| Summary | 0006105: TJvCheckBox.CalcAutoSize | ||||
| Description | In some Windows themes checkboxes (and radiobutton) has its own font. Even if you assign the font you want to see nothing changes and Windows paint control with its "personal" font. In this case procedure TJvCheckBox.CalcAutoSize calculates wrong size because it use font assigned by user but must use "personal" font of control. There is a screenshot in the attached file which show current result of TJvCheckBox.CalcAutoSize and result of function which I want to offer. My source code in the Additional Information. | ||||
