textCrtrl custom renderer

Sebastian_Lopez · October 26, 2014, 3:55pm

I would like to create a text control that works in this way:

If the text control is empty then the control shows a default text

In the other hand the control shows the user’s input.

But i don’t know how to set a custom renderer of a textCtrl

You want to read up on "wx.EVT_TEXT".

Hi

I append my approach by using wx.EVT_KEY_DOWN and wx.EVT_KEY_UP but I also like to know if it’s possible to change the text color in the control to being sometimes black color and sometimes grey color.

defaultTxtTest.py (1.54 KB)

You could use a wx.SearchCtrl with the SearchButton, CancelButton ect
set to not be shown and use the method SetDescriptiveText for setting your default text.

The search control is a wx.TextCtrl with added functionality.

I would use EVT_SET_FOCUS and EVT_KILL_FOCUS.

By default on startup you’d set the color style of the TextCtrl to light-grey and set ChangeValue to the default text. Then in the EVT_SET_FOCUS handler, if the default text is shown ChangeValue(‘’) and set the text style to the normal black color. In the EVT_KILL_FOCUS handler, if the GetValue() is ‘’ (blank), set the light-grey text style and ChangeValue(defaultText).

I don’t think that’s the right model. He’s looking for the same
functionality as the “placeholder” attribute in a modern HTML
tag. ANY time the box goes empty, it displays the
placeholder property in a grayed color. As soon as one character is
entered, the placeholder goes away and it displays the entered text
in black.
I think you have to use key up and key down. Either that, or
subclass the edit control and draw the placeholder during the paint
event.
