Description
If the alpha blend ratio is determined for the column caption,
1. | it examines whether a bBrowserColumn:CaptionView object is defined for the column and whether the alpha blend ratio (see also bViewStyle:AlphaBlendRatio) in this object is set unequal to BABR_AUTO. Ü If it is, this value is returned. |
2. | it examines whether a bBrowser:CaptionView object is defined for the browser and whether the alpha blend ratio (see also bViewStyle:AlphaBlendRatio) in this object is set unequal to BABR_AUTO. Ü If it is, this value is returned. |
3. | it is examined whether in the access bBrowser:AlphaBlendRatio a value is set unequal to BABR_AUTO. Ü If it is, this value is returned. |
4. | Ü the aplha blend ratio BABR_NORMAL is returned. |
If the alpha blend ratio is determined for the column values,
1. | it examines whether a bBrowserColumn:DataView object is defined for the column and whether the alpha blend ratio (see also bViewStyle:AlphaBlendRatio) in this object is set unequal to BABR_AUTO. Ü If it is, this value is returned. |

3. | it is examined whether in the access bBrowser:AlphaBlendRatio a value is set unequal to BABR_AUTO. Ü If it is, this value is returned. |
4. | Ü the aplha blend ratio BABR_NORMAL is returned. |
If the alpha blend ratio is determined for the column footer,
1. | it examines whether a bBrowserColumn:FooterView object is defined for the column and whether the alpha blend ratio (see also bViewStyle:AlphaBlendRatio) in this object is set unequal to BABR_AUTO. Ü If it is, this value is returned. |
2. | it examines whether a bBrowser:FooterView object is defined for the browser and whether the alpha blend ratio (see also bViewStyle:AlphaBlendRatio) in this object is set unequal to BABR_AUTO. Ü If it is, this value is returned. |
