3. 1 VI1 221 CVM 1 VI1 224 Another option would be to draw the level control at the bottom of the SCADA screen and use various paint pot controls to paint the desired zone Thus we could draw on the screen background something like the following The inner part although it seems all the same color white it is not and is divided into grids with different whites indistinguishable one from the other and by the human eye for example it is impossible to distinguish between white RGB 255 255 255 and white RGB 254 255 255 Then we place the paint pot on each table with the desired condition and tolerance 0 to prevent painting adjacent tables which are very similar in color With this the result is a progress bar or control level which can be configured as desired 3 2 20 How can change the properties of control in accordance with a condition The properties of control cannot be changed in accordance with a condition However we can simulate the change of these properties using a conditional control Thus for example if we wish to change the color of a text in accordance with a condition we add a conditional control with two text type controls which are exactly the same but of a different color and specify which conditions need to be fulfilled for each one to be shown Likewise we can also change the orientation font size etc We can also make a control be an image or a text in accord
