddLine(LOOP_Color,RGB(196, 196, 196)) FOR i=75 TO 195 STEP 60 LooperAddLine(LOOP_Color,RGB(i, 255, 0)) END LooperAddLine(LOOP_Color,RGB(160, 120, 120)) FOR i=105 TO 255 STEP 75 LooperAddLine(LOOP_Color,RGB(75, i, 255)) END LooperAddLine(LOOP_Color,iLightYellow) FOR i=75 TO 255 STEP 60 LooperAddLine(LOOP_Color,RGB(255, i, 255)) END Kind regards, Piet |
